Abstract

The Securities and Exchange Commission ("Commission" or "SEC") is proposing to amend existing requirements under the Securities Exchange Act of 1934 ("Exchange Act") to update the disclosure required for order executions in national market system ("NMS") stocks. First, the Commission is proposing to expand the scope of reporting entities subject to the rule that requires market centers to make available to the public monthly execution quality reports to encompass broker-dealers with a larger number of customers. Next, the Commission is proposing to modify the definition of "covered order" to include certain orders submitted outside of regular trading hours and certain orders submitted with stop prices. In addition, the Commission is proposing modifications to the information required to be reported under the rule, including changing how orders are categorized by order size as well as how they are categorized by order type. As part of the changes to these categories, the Commission is proposing to capture execution quality information for fractional share orders, odd- lot orders, and larger-sized orders. Additionally, the Commission is proposing to modify reporting requirements for non-marketable limit orders ("NMLOs") in order to capture more relevant execution quality information for these orders by requiring statistics to be reported from the time such orders become executable. The Commission is also proposing to eliminate time-to-execution categories in favor of average time to execution, median time to execution, and 99th percentile time to execution, each as measured in increments of a millisecond or finer and calculated on a share-weighted basis. In order to better reflect the speed of the marketplace, the Commission is proposing that the time of order receipt and time of order execution be measured in increments of a millisecond or finer, and that realized spread be calculated at both 15 seconds and one minute. Finally, the Commission is proposing to enhance the accessibility of the required reports by requiring all reporting entities to make a summary report available.

Disclosure of Order Execution Information

AGENCY: Securities and Exchange Commission.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Securities and Exchange Commission (``Commission'' or 
``SEC'') is proposing to amend existing requirements under the 
Securities Exchange Act of 1934 (``Exchange Act'') to update the 
disclosure required for order executions in national market system 
(``NMS'') stocks. First, the Commission is proposing to expand the 
scope of reporting entities subject to the rule that requires market 
centers to make available to the public monthly execution quality 
reports to encompass broker-dealers with a larger number of customers. 
Next, the Commission is proposing to modify the definition of ``covered 
order'' to include certain orders submitted outside of regular trading 
hours and certain orders submitted with stop prices. In addition, the 
Commission is proposing modifications to the information required to be 
reported under the rule, including changing how orders are categorized 
by order size as well as how they are categorized by order type. As 
part of the changes to these categories, the Commission is proposing to 
capture execution quality information for fractional share orders, odd-
lot orders, and larger-sized orders. Additionally, the Commission is 
proposing to modify reporting requirements for non-marketable limit 
orders (``NMLOs'') in order to capture more relevant execution quality 
information for these orders by requiring statistics to be reported 
from the time such orders become executable. The Commission is also 
proposing to eliminate time-to-execution categories in favor of average 
time to execution, median time to execution, and 99th percentile time 
to execution, each as measured in increments of a millisecond or finer 
and calculated on a share-weighted basis. In order to better reflect 
the speed of the marketplace, the Commission is proposing that the time 
of order receipt and time of order execution be measured in increments 
of a millisecond or finer, and that realized spread be calculated at 
both 15 seconds and one minute. Finally, the Commission is proposing to 
enhance the accessibility of the required reports by requiring all 
reporting entities to make a summary report available.

I. Introduction

    The Commission is proposing to update the requirements to disclose 
order execution information under Rule 605. Currently, market centers 
that execute investor orders are required to make monthly disclosures 
of basic information concerning their quality of executions. The 
required disclosures have provided significant insight into execution 
quality at different market centers; however, both the scope and the 
content of Rule 605 reports have not kept pace with technological and 
market developments. The proposal would require broker-dealers with a 
larger number of customers (``larger broker-dealers'') \1\ to prepare 
execution quality reports, would capture execution quality information 
for more order types and sizes, and would require time-based metrics to 
be recorded at a more granular level that reflects current market 
speed. By providing more relevant and accessible metrics, the proposal 
would better promote competition among market centers and broker-
dealers on the basis of execution quality and ultimately improve the 
efficiency of securities transactions, consistent with the national 
market system objectives.\2\
---------------------------------------------------------------------------

    \1\ Throughout the release, the term ``larger broker-dealer'' 
refers to a broker-dealer that meets or exceeds the ``customer 
account threshold,'' as defined in proposed Rule 605(a)(7). See also 
infra section III.A (discussing proposed Rule 605(a)(7)).
    \2\ 15 U.S.C. 78k-1.
---------------------------------------------------------------------------

    The national market system objectives of section 11A of the 
Exchange Act include the economically efficient executions of 
securities transactions; fair competition among brokers and dealers, 
among exchange markets, and between exchange markets and markets other 
than exchange markets; the availability of information on securities 
quotations and transactions; and the practicability of brokers 
executing investor orders in the best market.\3\ These objectives guide 
the Commission as it seeks to ensure market structure rules keep pace 
with continually changing economic conditions and technological 
advancements. However, these objectives, in particular the goal of 
promoting opportunities for the most willing seller to meet the most 
willing buyer (i.e., order interaction) and the goal of promoting 
competition among markets, can be difficult to reconcile.\4\ The Rule, 
along with 17 CFR 242.606 (``Rule 606'') of Regulation NMS, was adopted 
in 2000 and together these rules required the public disclosure of 
execution quality and order routing practices.\5\ In adopting these 
rules, the Commission recognized the importance of vigorous competition 
among buyers and sellers in an individual security.\6\ However, the 
Commission also recognized the importance of competition among market 
centers, which entails some fragmentation of order flow.\7\ Such 
competition has benefits to investors including the development of 
innovative trading services, lower fees, and faster executions.\8\ The 
Commission characterized the rules as a ``minimum step necessary to 
address fragmentation'' \9\ and stated that by making visible the 
execution quality of the securities markets, the rules are intended to 
spur more vigorous competition among market participants to provide the 
best possible prices for investor orders.\10\
---------------------------------------------------------------------------

    \3\ See 15 U.S.C. 78k-1(a)(1)(C).
    \4\ See Securities Exchange Act Release No. 61358 (Jan. 14, 
2010), 75 FR 3594, 3597 (Jan. 21, 2010) (``Concept Release on Equity 
Market Structure'').
    \5\ See Securities Exchange Act Release No. 43590 (Nov. 17, 
2000), 65 FR 75414, 75416 (Dec. 1, 2000) (Disclosure of Order 
Execution and Routing Practices) (``Adopting Release'').

---------------------------------------------------------------------------

    Although the Rule has provided visibility into execution quality at 
different market centers, the content of the disclosures required by 
the Rule has not been substantively updated since the Rule was adopted 
in 2000.\11\ Changed equity market conditions and technological 
advancements have eroded the utility of the Rule. The speed and nature 
of trading have changed dramatically as a result of technological 
improvements and the markets' response to the changing regulatory 
landscape.\12\ Trading has moved from being concentrated on a given 
security's listing exchange \13\ to being spread across a highly 
fragmented market where national securities exchanges, alternative 
trading systems (``ATSs''), single-dealer platforms (``SDPs''), off-
exchange market makers, and others compete for order flow. Orders may 
be matched, routed, or cancelled in microseconds and market information 
is transmitted nearly instantaneously. At the same time, individual 
investor \14\ participation in the equity markets has increased.\15\ 
Further, the average share prices of certain stocks have continued to 
increase over time.\16\
---------------------------------------------------------------------------

    \11\ In 2018, the Commission amended Rule 600, 605, and 606 of 
Regulation NMS (``the 2018 Rule 606 Amendments''). The 2018 Rule 606 
Amendments modified Rule 605 to require that the public order 
execution quality reports be kept publicly available for a period of 
three years. See Securities Exchange Act Release No. 84528 (Nov. 2, 
2018), 83 FR 58338 (Nov. 19, 2018) (``2018 Rule 606 Amendments 
Release'').
    \12\ For example, since the adoption of the Rule in 2000, the 
Commission has periodically revised certain of its NMS rules, 
including the adoption of Regulation NMS in 2005. See, e.g., 
Securities Exchange Act Release Nos. 51808 (June 9, 2005), 70 FR 
37496 (June 29, 2005) (``Regulation NMS Adopting Release''); and 
90610 (Dec. 9, 2020), 86 FR 18596 (Apr. 9, 2021) (``MDI Adopting 
Release'').
    \13\ For example, in January 2005, the New York Stock Exchange 
Inc. (``NYSE'') executed approximately 79.1% of the consolidated 
share volume in its listed stocks, compared to 25.1% in October 
2009. See Concept Release on Equity Market Structure, 75 FR 3594 
(Jan. 21, 2010) at 3595.
    \14\ As used in this release, the term ``individual investor'' 
will refer to natural persons that trade relatively infrequently for 
their own or closely related accounts.
    \15\ See, e.g., Caitlin McCabe, ``New Army of Individual 
Investors Flexes Its Muscle,'' The Wall Street Journal (Dec. 30, 
2020), available at <a href="https://www.wsj.com/articles/new-army-of-individual-investors-flexes-its-muscle-11609329600">https://www.wsj.com/articles/new-army-of-individual-investors-flexes-its-muscle-11609329600</a>.
    \16\ See MDI Adopting Release, 86 FR at 18606-07 (citing 
Securities Exchange Act Release No. 88216 (Feb. 14, 2020), 85 FR 
16726, 16739 (Mar. 24, 2020) (``MDI Proposing Release'') (stating 
that ``between 2004 and 2019, the average price of a stock in the 
Dow Jones Industrial Average nearly quadrupled'')).
---------------------------------------------------------------------------

    The Commission continues to believe that facilitating the ability 
of the public to compare and evaluate execution quality among different 
market centers is an effective means of reconciling the need to promote 
both vigorous price competition and fair competition among market 
centers. Providing increased visibility into the execution quality of 
larger broker-dealers would similarly encourage competition among 
market participants. It is the Commission's task continually to monitor 
market conditions and competitive forces and to evaluate whether the 
structure of the national market system as it evolves is achieving its 
Exchange Act objectives.\17\ Section 11A of the Exchange Act \18\ 
grants the Commission authority to promulgate rules necessary or 
appropriate to assure the fairness and usefulness of information on 
securities

[[Page 3788]]

transactions \19\ and to assure that broker-dealers transmit and direct 
orders for the purchase or sale of qualified securities in a manner 
consistent with the establishment and operation of a national market 
system.\20\ Through the proposed updates to Rule 605, the Commission 
seeks to promote increased transparency of order execution quality, 
increase the information available to investors, and help to promote 
competition among market centers and broker-dealers, while ameliorating 
the potentially adverse effects of fragmentation on efficiency, price 
transparency, best execution of investor orders, and order 
interaction.\21\

II. Current Reporting of Execution Quality Statistics

A. Adoption of Rule 11Ac1-5

    When the Commission adopted Rule 11Ac1-5, which was later re-
designated as Rule 605, in 2000, there was little publicly available 
information to enable investors to compare and evaluate execution 
quality among different market centers.\22\ The Commission proposed and 
adopted Rule 11Ac1-5 together with Rule 11Ac1-6, which was later re-
designated as Rule 606, requiring broker-dealers to disclose the 
identity of market centers to which they route orders on behalf of 
customers. When adopting these rules, the Commission stated that, taken 
together, they should significantly improve the opportunity for 
investors to evaluate what happens to their orders after they submit 
them to a broker-dealer for execution.\23\ The Commission reasoned that 
competitive forces could then be brought to bear on broker-dealers both 
with respect to the explicit trading costs associated with brokerage 
commissions and the implicit trading costs associated with execution 
quality.\24\ Rule 11Ac1-5 was intended to remedy an absence of public 
information about how broker-dealers responded to trade-offs between 
price and other factors, such as speed or reliability, and establish a 
baseline level of disclosure in order to facilitate cross-market 
comparisons of execution quality.\25\
---------------------------------------------------------------------------

    \22\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75416. 
For clarity, when this release discusses the adoption of Rule 605, 
it is referring to the Adopting Release, supra note 5.
    \23\ See id. at 75414.
    \24\ See id. at 75419. Although it is difficult to isolate the 
effects of the Rule given the evolution of the equity markets over 
time, one academic study examining the introduction of Rule 605 
found that the routing of marketable order flow by broker-dealers 
became more sensitive to changes in execution quality across market 
centers after Rule 605 reports became available. See Ekkehart 
Boehmer, Robert Jennings & Li Wei, Public Disclosure and Private 
Decisions: Equity Market Execution Quality and Order Routing, 20 
Rev. Fin. Stud. 315 (2007) (``Boehmer et al.''). Another study 
attributed a significant decline in effective and quoted spreads 
following the implementation of Rule 605 to an increase in 
competition between market centers, who improved the execution 
quality that they offered in order to attract more order flow. See 
Xin Zhao & Kee H. Chung, Information Disclosure and Market Quality: 
The Effect of SEC Rule 605 on Trading Costs, 42 J. Fin. Quantitative 
Analysis, 657 (Sept. 2007) (``Zhao & Chung'').
    \25\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75418, 
75419. Data obtained from Rule 605 reports are used by the third 
parties including academics and the financial press to study a 
variety of topics related to execution quality, including liquidity 
measurement, exchange competition, zero commission trading, and 
broker-dealer execution quality. See infra notes 545-547 and 
accompanying text.
---------------------------------------------------------------------------

B. Scope and Content of Rule 605

1. Scope
    Currently, Rule 605 requires market centers to make available, on a 
monthly basis, standardized information concerning execution quality 
for covered orders in NMS stocks that they received for execution. 
Market centers must provide specified measures of execution quality, 
including effective spread, average amount of price improvement, number 
of shares executed, and speed of execution.\26\
---------------------------------------------------------------------------

    \26\ See 17 CFR 242.605.
---------------------------------------------------------------------------

(a) Market Centers
    Regulation NMS defines the term ``market center'' to mean any 
exchange market maker,\27\ OTC market maker,\28\ ATS,\29\ national 
securities exchange,\30\ or national securities association.\31\ This 
definition was intended to cover entities that hold themselves out as 
willing to accept and execute orders in NMS securities.\32\ Further, a 
market center must report on orders that it ``received for execution 
from any person,'' which was intended to assign the disclosure 
obligation to an entity that controls whether and when an order will be 
executed.\33\
---------------------------------------------------------------------------

    \27\ ``Exchange market maker'' means any member of a national 
securities exchange that is registered as a specialist or market 
maker pursuant to the rules of such exchange. See 17 CFR 
242.600(b)(32).
    \28\ ``OTC market maker'' means any dealer that holds itself out 
as being willing to buy from and sell to its customers, or others, 
in the United States, an NMS stock for its own account on a regular 
or continuous basis otherwise than on a national securities exchange 
in amounts of less than a block size. See 17 CFR 242.600(b)(64).
    \29\ ``Alternative trading system'' or ``ATS'' means any 
organization, association, person, group of persons, or system: (1) 
That constitutes, maintains, or provides a market place or 
facilities for bringing together purchasers and sellers of 
securities or for otherwise performing with respect to securities 
the functions commonly performed by a stock exchange within the 
meaning of 17 CFR 240.3b-16; and (2) That does not: (i) Set rules 
governing the conduct of subscribers other than the conduct of such 
subscribers' trading on such organization, association, person, 
group of persons, or system; or (ii) Discipline subscribers other 
than by exclusion from trading. See 17 CFR 242.300(a). See also 17 
CFR 242.600(b)(4) (stating that ``alternative trading system'' has 
the meaning provided in 17 CFR 242.300(a)).
    \30\ ``National securities exchange'' means any exchange 
registered pursuant to section 6 of the Exchange Act. See 17 CFR 
242.600(b)(53).
    \31\ See 17 CFR 242.600(b)(46). ``National securities 
association'' means any association of brokers and dealers 
registered pursuant to section 15A of the Exchange Act. See 17 CFR 
242.600(b)(52).
    \32\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75421.
    \33\ See id.
---------------------------------------------------------------------------

    In many instances, broker-dealers accept orders from customers for 
execution and then route these customer orders to various execution 
venues, but do not execute customer orders directly. These broker-
dealers generally do not fall within the definition of ``market 
center'' and therefore fall outside of the scope of Rule 605's 
reporting requirements.\34\
---------------------------------------------------------------------------

    \34\ See, e.g., 17 CFR 242.605(a) (monthly electronic reports by 
market centers). In some instances, broker-dealers accept orders 
from customers for execution and execute a small portion of their 
order flow internally (e.g., fractional share orders), and therefore 
would fall within the definition of ``market center'' in Rule 
600(b)(46) with respect to the portion of their order flow for which 
they hold themselves out as being willing to buy or sell for their 
own account on a regular or continuous basis. However, if, for 
example, they only act as a market center for orders smaller than 
100 shares, then these market centers would not be required to 
prepare Rule 605 reports currently because the portion of their 
order flow for which they act as a market center would include only 
orders that fall below the smallest order size category (i.e., 100 
to 499 shares). See 17 CFR 242.600(b)(defining ``categorized by 
order size''); 17 CFR 242.605)(a)(1) (stating that a market center's 
monthly report ``shall be categorized by security, order type, and 
order size'').
---------------------------------------------------------------------------

(b) Covered Orders
    The covered order definition is limited by several conditions and 
exclusions in order to include those orders that provide a basis for 
meaningful and comparable statistical measures of execution quality. A 
``covered order'' is defined to include any market order or any limit 
order (including immediate-or-cancel orders) received by a market 
center during regular trading hours at a time when the national best 
bid and national best offer is being disseminated, and, if executed, is 
executed during regular trading hours.\35\ This definition serves two 
purposes: (1) because the nature and execution quality for regular and 
after-hours trading differs, it avoids blending statistics for orders 
executed after-hours with those executed during the regular

[[Page 3789]]

trading day; and (2) because many of the statistical measures included 
in the rule rely on the availability of the national best bid and offer 
(``NBBO'') at the time of order receipt, it excludes orders for which 
execution quality metrics could not be calculated.
---------------------------------------------------------------------------

    \35\ See 17 CFR 242.600(b)(22).
---------------------------------------------------------------------------

    Covered orders do not include any orders for which the customer 
requests special handling, which include, but are not limited to, 
market on open and market on close orders, stop orders, all or none 
orders, and ``not held'' orders.\36\ The Commission reasoned that 
special handling instructions could skew general execution quality 
measures.\37\
---------------------------------------------------------------------------

    \36\ See id. Generally, a ``not held'' order provides the 
broker-dealer with price and time discretion in handling the order, 
whereas a broker-dealer must attempt to execute a ``held'' order 
immediately. See 2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 
19, 2018) at 58340. As a general matter, if a customer submits an 
order for an NMS stock to its broker-dealer, whether it be for a 
fractional share, whole shares, or whole shares with a fractional 
share component, and the customer reasonably expects its broker-
dealer to attempt to execute such order immediately, then the 
broker-dealer generally should categorize the order as a held order.
    \37\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75421.
---------------------------------------------------------------------------

2. Required Information
    Rule 605 reports contain a number of execution quality metrics for 
covered orders, including statistics for all NMLOs with limit prices 
within ten cents of the NBBO at the time of order receipt as well as 
separate statistics for market orders and marketable limit orders. 
Under the Rule, the information is categorized by (1) individual 
security,\38\ (2) one of five order types,\39\ and (3) one of four 
order sizes.\40\ These categories provide users flexibility in 
determining how to summarize and analyze the information.\41\
---------------------------------------------------------------------------

    \38\ See 17 CFR 242.605(a)(1).
    \39\ See id. ``Categorized by order type'' refers to 
categorization by whether an order is a market order, a marketable 
limit order, an inside-the-quote limit order, an at-the-quote limit 
order, or a near-the-quote limit order. See 17 CFR 242.600(b)(14).
    \40\ See 17 CFR 242.605(a)(1). The current size categories are: 
100 to 499 shares; 500 to 1999 shares; 2000 to 4999 shares, and 5000 
or greater shares. See 17 CFR 242.600(b)(11). On June 22, 2001, the 
Commission granted exemptive relief to any order with a size of 
10,000 shares or greater, reasoning that the exclusion of very large 
orders would help assure greater comparability of statistics in the 
largest size category of 5,000 or greater shares. See Letter from 
Annette L. Nazareth, Director, Division of Market Regulation to 
Darla C. Stuckey, Assistant Secretary, NYSE, dated June 22, 2001 
(``Large Order Exemptive Letter'').
    \41\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75417. 
For instance, a user could analyze execution quality for a group of 
securities and by size and order type.
---------------------------------------------------------------------------

    Within each of the three categories, the reports are required to 
include statistics about the total number of orders submitted as well 
as the total number of shares submitted, shares cancelled prior to 
execution, shares executed at the receiving market center, shares 
executed at another venue, shares executed within different time-to-
execution buckets, and average realized spread.\42\ For market and 
marketable limit orders, the reports also must include average 
effective spread; number of shares executed better than the quote, at 
the quote, or outside the quote; average time to execution when 
executed better than the quote, at the quote, or outside the quote; as 
well as average dollar amount per share that orders were executed 
better than the quote or outside the quote.\43\ In addition, time of 
order execution and time of order receipt are required to be measured 
to the nearest second.\44\
---------------------------------------------------------------------------

    \42\ See 17 CFR 242.605(a)(1)(i).
    \43\ See 17 CFR 242.605(a)(1)(ii).
    \44\ See 17 CFR 242.600(b)(91), (92).
---------------------------------------------------------------------------

    The categorization by order type does not currently include away-
from-the-quote NMLOs, i.e., those orders with a limit price more than 
ten cents away from the NBBO. In proposing to exclude these orders in 
2000, the Commission indicated that the execution quality statistics 
for these types of orders may be less meaningful because execution of 
these types of orders may be more dependent on the extent to which the 
orders' limit prices were outside the consolidated best bid and offer 
(``BBO'') and price movement in the market than on their handling by 
the market center.\45\
---------------------------------------------------------------------------

    \45\ See Securities Exchange Act Release No. 43084 (July 28, 
2000), 65 FR 48406, 48414 (Aug. 8, 2000) (File No. S7-16-00) 
(Disclosure of Order Execution and Routing Practices) (``Proposing 
Release'') (stating that the Commission preliminarily believed that 
the rule's statistical measures (e.g., fill rates and speed of 
execution) for this type of order may be less meaningful because 
they would be more dependent on the extent to which the orders' 
limit prices were outside the consolidated BBO (and movements in 
market prices) than on their handling by a market center).
---------------------------------------------------------------------------

3. Procedures for Making Reports Available to the Public
    The Rule 605 NMS Plan establishes procedures for market centers to 
make data available to the public in a uniform, readily accessible, and 
usable electronic form.\46\ The Plan also requires market centers to 
post their monthly reports on an internet website that is free of 
charge and readily accessible to the public.\47\ Generally, reports are 
posted on market centers' own websites; however, they may be posted on 
a third-party vendor site if a market center uses a vendor to prepare 
its reports.\48\ In addition, formatting for Rule 605 data is governed 
by the Plan. Among other things, the Plan sets forth the file type and 
structure of the reports and the order and format of fields, yielding 
reports that are structured and machine-readable.\49\
---------------------------------------------------------------------------

    \46\ See 17 CFR 242.605(a)(2) and Securities and Exchange 
Commission File No. 4-518 (National Market System Plan Establishing 
Procedures Under Rule 605 of Regulation NMS) (``Rule 605 NMS Plan'' 
or ``Plan''). See also Securities Exchange Act Release No. 44177 
(Apr. 12, 2001), 66 FR 19814 (Apr. 17, 2001) (order approving the 
Plan).
    \47\ Currently, the parties to the Plan are the 16 registered 
national securities exchanges trading NMS stocks and 1 national 
securities association (the ``Participants''). Although not all 
market centers are Participants, the Participants are required to 
enforce compliance with the terms of the Plan by their members and 
person associated with their members. See 17 CFR 242.608(c). Market 
centers that are not Participants must make arrangements with a 
Participant to act as their ``Designated Participant.'' See Plan at 
IV. Each market center must notify its Designated Participant of the 
website where its reports may be downloaded, and each Designated 
Participant must maintain a comprehensive list of links for all 
market centers for which it functions as a Designated Participant. 
See Plan at IV, VIII(c).
    \48\ See Plan at n.3.
    \49\ See id. at 2 (``Section V . . . provides that market center 
files must be in standard, pipe-delimited ASCII format'').
---------------------------------------------------------------------------

C. Other Relevant Rules

    Rule 606 reports address order handling information and Rule 606's 
reporting requirements differ for held orders versus not held orders. 
With respect to held orders, Rule 606(a)(1) requires broker-dealers to 
produce quarterly public reports regarding their routing of non-
directed orders \50\ in NMS stocks that are submitted on a held basis. 
These reports must identify certain regularly-used venues to which the 
broker-dealer routed non-directed orders for execution and provide data 
on the percentage of orders routed to each venue.\51\ These reports 
also must provide information, for each venue identified, about the 
payment relationship between the broker-dealer and the venue, including 
any payments made by a venue to a broker-dealer for the right to trade 
with its customer order flow (i.e., payment for order flow or ``PFOF'') 
or rebates,\52\ and a description of the material aspects of the 
broker-dealer's relationship with the venue and the terms of 
arrangements that may influence a broker-dealer's order routing

[[Page 3790]]

decision.\53\ In addition, Rule 606(b)(1) requires broker-dealers to 
provide to their customers, upon request, reports that include high-
level customer-specific order routing information, such as the identity 
of the venues to which the customer orders were routed for execution in 
the prior six months and the time of the transactions, if any, that 
resulted from such orders.\54\ For orders submitted on a held basis, 
the reports required by Rule 606 do not contain any execution quality 
information. However, a customer of a reporting broker-dealer may 
access the execution quality reports produced pursuant to Rule 605 by 
each venue identified as a routing destination in the broker-dealer's 
Rule 606 reports, to the extent that venue is a market center.\55\
---------------------------------------------------------------------------

    \50\ A ``non-directed order'' means any order from a customer 
other than a directed order. See 17 CFR 242.600(b)(56). A ``directed 
order'' means an order from a customer that the customer 
specifically instructed the broker or dealer to route to a 
particular venue for execution. See 17 CFR 242.600(b)(27).
    \51\ See 17 CFR 242.606(a)(1)(ii) (stating that each section in 
the required report shall include the identity of the ten venues to 
which the largest number of total non-directed orders for the 
section were routed for execution and of any venue to which five 
percent or more of non-directed orders were routed).
    \52\ See 17 CFR 242.606(a)(1)(iii).
    \53\ See 17 CFR 242.606(a)(1)(iv).
    \54\ See 17 CFR 242.606(b)(1).
    \55\ See supra note 23 and accompanying text.
---------------------------------------------------------------------------

    In contrast, Rule 606 requires broker-dealers to produce reports 
that provide detail regarding execution quality in connection with not 
held orders, which are typically used by institutional investors.\56\ 
Specifically, Rule 606(b)(3) requires broker-dealers to produce reports 
pertaining to order routing upon the request of a customer that places, 
directly or indirectly, one or more orders in NMS stocks that are 
submitted on a not held basis.\57\ These customer-specific reports 
generally must include detailed information, by venue, including 
metrics pertaining to the broker-dealer's routing of the customer's 
orders and the execution of such orders.\58\ In particular, the venue-
by-venue order execution information must include aggregated metrics 
such as fill rate, percentage of shares executed at the midpoint, and 
percentages of total shares executed that were priced on the side of 
the spread more favorable to the order and on the side of the spread 
less favorable to the order.\59\
---------------------------------------------------------------------------

    \56\ See 2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 19, 
2018) at 58345 (stating that by using the not held order 
distinction, Rule 606(b)(3) as adopted will likely result in more 
Rule 606(b)(3) disclosures for order flow that is typically 
characteristic of institutional customers--not retail customers--and 
will likely cover all or nearly all of the institutional order 
flow). In contrast, held orders are typically used by individual 
investors. See, e.g., id. at 58372 (stating that retail investors' 
orders are typically submitted on a held basis and are typically 
smaller in size).
    \57\ See 17 CFR 240.606(b)(3).
    \58\ See 17 CFR 240.606(b)(3).
    \59\ See 17 CFR 240.606(b)(3)(ii).
---------------------------------------------------------------------------

    Current Rule 606 reflects significant changes that were made in the 
2018 Rule 606 Amendments.\60\ When adopting the 2018 Rule 606 
Amendments, the Commission identified intensified competition for 
customer orders, the rise in the number of trading centers, and the 
introduction of new fee models for execution services as the main 
concerns with held orders for NMS stocks that it sought to address with 
the proposal.\61\ The Commission stated that the more prevalent use of 
financial inducements to attract order flow from broker-dealers that 
handle retail investor orders created new, and in many cases 
significant, potential conflicts of interests for these broker-
dealers.\62\ Further, the Commission stated that enhanced public 
disclosures for held orders should focus on providing more detailed 
information regarding these financial inducements, as opposed to the 
different information geared towards not held orders from customers 
that is set forth in Rule 606(b)(3).\63\ Therefore, the Commission 
adopted enhanced public disclosures pursuant to Rule 606(a)(1) that 
focused on increased transparency for the financial inducements that 
broker-dealers face when determining where to route held order 
flow.\64\ The Commission stated that this enhancement would allow 
customers to better assess the nature and quality of broker-dealers' 
order handling services, including the potential for broker-dealer 
conflicts of interest, and would also benefit customers to the extent 
that broker-dealers were spurred to compete further by providing 
enhanced order routing services and better execution quality.\65\
---------------------------------------------------------------------------

    \60\ See generally 2018 Rule 606 Amendments Release.
    \61\ See 2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 19, 
2018) at 58372.
    \62\ See id.
    \63\ See id. The Commission also considered but did not adopt an 
aspect of the proposal that would have required broker-dealers to 
make publicly available a report that would have aggregated Rule 
606(b)(3) order handling information pertaining to not held orders. 
See id. at 58369-70. The Commission stated that its decision stemmed 
from fundamental differences between held order flow and not held 
order flow, because held orders are typically non-directed orders 
with no specific order-handling instructions for the broker-dealer. 
See id. at 58371 (stating that held order flow is handled similarly 
by broker-dealers--held orders are generally small orders that are 
internalized or sent to OTC market makers if marketable or fully 
executed on a single trading center if not marketable). The 
Commission further stated that, by contrast, not held order flow is 
diverse and customers may provide specific order handling 
instructions to their broker-dealers, limit the order handling 
discretion of their broker-dealers, or have specific needs that 
impact the broker-dealers' handling of these orders. See id. 
Therefore, the Commission concluded that the disparate behavior of 
customers when using not held orders limited the potential ability 
for customers and broker-dealers to use aggregated Rule 606(b)(3) 
order handling information to better understand broker-dealers' 
routing behavior or compare broker-dealers' order routing 
performance. See id.
    \64\ See 2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 19, 
2018) at 58373.
    \65\ See id. In comparison, with respect to the addition of 
customer-specific order-handling disclosures in Rule 606(b)(3), the 
Commission stated that these disclosures are particularly suited to 
customers that submit not held NMS stock orders because the 
disclosures set forth detailed order handling information that is 
useful in evaluating how broker-dealers exercise the discretion 
attendant to not held orders and, in the process, carry out their 
best execution obligations and manage the potential for information 
leakage and conflicts of interest. See id. at 58344. As part of the 
2018 Rule 606 Amendments, the Commission added Rule 606(b)(3) to 
require broker-dealers to make detailed, customer-specific order 
handling disclosures available to institutional customers, in 
particular, who previously were not entitled to disclosures under 
the rule for their order flow, or were entitled to disclosures that 
had become inadequate in a highly automated and more complex market. 
See id.
---------------------------------------------------------------------------

    At the time of the 2018 Rule 606 Amendments, the Commission 
considered suggestions from the Equity Market Structure Advisory 
Committee (``EMSAC'') and other commenters that the Commission include 
more or different execution quality statistics in the required 
disclosures.\66\ But the Commission stated that the limited 
modifications to Rule 606(a) that it was adopting were reasonably 
designed to further the goal of enhancing transparency regarding 
broker-dealers' order routing practices and customers' ability to 
assess the quality of those practices, and that the suggested execution 
quality statistics were not necessary to achieve that goal.\67\ 
However, the Commission noted that its determination not to adopt the 
additional specific disclosures was not an indication that the 
Commission had formed a decision on the validity or usefulness of the 
suggested execution quality statistics.\68\
---------------------------------------------------------------------------

    \66\ See id. at 58379. See also EMSAC III at 2-3 (suggesting 
that the Commission modify the enhancements to Rule 606 to include, 
among other things, execution quality statistics by routing 
destination).
    \67\ See 2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 19, 
2018) at 58379.
    \68\ See id.
---------------------------------------------------------------------------

    Separately, each broker-dealer has a legal duty to seek to obtain 
best execution of customer orders.\69\ The

[[Page 3791]]

duty of best execution requires broker-dealers to execute customers' 
trades at the most favorable terms reasonably available under the 
circumstances.\70\ When adopting Rule 605 and Rule 606, the Commission 
stated that these rules do not address and therefore do not change the 
existing legal standards that govern a broker-dealer's duty of best 
execution.\71\ The Commission recognized that the information contained 
in the Rule 605 reports (and Rule 606 reports) will not, by itself, be 
sufficient to support conclusions regarding a broker-dealer's 
compliance with its legal responsibility to obtain the best execution 
of customer orders.\72\ As the Commission stated, any such conclusions 
would require a more in-depth analysis of the broker-dealer's order 
routing practices than will be available from the disclosures required 
by the rules.\73\
---------------------------------------------------------------------------

    \69\ See, e.g., Regulation NMS Adopting Release, 70 FR at 37537; 
Newton v. Merrill, Lynch, Pierce, Fenner & Smith, Inc., 135 F.3d 
266, 269-70, 274 (3d Cir.), cert. denied, 525 U.S. 811 (1998); 
Certain Market Making Activities on Nasdaq, Securities Exchange Act 
Release No. 40900, 53 SEC 1150, 1162 (1999) (settled case) (citing 
Sinclair v. SEC, 444 F.2d 399 (2d Cir. 1971); Arleen Hughes, 27 SEC 
629, 636 (1948), aff'd sub nom. Hughes v. SEC, 174 F.2d 969 (D.C. 
Cir. 1949)). In addition, the Commission is separately proposing a 
rule concerning broker-dealers' duty of best execution. See 
Securities Exchange Act Release No. 96496 (Dec. 14, 2022) (File No. 
S7-32-22) (Regulation Best Execution). The Commission encourages 
commenters to review that proposal to determine whether it might 
affect their comments on this proposing release.
    \70\ See Regulation NMS Adopting Release, 70 FR 37496 (Jun. 29, 
2005) at 37538 (referring to the best reasonably available price and 
citing Newton, 135 F.3d at 266, 269-70, 274). Newton also specified 
certain other factors relevant to best execution--order size, 
trading characteristics of the security, speed of execution, 
clearing costs, and the cost and difficulty of executing an order in 
a particular market. See Newton, 135 F.3d at 270 n.2.
    \71\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75420.
    \72\ See id.
    \73\ See id. For example, the execution quality statistics 
included in Rule 605 do not encompass every factor that may be 
relevant in determining whether a broker-dealer has obtained best 
execution, and the statistics in a market center's reports typically 
will reflect orders received from a number of different routing 
broker-dealers. See id. See also infra notes 564-565 and 
accompanying text for discussion of an investment adviser's 
fiduciary duty, including the duty to seek best execution of a 
client's transactions where the investment adviser has the 
responsibility to select broker-dealers to execute client trades.
---------------------------------------------------------------------------

D. Overview of Need for Modernization

    The U.S. equity markets have evolved significantly since the 
Commission adopted the Rule in 2000. For instance, the equities markets 
have become increasingly fragmented, as both the market shares of 
individual national securities exchanges became less concentrated and 
an increased percentage of order flow moved off-exchange. In 2000, 
there were 9 registered national securities exchanges and one 
registered national securities association.\74\ A large proportion of 
the order flow in listed equity securities was routed to a few, mostly 
manual, trading centers,\75\ and the primary listing exchanges retained 
a high percentage of the order flow for exchange-listed equities.\76\
---------------------------------------------------------------------------

    \74\ See Securities and Exchange Commission, Annual Report for 
fiscal year 2000, at 38 available at <a href="https://www.sec.gov/pdf/annrep00/ar00full.pdf">https://www.sec.gov/pdf/annrep00/ar00full.pdf</a>.
    \75\ See Securities Exchange Act Release No. 78309 (July 13, 
2016), 81 FR 49432, 49436 (July 27, 2016) (``Rule 606 Proposing 
Release''); Fragmentation Release, 65 FR 10577 (Feb. 28, 2000) at 
10579-80.
    \76\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75415 
(stating that in September 2000, for example, NYSE accounted for 
83.3% of the share volume in NYSE equities and that the American 
Stock Exchange, LLC (``Amex'') accounted for 69.9% of share volume 
in Amex equities). See also Concept Release on Equity Market 
Structure, 75 FR 3594 (Jan. 21, 2010) at 3595 (stating that in 
January 2005, NYSE executed approximately 79.1% of the consolidated 
share volume in its listed stocks, as compared to 25.1% in October 
2009). In addition, NYSE-listed stocks were traded primarily on the 
floor of the NYSE in a manual fashion until October 2006, at which 
time NYSE began to offer fully automated access to its displayed 
quotations. See Concept Release on Equity Market Structure, 75 FR 
3594 (Jan. 21, 2010) at 3594-95. However, stocks traded on the 
NASDAQ Stock Market LLC (``NASDAQ''), which in 2000 was owned and 
operated by a national securities association, were already trading 
in a highly automated fashion at many different trading centers. See 
id. at 3595; Fragmentation Release, 65 FR 10577 (Feb. 28, 2000) at 
10580.
---------------------------------------------------------------------------

    In contrast, trading in the U.S. equity markets today is highly 
automated and spread among different types of trading centers, allowing 
even more choices about where orders may be routed. The types of 
trading centers that currently trade NMS stocks are: (1) national 
securities exchanges operating SRO trading facilities; \77\ (2) ATSs 
that trade NMS stocks (``NMS Stock ATSs''); \78\ (3) exchange market 
makers; (4) wholesalers; \79\ and (5) any other broker-dealer that 
executes orders internally by trading as principal or crossing orders 
as agent.\80\ In the first quarter of 2022, NMS stocks were traded on 
16 national securities exchanges, and off-exchange at 32 NMS Stock ATSs 
and at over 230 other FINRA members.\81\ National securities exchanges 
executed approximately 60% of NMS share volume.\82\ The majority of 
off-exchange volume was executed by wholesalers, who executed almost 
one quarter of total volume (23.9%) and about 60% of off-exchange 
volume.\83\ Some OTC market makers, such as wholesalers, operate SDPs 
through which they execute institutional orders in NMS stocks against 
their own inventory.\84\
---------------------------------------------------------------------------

    \77\ See 17 CFR 242.600(b)(89) (defining ``SRO trading 
facility'' as, among other things, a facility operated by a national 
securities exchange that executes orders in a security).
    \78\ An ``NMS Stock ATS'' as used in this release is an ATS that 
has filed an effective Form ATS-N with the Commission.
    \79\ The term ``wholesaler'' is not defined in Regulation NMS, 
but is commonly used to refer to an OTC market maker that seeks to 
attract orders from broker-dealers that service the accounts of a 
large number of individual investors.
    \80\ See 15 U.S.C. 78c(a)(4)(A) (defining ``broker'' generally 
as any person engaged in the business of effecting transactions in 
securities for the account of others); 15 U.S.C. 78c(a)(5)(A) 
(defining ``dealer'' generally as any person engaged in the business 
of buying and selling securities for such person's own account 
through a broker or otherwise). The term ``broker-dealer'' is used 
in this release to encompass all brokers, all dealers, and firms 
that are both brokers and dealers. See also 17 CFR 242.600(b)(95) 
(defining ``trading center'').
    \81\ See infra note 766 and accompanying text; Table 7.
    \82\ See infra note 767 and accompanying text; Table 7.
    \83\ See infra Table 7.
    \84\ See infra note 768 and accompanying text.
---------------------------------------------------------------------------

    Broker-dealers that primarily service the accounts of individual 
investors (referred to in this release as ``retail brokers'') often 
route the marketable orders of individual investors in NMS stocks to 
wholesalers.\85\ The primary business model of wholesalers is to trade 
internally as principal with individual investor orders. They do not 
publicly display or otherwise reveal the prices at which they are 
willing to trade internally as a means to attract individual investor 
orders from broker-dealers. Moreover, it is generally more profitable 
for liquidity providers such as wholesalers to execute against orders 
with lower adverse selection risk because of the reduced risk that 
prices will move against the liquidity provider.\86\ Wholesalers may 
provide different execution quality to different broker-dealers, 
depending on factors including the level of adverse selection risk of 
their order flow.\87\
---------------------------------------------------------------------------

    \85\ There are six wholesalers that internalize the majority of 
individual investors' marketable orders. See infra note 766 and 
accompanying text.
    \86\ See infra note 608 and accompanying text.
    \87\ Analysis of Consolidated Audit Trail (``CAT'') data from 
the first five months of 2022 found that wholesalers provide 
different execution quality to different retail brokers, and in 
particular that broker-dealers with higher adverse selection risk 
systematically receive higher effective spreads and lower price 
improvement than broker-dealers with lower adverse selection risk. 
See infra notes 609-613 and accompanying text; Table 3. For further 
discussion of differences in execution quality across broker-
dealers, see infra section VII.C.1.a).
---------------------------------------------------------------------------

    Some retail brokers may face conflicts of interest when making 
order routing decisions, including whether to route to a particular 
wholesaler.\88\ For example, broker-dealers could face conflicts of 
interest when making routing decisions due to their own affiliation 
with market centers (e.g., if the broker-dealer operates its own ATS), 
from the presence of liquidity fees and rebates on some market centers, 
or from payments that some retail brokers receive from wholesalers to 
attract the order flow of

[[Page 3792]]

their individual investor customers (PFOF).\89\
---------------------------------------------------------------------------

    \88\ See infra section VII.C.3.a)(2). See also 2018 Rule 606 
Amendments Release, 83 FR 58338 (Nov. 19, 2018) at 58372 (stating 
that financial inducements to attract order flow from broker-dealers 
that handle retail investor orders have become more prevalent and 
for some broker-dealers such inducements may be a significant source 
of revenue); supra note 62 and accompanying text (stating that these 
financial inducements have created new, and in many cases 
significant, potential conflicts of interest for these broker-
dealers).
    \89\ See infra notes 759-762 and accompanying text.
---------------------------------------------------------------------------

    The Commission is concerned that variations in execution quality 
across broker-dealers may be difficult to assess using current Rule 605 
and Rule 606 reports. In particular, broker-dealers that route customer 
orders externally, rather than executing customer orders internally, 
are not required to prepare Rule 605 reports because they do not meet 
the definition of market center. Customers of a broker-dealer can use 
Rule 606 reports to identify market centers to which the broker-dealer 
routes, and then access those market centers' Rule 605 reports to 
review the execution quality that the market center provides to all 
orders that the market center received for execution. However, to the 
extent that the market center may provide different execution quality 
to orders based on different order routing arrangements with different 
broker-dealers, current Rule 605 and 606 do not require reports that 
provide investors with a way to assess these differences.
    In addition, developments in trading, including the increased speed 
of trading, further necessitate proposing updates to the Rule. Average 
stock prices have continued to increase over time,\90\ and odd-lots 
\91\ and fractional shares \92\ continue to trade with increasing 
frequency. Similarly, odd-lot quotes in higher-priced stocks continue 
to offer prices that are frequently better than the round lot NBBO for 
these stocks,\93\ and this better-priced odd-lot liquidity is 
distributed across multiple price levels.\94\ In addition, odd-lot 
rates have increased among lower priced stocks.\95\ Because current 
Rule 605 size categories exclude orders smaller than 100 shares, a 
significant proportion of market activity is currently excluded.\96\ An 
analysis of Rule 605 data shows that Rule 605 coverage has likely 
declined in the decades since the initial adoption of Rule 605.\97\ 
Further, because order size categories are tied to the number of 
shares, the categories may group orders of very different notional 
values, which may complicate comparisons of aggregate execution 
quality. Finally, the speed of the market has increased exponentially 
since 2000,\98\ rendering the Rule's current one-second timestamp 
conventions less meaningful.

    \91\ See MDI Adopting Release, 85 FR 18612 (Apr. 2, 2020) at 
18616 (describing analyses included in the MDI Adopting Release 
confirming observations made in the MDI Proposing Release that a 
significant proportion of quotation and trading activity occurs in 
odd-lots, particularly for frequently traded, high-priced stocks). 
Analysis using the NYSE Trade and Quote database (obtained via 
Wharton Research Data Services (WRDS) (``TAQ data'' or ``NYSE TAQ 
data'') found that odd-lots increased from around 15% of trades in 
January 2014 to more than 55% of trades in March 2022. An analysis 
of data from the SEC's MIDAS analytics tool available at <a href="https://www.sec.gov/marketstructure/datavis.html#.YoPskqjMKUk">https://www.sec.gov/marketstructure/datavis.html#.YoPskqjMKUk</a> shows that, in 
Q1 2022, odd-lots made up 81.2% of on-exchange trades (40% of 
volume) for stocks in the highest price decile and 25% of on-
exchange trades (2.72% of volume) for stocks in the lowest price 
decile. See dataset ``Summary Metrics by Decile and Quartile'' 
available at <a href="https://www.sec.gov/marketstructure/downloads.html">https://www.sec.gov/marketstructure/downloads.html</a>.
    \92\ Analysis using CAT data for executed orders in March 2022 
found that an estimated 46.63 million originating orders with a 
fractional share component were eventually executed on- or off-
exchange. This represents approximately 2% of all executed orders 
and 14% of executed orders from individual accounts. Generally, 
accounts classified as ``individual'' in CAT are attributed to 
natural persons. See also infra note 647 and accompanying text.
    \93\ See MDI Adopting Release, 86 FR 18596 (Apr. 9, 2021) at 
18729. In addition, a recent academic working paper shows that odd-
lots offer better prices than the NBBO 18% of the time for bids and 
16% of the time for offers. This percentage increases monotonically 
in the stock price, for example, for bid prices, increasing from 5% 
for the group of lowest-price stocks in their sample, to 42% for the 
group of highest-priced stocks. See Robert P. Bartlett, Justin 
McCrary, and Maureen O'Hara, The Market Inside the Market: Odd-Lot 
Quotes (Feb. 1, 2022), available at SSRN: <a href="https://ssrn.com/abstract=4027099">https://ssrn.com/abstract=4027099</a> (``Bartlett, et al.''). See also Elliot Banks, BMLL 
Technologies, Inside the SIP and the Microstructure of Odd-Lot

18613 n.202 (describing analysis included in the MDI Adopting 
Release that examined quotation data for the week of May 22-29, 2020 
for stocks priced from $250.01 to $1000.00 and found that there is 
odd-lot interest priced better than the new round lot NBBO 28.49% of 
the time, and, in 48.49% of those cases, there are better priced 
odd-lots at multiple price levels).
    \95\ For example, odd-lot rates for corporate stock price 
deciles 1-3 (the lowest priced corporate stocks comprising 30% of 
all corporate stocks) have been higher on average in 2021 and June 
2022 (34%, 39%) as compared to 2019 and 2020 (26%, 29%). Similarly, 
exchange-traded products (``ETPs'') also exhibit higher average odd-
lot rates in price quartiles 1 and 2 (the lowest priced ETPs 
comprising 50% of all ETPs) on average in 2021 and June 2022 (26%, 
29%) compared to 2019 and 2020 (20%, 23%). See SEC market structure

accompanying text (estimating, based on analysis of Tick Size Pilot 
data, coverage of current Rule 605 reporting requirements).
    \97\ Analysis comparing one market center's volume (NYSE) to TAQ 
data shows that an estimated 50% of shares executed during regular 
market hours were included in Rule 605 reports as of February 2021, 
and shows that this number has been on a slightly downward trend 
since around mid-2012. See infra section VII.C.2.b) and infra Figure 
3.
    \98\ Analysis of data from the SEC's MIDAS analytics tool shows 
that the percent of on-exchange NMLOs that are fully executed within 
one millisecond (as a percentage of all fully executed on-exchange 
NMLOs) has increased from 2.1% in Q1 2012 to 10.3% in Q1 2022 for 
small cap stocks, and from 5.9% in Q1 2012 to 15.7% in Q1 2022 for 
large cap stocks. Further, in Q1 2022 more than half (51.6%) of 
NMLOs executed in less than one second in large market cap stocks.

E. EMSAC Recommendations, Petition for Rulemaking, and Other Comments

    The EMSAC \99\ as well as commenters responding to the Commission's 
Concept Release on Equity Market Structure \100\ and to the 2018 Rule 
606 Amendments,\101\ have recommended

[[Page 3793]]

that the Commission amend Rule 605 to modernize the Rule and increase 
the usefulness of available execution quality disclosures. In addition, 
one broker-dealer petitioned the Commission to make ``modest rule 
amendments'' to Rule 605 and further stated that ``[i]mproving these 
metrics is essential for a market participant to quantitatively and 
qualitatively assess whether any particular broker-dealer obtained the 
most favorable terms under the circumstances for customer orders.''

---------------------------------------------------------------------------

    The EMSAC and commenters generally support expanding the Rule's 
scope beyond market centers.\103\ In particular, in November 2016, the 
EMSAC recommended that the Commission ``[e]xpand the scope of Rule 605 
by requiring every broker-dealer to report with an exemption for 
broker[-]dealers with de minimis order flow, aligning the scope of Rule 
605 reporting with Rule 606.'' \104\ The EMSAC's recommendation 
acknowledged that there would be compliance and implementation costs 
associated with this expansion, but stated that the use of third-party 
vendors may mitigate some of these concerns.\105\ Further, the EMSAC's 
recommendation stated that having all broker-dealers provide Rule 605 
data would create an opportunity for market participants, academics, 
and the press to evaluate these statistics in a consistent manner.\106\
---------------------------------------------------------------------------

    \103\ See EMSAC III at 2; IHS Markit Letter at 2; Healthy 
Markets II at 2.

Issues Subcommittee).

    \106\ See id.
---------------------------------------------------------------------------

    When the EMSAC met to consider this recommendation, panelists 
provided some explanation of the gaps in current execution quality 
disclosures. One panelist stated that the current reporting regime 
``miss[es] important information about the overall execution quality of 
a covered order'' because Rule 605 reports only pertain to order 
routing handled by market centers.\107\ This panelist explained that 
orders are handled by smart order routers that may not be located 
within a market center, and the Rule 605 data does not capture price 
slippage or delays that may occur as these orders are received by 
multiple non-executing market centers or broker-dealers.\108\ Another 
panelist described the difficulties that he encountered when trying to 
compare the execution quality of brokers using data available under the 
existing rules.\109\ According to the panelist, he ``had to make very 
rough inferences about the brokers' executions because of the gaps in 
the disclosure requirements.'' \110\ Moreover, this panelist stated 
that one fundamental problem with making these inferences was that a 
market maker's average execution quality across all of its orders 
received from brokers may be better or worse than its execution quality 
with respect to a particular broker's order flow.\111\

0097:3-8 (Bill Alpert, Barron's) (stating that ``the only effective, 
objective way to use the available disclosures was to score each 
broker with a weighted sum of their order flow fractions from the 
routing reports and then weight those with the effective over quoted 
measures of the market makers that they were sending their orders 
to''); 0096:25-0097:3 (stating that some brokers voluntarily 
disclose execution quality information, but they use different 
information and so the information is not comparable).
    \111\ See EMSAC I at 0097:14-22 (Bill Alpert, Barron's). See 
also id. at 0096:18-22 (Bill Alpert, Barron's) (stating that 
``almost every broker'' claimed that the execution quality that it 
received at a particular market maker was above average). This 
panelist also argued, based on the introduction of voluntary 
disclosures regarding price improvement for odd-lot orders by a few 
brokers and market makers, that disclosure improves behavior. See 
id. at 0098:6-0099:9 (Bill Alpert, Barron's) (stating the price 
improvement on odd-lot orders improved within a year after voluntary 
disclosures started). See also id. at 0132:6-11 (Brad Katsuyama, 
IEX) (stating that improving disclosures leads to improved 
performance).
---------------------------------------------------------------------------

    One EMSAC committee member acknowledged that retail brokerage firms 
did not favor the recommendation to expand Rule 605 reporting to 
broker-dealers, and stated that these firms would argue that aggregate 
statistics are more important for retail investors, who they claim are 
not going to look at the Rule 605 reports.\112\ This committee member 
stated that the counter-argument to this position is that if everyone 
is preparing Rule 605 reports, it would be possible to do various types 
of aggregation using that data.\113\ When the EMSAC met later to 
approve the recommendation, one committee member stated that the goal 
is to make data publicly available so that ``experts can help people 
make better decisions'' and that different groups would turn the data 
into usable reports, so it is not necessary to scale back the 
disclosures for the consumer.\114\
---------------------------------------------------------------------------

    \112\ See id. at 0136:24-0137:7 (Manisha Kimmel, Thomson 
Reuters). But see id. at 0102:22-0103:2) (Frank Hatheway, NASDAQ) 
(``While individual retail investors generally don't review 605 
statistics themselves, . . . the existence of the reports appears to 
provide precisely the form of discipline that the Commission 
envisioned when it adopted Rule 605 and 606.'').
    \113\ See EMSAC I at 0137:7-10 (Manisha Kimmel, Thomson 
Reuters). See also Statement of Christopher Nagy, Healthy Markets 
Association, at 6 (suggesting that the Commission mandate reporting 
of some execution quality statistics for retail orders); Healthy 
Markets I at 5-6 (recommending that the Commission modify Rule 606 
to include select execution quality statistics from Rule 605 for 
each identified routing destination).
    \114\ EMSAC II at 0065:1-16 (Brad Katsuyama, IEX). But see id. 
at 0064:18-24 (Jamil Nazarali, Citadel) (stating that his firm's 
retail broker clients expressed concerns with the recommendation 
that Rule 606 include the execution quality of the market makers 
that they route to, because there is a lot of important criteria 
that goes into routing and the reports could be misleading).
---------------------------------------------------------------------------

    When the Commission solicited comment on the 2018 Rule 606 
Amendments, several commenters recommended that the Commission expand 
the required reporting of execution quality statistics to better cover 
retail investors.\115\ One commenter stated that the type of 
standardized execution statistics that several firms voluntarily 
publish on a quarterly basis measure the quality of trade executions on 
retail investor orders in exchange-listed stocks and help investors 
evaluate their particular retail brokerage firm.\116\ Another commenter 
stated that there is a ``fundamental flaw'' in the logic of Rule 605 
and Rule 606 because ``[t]he structure of the rules implicitly assumes

[[Page 3794]]

that execution quality is solely a function of the market center and 
that the brokerage firm has no impact on execution quality.'' \117\ 
According to this commenter, execution quality is a product of both the 
broker's skill and the quality of the market center's execution, and 
therefore requiring brokers to show where they route orders does not 
provide retail investors with useful information about the actual 
execution quality that their orders receive.\118\ Another commenter 
stated that even though most retail investors may not use the 
disclosures directly, disclosures provide indirect benefits by 
promoting competition and by facilitating use by third-party analysts 
and academic researchers that provide an in-depth review of the 
disclosures.\119\
---------------------------------------------------------------------------

    \115\ See Angel Letter at 3 (recommending that brokers should be 
required to provide execution quality statistics by providing 
information on individual trade confirmations and displaying summary 
statistics on their websites); Fidelity Letter at 7-8 (recommending 
that the Commission require brokers to make publicly available 
certain execution quality statistics); Healthy Markets I at 7, 11 
(recommending that execution quality metrics should be provided to 
retail customers); IHS Markit Letter at 2 (recommending that all 
brokers that receive client orders and subsequently route orders on 
behalf of the client should provide information on the execution 
quality received at each venue). See also Consumer Federation II at 
10; Financial Services Roundtable Letter at 4-5.

about this voluntary effort to provide aggregated execution quality 
statistics, see infra notes 450-451 and accompanying text. See also 
Consumer Federation II at 10 (stating that voluntary disclosures by 
several market participants show that such disclosures are possible, 
and undercut arguments that doing so is too costly or burdensome).
    \117\ Angel Letter at 3.
    \118\ See id. However, this commenter also stated that the Rule 
605 data on execution quality is too raw for most investors to 
interpret. See id. at 2. See also Consumer Federation II at 10 
(stating that the only way to assess whether customers are being 
best served by their broker-dealer's routing decisions is by 
requiring execution quality statistics); Financial Services 
Roundtable Letter at 4-5 (stating that currently Rule 605 reports 
require investors to draw an inference that they will achieve the 
same performance as the average order sent to that venue, and 
additional data would help an investor compare the execution quality 
that various broker-dealers obtain at a particular execution venue).
    \119\ See Consumer Federation II at 10. See also IHS Markit 
Letter at 29-30 (stating that large retail routing brokers use 
private, internal versions of Rule 605 reports to calculate 
execution quality metrics for different market centers, leading to 
significant improvement in execution quality statistics for covered 
orders, and that voluntary reporting of execution quality metrics 
has also improved execution quality).
---------------------------------------------------------------------------

    One market participant, in a letter recommending that the 
Commission require broker-dealers to publish monthly cost of execution 
statistics, stated that Rule 605 and Rule 606 statistics published by 
market centers and broker-dealers do not provide a means for customers 
to judge how their brokers have performed with respect to keeping 
commissions low without adversely affecting execution quality.\120\ 
This commenter further remarked that matching a broker's routing 
statistics up with a receiving market center's execution quality 
statistics is ``essentially impossible.'' \121\
---------------------------------------------------------------------------

    \120\ See Letter from Thomas Peterffy, Chairman, Interactive 
Brokers Group (Aug. 1, 2014), at 3 (``Interactive Brokers Letter''), 
available at <a href="https://www.interactivebrokers.com/download/execution_stats_comment_letter.pdf">https://www.interactivebrokers.com/download/execution_stats_comment_letter.pdf</a> (``Payment for order flow has 
often been justified by its advocates based on the claim that the 
receipt of such payments allows brokers to keep commissions low and 
does not affect execution quality (or if it does, such costs are 
passed back to customers in the form of lower commissions). . . . 
[T]he current Rule 605 and 606 statistics published by market 
centers and brokers . . . do not provide a basis for regulators to 
judge these claims, or for customers to judge their broker's 
performance.'').
    \121\ Interactive Brokers Letter at 3.
---------------------------------------------------------------------------

    Commenters have also suggested various ways to expand or modify the 
definition of covered order, including broadening its scope to capture 
additional order types.\122\ In particular, the petitioner for 
rulemaking recommended including short sales, stop orders, and pre-
market orders in Rule 605 reports.\123\ The petitioner stated that 
these order types are ``critical to a complete assessment of execution 
quality,'' and stated that many retail brokers include these orders 
when measuring the execution quality provided by market centers.\124\ A 
commenter to the 2018 Rule 606 Amendments also recommended including 
orders submitted prior to the market open in Rule 605 reports and 
stated that the marketable or non-marketable characteristics of such 
orders cannot be determined under the current framework.\125\

larger order sizes within scope.\126\ The petitioner stated that 
bucketing orders solely by numbers of shares is skewing 
comparisons.\127\ Another commenter, responding to the Commission's 
Concept Release on Equity Market Structure, recommended the following 
order size buckets: one share to 99 shares; 100 shares up to 9,999 
shares, divided into 100 share increments; 10,000 shares to 24,999 
shares; greater than 25,000 shares.\128\ One commenter that offered 
recommendations to modify Rule 605 suggested including a $500,000 
notional cap on all share size buckets.\129\ Another market participant 
expressed support for that cap or a different one.\130\ The market 
participant suggested that a cap of $200,000, consistent with the 
definition of ``block size'' in 17 CFR 242.600(b)(12)(ii), would make 
sense, but noted that benchmark has not changed with inflation.\131\ 
The market participant also stated that the use of notional buckets in 
the ``categorized by order size'' definition would account for 
fractional share and odd-lot orders.\132\

    Commenters have also raised concerns about the current provisions 
in the Rule for timestamps, especially given the speed of today's 
marketplace.\133\ Others have also suggested modifications to improve 
the accessibility and standardizations of reports, including 
centralizing report creation and requiring summary statistics.\134\ In 
several contexts in which the Commission has received general feedback 
on equity market structure, commenters have suggested that the 
Commission require a simplified execution quality report, particularly 
for retail investors.\135\ One commenter on the Concept Release on 
Equity Market Structure stated that if the Commission's goal was for 
execution quality statistics to make the markets more transparent for 
retail investors, the commenter did not believe that was occurring, and 
the average retail investor might benefit more from a simplified 
version of the report.\136\ One EMSAC committee member stated that some 
retail firms have argued that aggregate statistics are more important 
for the retail investor, and that retail investors are not going to 
look at Rule 605 reports.\137\ This EMSAC committee member further 
stated that an issue with aggregation is what to include in the 
aggregate statistics, and depending on a firm's business model, the 
firm may want to

put in different things.\138\ Separately, the EMSAC, as well as a 
commenter to the 2018 Rule 606 Amendments, recommended that the 
Commission incorporate Rule 605 and 606 data into the Commission's data 
visualization tool.\139\

III. Proposed Modifications to Reporting Entities

A. Larger Broker-Dealers

    Rule 605 of Regulation NMS requires market centers, such as 
national securities exchanges, OTC market makers, and ATSs, to produce 
publicly available, monthly execution quality reports. However, broker-
dealers are not included within the scope of Rule 605's reporting 
requirements unless they are market centers. Although Rule 606 requires 
broker-dealers to identify the venues, including market centers, to 
which they route customer orders for execution, customers of those 
broker-dealers do not have access to comprehensive information about 
execution quality. For example, to the extent that a market center's 
execution quality differs for orders received from one broker-dealer 
versus another broker-dealer, that difference would not be apparent 
from currently available execution quality statistics.
    The Commission is proposing to expand the scope of entities that 
must prepare Rule 605 reports to include larger broker-dealers, which 
have a customer-facing line of business. As proposed, Rule 605 would 
include broker-dealers as reporting entities, in addition to market 
centers, but exclude from that expanded requirement broker-dealers that 
do not introduce or carry at least 100,000 customer \140\ accounts. 
This expansion of the scope of Rule 605 would improve the usefulness of 
execution quality statistics, promote fair competition, and enhance 
transparency by providing investors with information that they could 
use to compare the execution quality provided by customer-facing 
broker-dealers. Further, limiting these reporting obligations to 
broker-dealers that have a larger number of customers would focus the 
associated implementation costs on those broker-dealers for which the 
availability of more specific execution quality statistics would 
provide a greater benefit.
---------------------------------------------------------------------------

    \140\ ``Customer'' means any person that is not a broker or 
dealer. See 17 CFR 242.600(b)(23).
---------------------------------------------------------------------------

    Rule 605 and Rule 606 operate together to allow investors to 
evaluate what happens to their orders after investors submit their 
orders to a broker-dealer for execution.\141\ In the current regulatory 
environment, customers that submit held orders (in many cases, 
individual investors) have a limited ability to assess the execution 
quality that their broker-dealers are providing. A customer of a 
broker-dealer can use a broker-dealer's Rule 606 reports to identify 
certain regularly-used venues to which the broker-dealer routes orders 
for execution. However, with respect to held orders, these Rule 606 
reports are not required to include any detailed execution quality 
information.\142\ Moreover, Rule 605 reports prepared by market centers 
commingle orders from all broker-dealers that send covered order flow 
to the reporting market center. Yet a market center may provide 
different execution quality to customers of different broker-dealers, 
and in some cases this difference may be substantial.\143\ Therefore, a 
customer of that broker-dealer must make an inference about the 
execution quality achieved by that particular broker-dealer at a market 
center based on a Rule 605 report that covers all orders received by 
the market center, even though that inference may not be accurate.\144\
---------------------------------------------------------------------------

    \141\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75414.
    \142\ See supra notes 50-55 and accompanying text.
    \143\ See supra notes 108-110 and accompanying text (discussing 
an EMSAC panelist's observations after trying to infer execution 
quality based on available data that one ``fundamental problem'' 
with making these inferences was that a market maker's execution 
quality may vary according to each broker's order flow). See also 
supra note 87 and accompanying text.
    \144\ See supra notes 107-111, 115-118, and 120-121 and 
accompanying text.
---------------------------------------------------------------------------

    Due to this gap in the reporting requirements, variations in 
execution quality provided by a market center to a particular broker-
dealer submitting the order are not observable by market participants 
and other interested parties using publicly available execution quality 
reports.\145\ When requiring each market center to report on all orders 
that it received for execution, the Commission intended to assign the 
disclosure obligation to the entity that would control whether and when 
the order would be executed.\146\ The Commission required market 
centers to include in their Rule 605 reports those orders that they 
routed to another venue for execution, thereby recognizing that market 
centers' decisions about whether and how to route orders can affect 
execution quality.\147\ Likewise, broker-dealers that route customer 
orders make decisions that affect the execution quality that their 
customers' orders receive.
---------------------------------------------------------------------------

    \145\ The Commission preliminarily believes that many 
institutional customers regularly conduct, directly or through a 
third-party vendor, transaction cost analysis of their orders to 
assess execution quality against various benchmarks, but this 
information is not publicly available. The Commission believes that 
some institutional investors may currently use aggregated statistics 
or summaries of Rule 605 reports prepared by third parties, who make 
these reports available for a fee. See infra section VII.C.1.(c)(2).
    \146\ See supra note 33 and accompanying text (citing Adopting 
Release, 65 FR 75414 (Dec. 1, 2000) at 75421).
    \147\ When adopting Rule 605, the Commission stated that from 
the perspective of the customer who submitted the order, the fact 
that a market center chooses to route the order away ``does not 
reduce the customer's interest in a fast execution that reflects the 
consolidated BBO'' that is ``as close to the time of order 
submission as possible,'' and that, consequently, in evaluating the 
quality of order routing and execution, it is important for 
customers to know how the market center handles ``all orders that it 
receives, not just those it chooses to execute.'' Adopting Release, 
65 FR 75414 (Dec. 1, 2000) at 75423.
---------------------------------------------------------------------------

    In addition, while the Commission adopted Rule 605 in 2000 as a 
``minimum step necessary to address fragmentation,'' \148\ the equities 
markets have grown even more fragmented since that time.\149\ Broker-
dealers have many choices about where to route customer orders for 
execution. But broker-dealers may face conflicts of interest when 
discussing arrangements regarding the outsourcing of customer order 
flow, including those that involve PFOF, and making routing 
decisions.\150\ With respect to orders submitted on a held basis, 
broker-dealers must include information about their payment 
relationships with execution venues in quarterly reports prepared 
pursuant to Rule 606(a)(1).\151\ Without information

[[Page 3796]]

about the execution quality that broker-dealers in the business of 
routing customer orders obtain for those orders, market participants 
and other interested parties lack key information that would facilitate 
their ability to evaluate how these payment relationships may affect 
execution quality. Recognizing these and other concerns, the EMSAC and 
other commenters in multiple contexts have suggested that the 
Commission expand the scope of Rule 605 to require reporting by broker-
dealers.\152\
---------------------------------------------------------------------------

    \148\ See supra note 9 and accompanying text.
    \149\ See supra notes 74-84 and accompanying text.
    \150\ See supra notes 88-89 and accompanying text.
    \151\ See supra notes 50-52 and accompanying text. As discussed 
above (supra section II.D), Rule 606 requires broker-dealers to 
identify and report data according to execution venue, rather than 
by market center. Not all execution venues reflected on Rule 606 
reports will necessarily fall within Regulation NMS's definition of 
``market center.'' See, e.g., 2018 Rule 606 Amendments Release, 83 
FR 58338 (Nov. 19, 2018) at 58365 (stating that the Commission's 
reference to ``venues'' for purposes of Rule 606(b)(3) is meant to 
refer to external liquidity providers to which the broker-dealer may 
send actionable indications of interest (``IOIs''), and that this 
category of market participants likely would include market centers 
as defined in Rule 600(b)(38), but may not be limited to such market 
centers).
    \152\ See generally supra section II.E.
---------------------------------------------------------------------------

    Consequently, the Commission is now proposing to require larger 
broker-dealers to prepare and publish execution quality reports 
pursuant to Rule 605, through the proposed revisions to Rule 605 and 
the addition of proposed Rule 605(a)(7). This expansion of the scope of 
reporting entities would increase transparency into the differences in 
execution quality achieved by broker-dealers when they route customer 
orders to execution venues, and thereby would make the execution 
quality statistics more useful to market participants and other 
interested parties.\153\ This change would increase competition among 
broker-dealers that accept customer orders for execution by providing 
information that market participants can use to evaluate and compare 
broker-dealers' execution quality. This could lead to faster 
executions, better price improvement, and a shift in order flow to 
those broker-dealers offering the best execution quality for their 
customers. This would further the national market system objectives set 
forth in section 11A(a)(1) of the Exchange Act, including the efficient 
execution of securities transactions, fair competition among market 
participants, the public availability of information on securities 
transactions, and the best execution of investor orders.\154\
---------------------------------------------------------------------------

    \153\ Among the commenters that raised concerns about the lack 
of available information regarding the execution broker-dealers 
provide to their customers' orders, one commenter stated that there 
is a ``fundamental flaw'' in the logic of Rule 605 and Rule 606 
because these rules assume that execution quality is solely the 
function of the market center, but instead execution quality is a 
product of a combination of the broker's skill and the quality of 
the market center's execution. See supra notes 117-118 and 
accompanying text. The proposal would address this concern by 
requiring larger broker-dealers to produce execution quality 
reports, rather than leaving market participants and other 
interested parties to rely solely on the execution quality reports 
produced by the market centers to which a particular broker-dealer 
routes orders.
    \154\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75414 
n.1, 75417 (citing 15 U.S.C. 78k-1).
---------------------------------------------------------------------------

    Specifically, the Commission is proposing to amend Rule 605 to 
apply the reporting requirements contained therein to brokers and 
dealers, in addition to market centers. Where current Rule 605 refers 
to ``market centers,'' the Commission is proposing to insert references 
to ``brokers'' and ``dealers.'' \155\ The proposed expansion of Rule 
605's reporting requirements to cover broker-dealers would also affect 
Rule 600 of Regulation NMS. Specifically, the definition of ``covered 
order'' in Rule 600(b)(22) refers to ``any market order or any limit 
order (including immediate-or-cancel orders) received by a market 
center.'' \156\ The Commission is proposing to amend this provision to 
refer to orders ``received by a market center, broker, or dealer.'' 
\157\ Further, as noted above, the Plan establishes procedures for 
market centers to follow in making available to the public the monthly 
reports required by the Rule.\158\ Because of the proposed amendments 
to the Rule, the existing Plan would no longer comply with proposed 
Rule 605(a)(3) and thus would need to be updated in order to 
incorporate references to broker-dealers subject to the Rule.\159\ As 
is currently the case for market centers that are not Participants, the 
Participants would be required to enforce compliance with the terms of 
the Plan by their members and person associated with their 
members.\160\
---------------------------------------------------------------------------

    \155\ See proposed Rules 605 (introductory paragraph), 605(a) 
(caption), 605(a)(1), 605(a)(1)(i)(D), 605(a)(3), 605(a)(4), 
605(a)(5), and 605(a)(6).
    \156\ 17 CFR 242.600(b)(22). The Commission is proposing to 
renumber the definition of ``covered order'' as proposed Rule 
600(b)(30).
    \157\ See proposed Rule 600(b)(30).
    \158\ See supra section II.B.3.
    \159\ The Plan details procedures for market centers to follow 
and, among other things, specifies the order and format of fields in 
a manner that aligns with current Rule 605(a)(1). See Plan generally 
and section VI(a) of the Plan. Under current Rule 605(a)(2), every 
national securities exchange trading NMS stocks and each national 
securities association is required to act jointly in establishing 
procedures for market centers to follow in making the reports 
required by Rule 605(a)(1) available to the public in a uniform, 
readily accessible, and usable electronic form. See 17 CFR 
242.605(a)(2). The proposal would add brokers and dealers to the 
scope of entities to be covered by the Plan's procedures and 
renumber Rule 605(a)(2) as Rule 605(a)(3). See proposed Rule 
605(a)(3). The Plan would also need to be updated to accommodate any 
new data elements in the order and format of fields.
    \160\ See 17 CFR 242.608(c). See also supra note 47 (describing 
Participants and Designated Participants under the Plan).
---------------------------------------------------------------------------

    The Commission is mindful that Rule 605's execution quality reports 
contain a large volume of statistical data, and as a result it may be 
difficult for individual investors to review and digest the reports. 
The Commission considered the volume of execution quality statistics 
that would be produced when adopting Rule 605, and stated that the 
large volume of statistics reflects a deliberate decision by the 
Commission to avoid the dangers of overly general statistics that could 
hide significant differences in execution quality.\161\ By requiring 
brokers-dealers to report stock-by-stock order execution information in 
a uniform manner, the proposal would make it possible for market 
participants and other interested parties to make their own 
determinations about how to group stocks or orders when comparing 
execution quality across broker-dealers.\162\ Further, to the extent 
that certain market participants may not have the means to directly 
analyze the detailed statistics,\163\ the Commission expects that 
independent analysts, consultants, broker-dealers, the financial press, 
and market centers will respond to the needs of investors by analyzing 
the disclosures and producing more digestible information using the 
data, as the Commission anticipated when approving the predecessor to 
Rule 605 and has observed since that time.\164\ As discussed further 
below, the Commission also is proposing to require all market centers 
and broker-dealers that would be subject to Rule 605's reporting 
requirements to produce summary reports with aggregated execution 
quality information.\165\ Requiring broker-dealers to produce more 
detailed execution quality data would help ameliorate potential 
concerns about overly general statistics, or about the specific 
categorization of orders and selection of metrics in the summary 
reports, by allowing market participants and other interested parties 
to conduct their own analysis based on

[[Page 3797]]

alternative categorizations of the underlying data.
---------------------------------------------------------------------------

    \161\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75419. 
See also id. (stating that after this basic information is disclosed 
by all market centers in a uniform manner, market participants and 
other interested parties will be able to determine the most 
appropriate classes of stocks and orders to use in comparing 
execution quality across market centers).

supra note 112 and accompanying text (EMSAC committee member stating 
that retail investors will not look at the Rule 605 reports); note 
118 (commenter stating that Rule 605 data is too raw for most 
investors to interpret); note 119 and accompanying text (commenter 
stating that most retail investors may not use the disclosures 
directly).

    \165\ See infra section V.
---------------------------------------------------------------------------

    Proposed Rule 605(a)(7) states that a broker or dealer that is not 
a market center shall not be subject to the requirements of Rule 605 
unless that broker or dealer introduces or carries 100,000 or more 
customer accounts through which transactions are effected for the 
purchase or sale of NMS stocks (the ``customer account 
threshold'').\166\ The Commission is mindful of the additional costs 
that broad expansion of the rule to broker-dealers would entail. The 
relative benefit of having a broker-dealer prepare Rule 605 reports 
increases when the broker-dealer has more customers. The Commission is 
proposing a minimum reporting threshold of 100,000 customers to balance 
the benefits of having broker-dealers produce execution quality 
statistics with the costs of implementation and continued 
reporting.\167\
---------------------------------------------------------------------------

    \166\ In addition, as discussed further below, proposed Rule 
605(a)(7) states that any broker or dealer that meets or exceeds 
this customer account threshold and is also a market center shall 
produce separate reports pertaining to each function.
    \167\ See infra section VII.D.2 for a discussion of the costs of 
the proposed amendments to Rule 605. As discussed further below, 
broker-dealers that were previously not required to publish Rule 605 
reports would incur initial costs to develop the policies and 
procedures to post Rule 605 reports for the first time, and all 
broker-dealers would face ongoing costs to continue to prepare them 
each month. Other potential costs include a potential for less 
transparency or lower execution quality, and the costs to update 
best execution methodology. See also infra section VII.E.1.(a) for a 
discussion about the potential costs of imposing Rule 605's 
reporting requirements on broker-dealers with a smaller number of 
customer accounts.
---------------------------------------------------------------------------

    Analysis indicates that approximately 85 broker-dealers (or 
approximately 6.7% of customer-carrying broker-dealers) introduce or 
carry more than 100,000 customer accounts and these broker-dealers 
together handle over 98% of customer accounts.\168\ Utilizing a 100,000 
customer account threshold would allow the Rule 605 reporting 
requirements to capture those broker-dealers that introduce or carry 
the vast majority of customer accounts, while subjecting only a 
relatively small percentage of broker-dealers that accept customer 
orders for execution to the reporting obligation and excluding those 
broker-dealers that introduce or carry a smaller number of customer 
accounts. Although utilizing a lower customer account threshold, such 
as 10,000 customer accounts, would result in capturing substantially 
more transactions, the lower customer account threshold would result in 
capturing only marginally more customer accounts. This implies that the 
additional customer coverage would result from a small number of 
accounts that trade in large volumes. Therefore, the additional 
coverage may not be as beneficial because many of the additional 
customer accounts that would be included with a lower threshold likely 
belong to institutional traders that have access to alternative 
execution quality information and also are likely to use not held 
orders, which are not included in Rule 605 reports.\169\
---------------------------------------------------------------------------

    \168\ See infra Table 13 for cost-benefit analysis of different 
customer account thresholds defining ``larger broker-dealer'' and 
infra note 1008 and accompanying text for methodology. For example, 
approximately 45 broker-dealers introduce or carry more than 500,000 
customer accounts and these broker-dealers together handle over 96% 
of customer accounts. Further, approximately 235 broker-dealers 
introduce or carry more than 10,000 customer accounts and these 
broker-dealers together handle over 99% of customer accounts. See 
infra Table 13.
    \169\ See infra note 1011 and accompanying text; Table 13. See 
also infra section VII.E.1.(a) for further discussion of alternative 
customer account thresholds.
---------------------------------------------------------------------------

    The Commission considered using the volume of broker-dealers' 
customer transactions, rather than the number of their customer 
accounts, for purposes of establishing a reporting threshold. Although 
establishing a reporting threshold using the number of customer 
transactions would likely capture a larger number of customer orders 
than the proposed customer account threshold, this approach would 
likely exclude broker-dealers that have a larger number of relatively 
inactive customer accounts and include broker-dealers that have a small 
number of customer accounts associated with large amounts of trading 
volume. In each respect, the reporting threshold would be less likely 
to capture individual investor orders and more likely to capture 
institutional investor orders, and therefore the threshold would be 
less likely to target the types of orders that may be most useful for 
consumers of Rule 605 reports. In addition, utilizing a threshold based 
on the number of customer transactions may result in a less stable set 
of broker-dealers that are subject to Rule 605's reporting 
requirements, because transaction volume is more likely than customer 
account numbers to vary significantly from month to month based on 
market conditions. Further, the number of their customer accounts is 
likely less costly for broker-dealers to calculate and track as 
compared to the volume of transactions associated with their customer 
accounts.\170\
---------------------------------------------------------------------------

    \170\ See infra section VII.E.1.(c) for further discussion about 
using a threshold based on the number of customer transactions.
---------------------------------------------------------------------------

    The Commission also considered EMSAC's recommendation to expand the 
scope of Rule 605 to cover all broker-dealers, which contemplated 
excluding only broker-dealers with de minimis order flow.\171\ The 
Commission is preliminarily concerned that subjecting a significantly 
larger number of broker-dealers to Rule 605's reporting requirements 
would substantially increase the costs of the proposal and that the 
increase in cost that would accompany the use of a de minimis threshold 
would not be justified by the corresponding benefit.\172\ This concern 
about requiring smaller broker-dealers to prepare Rule 605 reports is 
present with any de minimis threshold, whether based on order flow as 
the EMSAC suggested or on some other measure such as number of customer 
accounts.

    \172\ See infra note 1011 and accompanying text and Table 13 
(showing that, for example, adjusting the customer account threshold 
from 100,000 customer accounts to 10,000 customer accounts would 
increase the estimated costs from approximately $5 million to 
approximately $13.9 million).
---------------------------------------------------------------------------

    The proposed customer account threshold would require brokers-
dealers to include in their calculations the public customer accounts 
that they introduce, as well as the customer accounts that they 
carry.\173\ Rule 605 reports that reflect orders received from customer 
accounts that a broker-dealer introduces or carries would provide 
useful information to market participants because both introducing and 
carrying broker-dealers make decisions about where to route those 
orders and it would be helpful for customers to be able to evaluate the 
execution quality received as a result of those decisions.\174\ An 
introducing broker-dealer may choose to utilize an omnibus clearing 
arrangement and not disclose certain information about its underlying 
customer accounts to the clearing firm.\175\ In such circumstances,

[[Page 3798]]

because the clearing broker may not have access to information about 
how many customer accounts a particular omnibus account represents, the 
proposal specifies that when an omnibus clearing arrangement is used 
the underlying customer accounts would be required to be counted as 
accounts carried by the introducing broker-dealer rather than by the 
clearing broker. Therefore, for purposes of Rule 605, a broker or 
dealer that utilizes an omnibus clearing arrangement for any of its 
underlying customer accounts would be considered to carry such 
underlying customer accounts when calculating the number of customer 
accounts that it introduces or carries.\176\
---------------------------------------------------------------------------

    \173\ See proposed Rule 605(a)(7).
    \174\ An introducing broker-dealer is a broker-dealer that has a 
contractual arrangement with another firm, known as the carrying or 
clearing firm, under which the clearing/carrying firm agrees to 
perform certain services for the introducing firm. Usually, the 
introducing firm transmits its customer accounts and customer orders 
to the clearing/carrying firm, which executes the orders and carries 
the account. See Securities Exchange Act Release No. 31511 (Nov. 24, 
1992), 57 FR 56973, 56978 (Dec. 2, 1992) (Net Capital Rule).
    \175\ Some broker-dealers utilize an ``omnibus clearing 
arrangement,'' where the clearing firm maintains one account for all 
of customer transactions of the introducing firm, rather than a 
``fully disclosed introducing relationship.'' In an omnibus 
arrangement, the clearing firm does not know the identity of the 
customers of the introducing firm, whereas in a fully-disclosed 
arrangement, the clearing/carrying firm knows the names, addresses, 
securities positions, and other relevant data as to each customer. 
See id. at 56978 n.16.
    \176\ See proposed Rule 605(a)(7). For example, an introducing 
broker-dealer that utilizes an omnibus clearing arrangement for 
100,000 customer accounts and separately carries 50,000 customer 
accounts would be considered, for purposes of proposed Rule 605, to 
carry 150,000 customer accounts. In contrast, a broker-dealer who 
introduces, on a fully-disclosed basis, 125,000 customer accounts 
would be considered, for purposes of proposed Rule 605, to introduce 
125,000 customer accounts. In both cases, the introducing broker-
dealers would exceed the proposed customer account threshold.
---------------------------------------------------------------------------

    Requiring both introducing broker-dealers and carrying broker-
dealers to prepare Rule 605 reports might result, in some instances, in 
the same underlying order being reflected on multiple broker-dealers' 
Rule 605 reports. However, Rule 605 does not require reports that 
reflect execution quality on an order-by-order basis and the separate 
reports would provide different views of execution quality specific to 
the group of orders handled by each broker-dealer. Moreover, the 
current structure of Rule 605 already contemplates that certain orders 
may be reflected on more than one report, in the case of orders that 
are received by one market center and then routed to another market 
center for execution.\177\
---------------------------------------------------------------------------

    \177\ See 17 CFR 242.605(a)(1).
---------------------------------------------------------------------------

    Proposed Rule 605(a)(7) states that any broker or dealer that meets 
or exceeds the customer account threshold and is also a market center 
shall produce separate reports pertaining to each function. Therefore, 
a broker-dealer that meets or exceeds the customer account threshold 
and is also a market center would be required to produce one report 
that includes all of the covered orders in NMS stocks that it received 
for execution when acting as a market center and a separate report that 
includes all of the covered orders in NMS stocks that it received for 
execution when acting as a broker-dealer. Requiring a firm to produce 
separate reports pertaining to its market center function and its 
broker-dealer function would allow market participants and other 
interested parties to view the firm's execution quality from the 
perspective of how it operates in each of these separate roles.
    This aspect of the proposal would not change how a firm should 
determine when it is acting as a market center, as that term is defined 
in Rule 600(b)(46).\178\ In particular, some firms that are larger 
broker-dealers also act as OTC market makers, which are a type of 
market center. Currently, to the extent that a dealer holds itself out 
as being willing to buy from and sell to its customers, or others, in 
the United States, an NMS stock for its own account on a regular or 
continuous basis otherwise than on a national securities exchange in 
amounts of less than a block size, that dealer is defined as an OTC 
market maker.\179\ For example, if a broker-dealer executes certain 
types of orders internally (e.g., fractional share orders, small-sized 
orders, or orders in particular symbols), that broker-dealer may be 
acting as an OTC market maker, and thus a market center, for those 
specific types of orders. Moreover, Rule 605 requires that any report 
pertaining to a market center include all covered orders that it 
received for execution from any person, whether executed at the market 
center or at any other venue.\180\ As is the case under Rule 605 
currently for market centers that route orders away, under the 
proposal, the fact that a larger broker-dealer has routed certain 
covered orders away for execution would not alone be the basis on which 
to determine that it did not act as a market center with respect to 
those orders.\181\
---------------------------------------------------------------------------

    \178\ See 17 CFR 242.600(b)(46). The Commission is proposing to 
renumber the definition of ``market center'' as proposed Rule 
600(b)(56).
    \179\ See supra note 28. See also Securities Exchange Act 
Release No. 37619A (Sept. 6, 1996), 61 FR 48290, 48318-19 (Sept. 12, 
1996) (Order Execution Obligations) (stating that dealers that 
internalize customer order flow in particular stocks by holding 
themselves out to customers as willing to buy and sell on an ongoing 
basis would fall within the definition of ``OTC market maker'' as 
defined in the predecessor to Rule 602 of Regulation NMS, even 
though they may not hold themselves out to all other market 
participants, and that dealers that hold themselves out to 
particular firms as willing to receive customer order flow, and 
execute those orders on a regular or continuous basis, also would 
fall within the definition of an OTC market maker); id. at 48319 
(stating that broker-dealers will not be considered to be holding 
themselves out as regularly or continuously willing to buy or sell a 
security if they occasionally execute a trade as principal to 
accommodate a customer's request, and that, in response to the 
suggestion of some commenters, the Commission has modified the 
proposed amendment to the definition of ``OTC market maker'' to make 
clear that more than an isolated transaction is necessary before a 
dealer is designated an OTC market maker).
    \180\ See 17 CFR 242.605(a)(1). We note that the staff has 
provided their views on a way that a firm might determine the scope 
of covered orders for which it acts as a market center, see Division 
of Market Regulation: Staff Legal Bulletin No. 12R (Revised), 
Question 4 (June 22, 2001), available at <a href="https://www.sec.gov/interps/legal/slbim12a.htm">https://www.sec.gov/interps/legal/slbim12a.htm</a> (``The Rule applies to broker-dealers 
insofar as they act as a `market center' with respect to orders 
received from other persons. Consequently, for orders in securities 
for which Firm X does not act as an OTC market maker, Firm X would 
not be acting as a market center in those securities and therefore 
need not report on orders in those securities that it receives as an 
agent and routes elsewhere for execution. Conversely, the orders 
that Firm X receives from any person in the 500 securities in which 
it acts as an OTC market maker (and therefore is a market center) 
generally must be included in Firm X's monthly reports, even if Firm 
X ultimately routes some of the orders to other market centers for 
execution.''). Staff reports, Investor Bulletins, and other staff 
documents (including those cited herein) represent the views of 
Commission staff and are not a rule, regulation, or statement of the 
Commission. The Commission has neither approved nor disapproved the 
content of these staff documents and, like all staff statements,

law, and create no new or additional obligations for any person.
    \181\ See supra notes 143-144 and accompanying text.
---------------------------------------------------------------------------

    For a larger broker-dealer that is also a market center, the report 
pertaining to its broker-dealer function would cover all orders that 
the broker-dealer received for execution as part of its customer-facing 
line of business, whether executed internally or routed away. An order 
would need to be reflected on both the report regarding the firm's 
market center function and the report regarding its broker-dealer 
function, if the broker-dealer received the order from a customer and 
also acts as a market center for that type of order. Each report would 
provide a different view of the firm's execution quality based on a 
different aspect of its business, and because reports reflect orders 
grouped by symbol, order type, and size, would reflect different 
execution quality metrics to the extent that the group of orders 
covered by the different reports did not overlap completely.\182\
---------------------------------------------------------------------------

    \182\ For certain firms regarding certain symbols, order types, 
or order sizes, the group of orders for which the firm acts as a 
larger broker-dealer may overlap completely with the group of orders 
for which the firm acts as a market center. However, broker-dealer 
firms are structured in myriad different ways, and the degree of 
overlap among reports might not remain stable over time; therefore, 
requiring firms to produce reports according to the orders for which 
they act as a market center and the orders for which they act as a 
broker-dealer would help keep the reports consistent with firms' 
lines of business.
---------------------------------------------------------------------------

    As proposed, pursuant to Rule 605(a)(7), a broker-dealer would be 
excluded from Rule 605's reporting requirements only with respect to 
its customer-facing broker-dealer function (as opposed to its function 
as market center, if applicable) as long as the

[[Page 3799]]

number of customer accounts that it introduces or carries continues to 
be less than the customer account threshold. A broker-dealer would no 
longer be excluded from Rule 605 once and as long as it meets or 
exceeds the customer account threshold; however, a broker-dealer that 
meets or exceeds the customer account threshold for the first time 
would have a grace period before being required to comply with Rule 
605's reporting requirements, as described further below.
    Proposed Rule 605(a)(7) states that a broker or dealer that meets 
or exceeds the customer account threshold shall be required to produce 
reports pursuant to this section for at least three calendar months 
(``Reporting Period''). The Reporting Period would begin the first 
calendar day of the next calendar month after the broker or dealer met 
or exceeded the customer account threshold, unless it is the first time 
the broker-dealer has met or exceeded the customer account 
threshold.\183\ Any time after a broker or dealer has been required to 
produce reports pursuant to this proposed section for at least a 
Reporting Period, if a broker or dealer falls below the customer 
account threshold, the broker or dealer would not be required to 
produce a report pursuant to this paragraph for the next calendar 
month.\184\ The Reporting Period would start on the first day of the 
next calendar month after the customer account threshold has been 
crossed because this timing would align with Rule 605's monthly 
reporting period and avoid requiring broker-dealers to produce a report 
that covers a partial month, which would be less comparable with the 
monthly reports of other broker-dealers. Moreover, brokers-dealers that 
may at times fall below the customer account threshold would be 
required to produce reports pursuant to Rule 605 for at least three 
calendar months, because this minimum reporting period would help 
ensure a period of continuity in reporting. If instead a broker-dealer 
could fluctuate in and out of being required to comply with the 
reporting requirements from month-to-month, it would potentially be 
disruptive to the broker-dealer to have to coordinate compliance with 
the Rule on some months but not others and could interfere with 
customers' or market participants' ability to look at a broker-dealer's 
execution quality over time by analyzing historical data.\185\
---------------------------------------------------------------------------

    \183\ See proposed Rule 605(a)(7).
    \184\ See id.
    \185\ When discussing the 2018 amendments to Rule 605(a)(2) that 
required market centers to keep Rule 605(a) reports posted on a 
public website for a period of three years, the Commission stated 
that it expected customers and the public to use the historical 
information to compare information from the same time period. See 
2018 Rule 606 Amendments Release, 83 FR 58338 (Nov. 19, 2018) at 
58380 (also stating that, with respect to market centers voluntarily 
posting Rule 605(a) reports that were created prior to the amended 
rule's effectiveness, making historical data available to customers 
and the public could be useful to customers or market participants 
seeking to analyze such data).
---------------------------------------------------------------------------

    The Commission is proposing that, the first time a broker or dealer 
has met or exceeded the customer account threshold, there would be a 
grace period of three calendar months before the Reporting Period 
begins and the broker or dealer must comply with the reporting 
requirements of Rule 605.\186\ A limited three-month grace period is 
appropriate because it would provide a broker-dealer that crosses the 
customer account threshold for the first time with a period of time in 
which to come into compliance with Rule 605's reporting requirements. 
The three-month grace period would afford a broker-dealer adequate time 
to develop the systems and processes and organize the resources 
necessary to generate the reports pursuant to Rule 605, while still 
requiring the broker-dealer to begin reporting without an overly long 
delay. At the same time, should a broker-dealer subsequently fall below 
the customer reporting threshold, the Commission preliminarily believes 
that the broker-dealer should already have the necessary systems and 
processes in place and therefore a grace period would not be necessary 
if that broker-dealer again meets or exceeds the customer account 
threshold and becomes subject to Rule 605's requirements. The 
Commission notes that Rule 606 similarly provides for a three-month 
grace period for brokers or dealers subject to Rule 606(b)(3)'s 
reporting requirements for the first time only.\187\
---------------------------------------------------------------------------

    \186\ See proposed Rule 605(a)(7). After the three calendar 
month grace period, the Reporting Period would begin on the first 
calendar day of the fourth calendar month after the broker or dealer 
has met or exceeded the customer account threshold. See id. As 
described above, a broker-dealer that meets or exceeds the customer 
account threshold would be required to produce Rule 605 reports for 
at least a Reporting Period. See supra notes 183-184 and 
accompanying text. Therefore, a broker-dealer that crosses the 
customer account threshold for the first time would be required to 
comply with the reporting requirements of Rule 605 for at least a 
Reporting Period, even if that broker-dealer falls below the 
customer account threshold during the grace period.
    \187\ See 17 CFR 242.606(b)(4).
---------------------------------------------------------------------------

    Rule 605 requires that reporting entities calculate certain 
statistics based on the time of order receipt.\188\ Moreover, 
Regulation NMS defines ``time of order receipt'' based on the time an 
order was received by a market center for execution.\189\ In 
conjunction with the proposed expansion of Rule 605 to cover larger 
broker-dealers, it is necessary to modify this definition to specify 
how broker-dealers that are not acting as market centers would be 
required to calculate ``time of order receipt.'' The Commission has 
considered requiring broker-dealers to calculate the ``time of order 
receipt'' based on the time that the broker-dealer received the order 
or on the time that the broker-dealer transmitted the order to a market 
center for execution. Measuring ``time of order receipt'' based on when 
a broker-dealer received the order would provide a view of how that 
broker-dealer handled that order from the time the order was within its 
control, rather than limiting that view to what happened after the 
broker-dealer sent the order to a particular market center for 
execution. In this way, calculating execution quality statistics based 
on the time that a broker-dealer received the order could provide 
information about whether a broker-dealer's delay in sending the order 
to a market center for execution may have affected the execution 
quality obtained for that order, because the execution quality 
statistics would be measured based on the prevailing market prices at 
that time.\190\ Accordingly, the Commission is proposing to modify the 
definition of ``time of order receipt'' to specify that, in the case of 
a broker or dealer that is not acting as a market

[[Page 3800]]

center, the time of order receipt is the time that the order was 
received by the broker or dealer for execution.\191\
---------------------------------------------------------------------------

    \188\ See, e.g., 17 CFR 242.605(a)(1)(ii)(D) (measuring, for 
shares executed with price improvement, the share-weighted average 
period from the time of order receipt to the time of order 
execution).
    \189\ See 17 CFR 242.600(b)(92). See also Adopting Release, 65 
FR 75414 (Dec. 1, 2000) at 75423 (``The definition [of `time of 
order receipt'] is intended to identify the time that an order 
reaches the control of the market center that is expected, at least 
initially, to execute the order.''). The Commission is proposing to 
renumber the definition of ``time of order receipt'' as proposed 
Rule 600(b)(109).
    \190\ When adopting Rule 605, the Commission stated that a 
market center will use the time and consolidated BBO at the time it 
received the order, rather than the time and consolidated BBO when 
the venue to which an order was forwarded received the order, to 
calculate the required statistics. See Adopting Release, 65 FR 75414 
(Dec. 1, 2000) at 75423. The Commission stated that a market center 
should be held accountable for all orders that it receives for 
execution and should not be given an opportunity to exclude 
difficult orders by routing them to other venues, and that from the 
customer's perspective the fact that a market center chooses to 
route the order elsewhere does not reduce the customer's interest in 
a fast execution that reflects the consolidated BBO as close to the 
time of order submission as possible. See id. This same reasoning 
applies to orders that a broker-dealer receives and then routes to 
another venue for execution, and supports measuring the time of 
order receipt from the time that the broker-dealer receives the 
order.
    \191\ See proposed Rule 600(b)(109). The time that the order is 
received by the market center for execution should be the same as 
the time that the order is received by the broker-dealer for 
execution when the broker-dealer also acts as a market center for 
that order.
---------------------------------------------------------------------------

    The Commission is mindful that some of Rule 605's execution quality 
statistics may as a general matter differ for the larger broker-
dealers, as compared to market centers, to the extent that some of 
these larger broker-dealers generally or exclusively route orders away. 
However, it is appropriate for broker-dealers to report on the same 
execution quality statistics as market centers because the reported 
statistics can be understood in the context of the specific reporting 
entity, and the detailed execution quality statistics would allow 
customers and other market participants to parse the differences among 
the statistics for each reporting entity. For example, Rule 605 
requires statistics for the number of shares executed at the receiving 
market center and the number of shares executed at any other 
venue.\192\ As discussed above, broker-dealers that generally route the 
orders that they receive to other venues for execution, and thereby 
would report these shares as being executed at another venue, may 
execute certain portions of their order flow internally (e.g., 
fractional shares).\193\ While the Commission considered whether or not 
broker-dealers should be required to provide execution quality 
statistics for both shares executed at the receiving broker-dealer and 
shares executed at any other venue, the Commission decided to propose 
to keep both of these statistics in the Rule 605 reporting requirements 
for broker-dealers so as to capture all orders that broker-dealers 
receive for execution as part of their customer-facing broker-dealer 
function.\194\ Further, differences in certain statistics for broker-
dealers as compared to market centers may be more reflective of 
differences in business models rather than effectiveness in achieving 
execution quality for covered orders because of differences in order 
handling practices. The Commission understands that these differences 
are well-known and are taken into account by market participants when 
evaluating execution quality statistics. For example, broker-dealers 
that route customer orders may have consistently longer time to 
executions as compared to market centers for similar orders, because of 
the time it takes to route these orders, but this difference is well 
understood by market participants.
---------------------------------------------------------------------------

    \192\ See 17 CFR 242.605(a)(1)(i)(D) and (E). As discussed 
herein, the Commission is proposing to modify Rule 605(a)(1)(i)(D) 
to also cover the number of shares executed at the receiving broker 
or dealer. See supra note 155 and accompanying text.
    \193\ See supra note 34 and accompanying text.
    \194\ If a broker-dealer does not execute any covered orders 
internally, then that broker-dealer's Rule 605 report would not 
reflect any shares executed at the receiving broker-dealer. For 
discussion of what orders broker-dealers that are market centers 
would include in their reports pertaining to their market center 
function, see supra notes 178-180 and accompanying text.
---------------------------------------------------------------------------

    The Commission is also mindful that, for orders routed to other 
venues for execution, broker-dealers may not have all of the 
information needed to calculate the proposed statistics at the time of 
order execution. However, these broker-dealers should be able to obtain 
the needed information in time to prepare the required reports. Broker-
dealers would need to calculate their execution quality statistics, or 
engage a vendor to calculate the statistics on their behalf, on a 
monthly basis. At the time that the broker-dealer or its vendor would 
need to calculate the execution quality statistics, the broker-dealer 
would have received any needed information about the order's execution 
from the execution venue and be able to obtain any needed historical 
price information from publicly available data sources, such as the 
exclusive plan processors (``exclusive SIPs'').\195\ For example, a 
broker-dealer that routed an order away for execution would receive 
time of order execution and execution price as part of the trade 
confirmation provided by the execution venue. The broker-dealer could 
then use historical price information available via the exclusive SIPs 
to determine the NBBO at the time of order receipt and at the time of 
order execution, the number of shares displayed at the NBBO, and the 
best available displayed price, if such price is being disseminated, 
and use this data to calculate the required execution quality 
statistics.\196\
---------------------------------------------------------------------------

    \195\ See MDI Adopting Release, 86 FR 18596 (Apr. 9, 2021) at 
18598-99 (describing that the exclusive SIPS, among other things, 
disseminate core data, which currently consists of: (1) the price, 
size, and exchange of the last sale; (2) each exchange's current 
highest bid and lowest offer and the shares available at those 
prices; and (3) the NBBO). A securities information processor 
(``SIP'') is defined in section 3(a)(22)(A) of the Exchange Act. See 
15 U.S.C. 78c(a)(22)(A). Further, an ``exclusive processor'' (also 
known as an exclusive SIP) is defined in section 3(a)(22)(B) of the 
Exchange Act. See 15 U.S.C. 78c(a)(22)(B).
    \196\ With respect to NMLOs, the broker-dealer could also use 
this historical price information available via the exclusive SIPs 
to determine when the order became executable, based on when the 
NBBO first reached the order's limit price.
---------------------------------------------------------------------------

Request for Comment
    The Commission seeks comment generally on the proposed expansion of 
Rule 605 reporting requirements to include larger broker-dealers that 
meet or exceed the customer account threshold, as well as the other 
proposed changes to Rule 605 and Rule 600(b) discussed above. In 
particular, the Commission solicits comment on the following:
    1. Should Rule 605 be expanded to apply to broker-dealers? Why or 
why not? Do commenters agree that it would be useful for customers of 
certain broker-dealers to be able to access execution quality 
statistics that are specific to those broker-dealers, rather than 
needing to rely on the execution quality statistics reported by the 
market centers to which the broker-dealers route? Do commenters agree 
that market centers may provide different execution quality to orders 
based on the routing broker-dealer? Please explain and provide data.
    2. Do commenters agree that it would be useful for broker-dealers 
that are also market centers to produce separate reports pertaining to 
each function? Why or why not? Do commenters agree that broker-dealers 
that are also market centers should be required to include in the 
report pertaining to their market center function all covered orders 
for which they act as a market center, including as an OTC market 
maker, rather than only those covered orders executed at the market 
center? Do commenters agree that broker-dealers that are also market 
centers should be required to include in the report pertaining to their 
broker-dealer function all of the covered orders in NMS stocks that 
they received for execution from any customer, rather than only those 
orders that do not pertain to their market center function (i.e., those 
orders for which they do not act as a market center)? Would broker-
dealers that are also market centers encounter any specific 
difficulties when determining which orders to include in each report? 
Please explain.
    3. Is a numerical customer account threshold the proper criterion 
for determining whether a broker-dealer should be subject to the Rule 
605 reporting requirements? If so, is 100,000 or more customer accounts 
the appropriate amount? Why or why not? If not, should be it higher or 
lower (e.g., 500,000 or more customer accounts or 10,000 or more 
customer accounts)? If so, by what amount? Is it appropriate to 
consider both the number of customer accounts that the broker-dealer 
carries and the number of customer accounts

[[Page 3801]]

that the broker-dealer introduces? Why or why not? Do commenters 
believe that it would be more useful to consider the trading volume, 
either based on share volume or notional volume, or both, of a broker-
dealer's customers when setting the reporting threshold? Why are why 
not? Please explain and provide data to support your argument. Are 
there alternative approaches that the Commission should adopt in 
expanding Rule 605's reporting requirements to broker-dealers? If so, 
please explain the approach in detail, including the benefits and costs 
of the approach.
    4. Should the Commission require all broker-dealers to report 
pursuant to Rule 605 irrespective of the number of customer accounts 
that the broker-dealer carries or introduces? Or should such a 
requirement be subject to a de minimis exclusion? Why or why not? If 
so, what would be an appropriate de minimis exclusion? Please explain 
and provide data, if possible.
    5. Is three months an appropriate timeframe to use for the 
Reporting Period, i.e., the minimum length of time for which a broker-
dealer would need to comply with Rule 605's reporting requirements once 
its number of customer accounts meets or exceeds the customer account 
threshold? Would a shorter or longer time period (e.g., one, two or six 
months) be more appropriate? If so, by what amount? Does whether or not 
a broker-dealer uses or could use an outside vendor to prepare reports 
pursuant to Rule 605 affect this answer? Please explain.
    6. Is three months an appropriate grace period from Rule 605's 
reporting requirements for a broker-dealer that has met or exceeded the 
customer account threshold for the first time? Would a shorter or 
longer time period be more appropriate (e.g., one month, two months, or 
six months)? Do commenters agree that a grace period would not be 
necessary for broker-dealers that have previously equaled or exceeded 
the customer account threshold, but subsequently have fallen below the 
threshold and stopped reporting and then need to restart reporting? If 
not, what grace period do commenters think would be appropriate? Would 
one month be sufficient in this context? Are there any other 
circumstances in which a broker-dealer that has met or exceeded the 
customer account threshold would need an additional grace period from 
Rule 605's reporting requirements? Please explain.
    7. Should a broker-dealer that is not a market center be required 
to calculate time of order receipt based on when that broker-dealer 
received the order? Why or why not? Would it be more useful to 
customers or other market participants for a broker-dealer that 
generally routes customer orders to calculate time of order receipt 
based on when that broker-dealer sent the order to a market center for 
execution? Please explain and provide data, if possible.
    8. Should broker-dealers be required to produce all of the detailed 
execution quality statistics set forth in Rule 605? Why or why not? Do 
commenters agree that broker-dealers' customers and other market 
participants would be able to interpret differences in these execution 
quality statistics among reporting entities that may be attributable to 
the context of their different types of business? Do commenters believe 
that there are any additional execution quality statistics that would 
be useful to require of broker-dealers? Please explain and provide 
data, if possible.
    9. Would it be difficult for broker-dealers to obtain any of the 
information needed to calculate the Rule 605 statistics? Why or why 
not? If so, which statistics in particular? Would broker-dealers have 
some or all of the information needed to calculate their Rule 605 
statistics already, including to meet their obligations to assess 
whether they are providing best execution for these orders? Do 
commenters agree that broker-dealers would be able to obtain needed 
information from the execution venues to which they routed the orders 
or publicly available sources? Should the Commission exclude certain 
proposed execution quality statistics that are specific to certain 
order types, such as executable NMLOs? Why or why not? Please explain.

B. Qualified Auction Mechanisms

    Separately, the Commission is proposing rules that generally would 
require that individual investor orders be exposed to order-by-order 
competition in fair and open auctions designed to obtain the best 
prices before such orders could be internalized by wholesalers or any 
other type of trading center that restricts order-by-order 
competition.\197\ Under those proposed rules, a restricted competition 
trading center would not be allowed to execute internally a segmented 
order for an NMS stock until after a broker or dealer has exposed such 
order to competition at a specified limit price in a qualified auction 
that meets certain requirements and is operated by an open competition 
trading center.\198\ An ``open competition trading center'' would be a 
national securities exchange or NMS Stock ATS that meets certain 
requirements, including being transparent and having a substantial 
trading volume in NMS stocks independent of qualified auctions.\199\ A 
``qualified auction'' would be an auction operated by an open 
competition trading center pursuant to specified requirements that are 
designed to achieve competition.\200\
---------------------------------------------------------------------------

    \197\ For a full description and discussion of the order 
competition rule proposal, see Securities Exchange Act Release No. 
96495 (Dec. 14, 2022) (File No. S7-31-22) (Order Competition Rule) 
(``Order Competition Rule Proposal''); proposed Rule 615.
    \198\ See Order Competition Rule Proposal; proposed Rule 
600(b)(87) (defining ``restricted competition trading center''); 
proposed Rule 600(b)(91) (defining ``segmented order''); proposed 
Rule 615(a) (describing the order competition requirement).
    \199\ See Order Competition Rule Proposal; proposed Rule 
600(b)(64) (defining ``open competition trading center'').
    \200\ See Order Competition Rule Proposal; proposed Rule 
600(b)(81) (defining ``qualified auction''); proposed Rule 615(c) 
(setting forth requirements for operation of a qualified auction).
---------------------------------------------------------------------------

    If the Commission adopts the Order Competition Rule Proposal and a 
national securities exchange or NMS Stock ATS that serves as an open 
competition trading center is required to prepare execution quality 
reports under current Rule 605, that national securities exchange or 
NMS Stock ATS would be required to include covered orders that it 
received for execution in a qualified auction within its blended 
executing quality statistics, which also would include trading activity 
outside of the qualified auctions.\201\
---------------------------------------------------------------------------

    \201\ As discussed further below, the Commission is proposing to 
eliminate the separate reporting categories for inside-the-quote 
limit orders, at-the-quote limit orders, and near-the-quote limit 
orders, and create new reporting categories for executable NMLOs and 
beyond-the-midpoint limit orders. See infra sections IV.B.2.(a) and 
IV.B.2.(b). While, as proposed, orders submitted to qualified 
auctions may in many instances be classified as beyond-the-midpoint 
limit orders, this reclassification would not resolve the 
Commission's concern about blending execution quality statistics for 
orders executed in qualified auctions with orders executed outside 
of these auctions.
---------------------------------------------------------------------------

    The Commission is concerned that there may be differences in 
execution quality for orders executed within proposed qualified 
auctions, as compared to other orders executed by market centers 
outside of these qualified auctions, that would not be apparent in 
blended execution quality statistics. For example, orders submitted to 
a qualified auction may be more or less likely to receive price 
improvement, and may have systematically different fill rates, as 
compared to similar orders executed in other trading mechanisms. In 
addition, the Order Competition Rule Proposal would propose both a 
minimum and maximum time period for

[[Page 3802]]

the qualified auction.\202\ Therefore, the time to execution statistics 
for orders submitted to a qualified auction may be systematically 
different from the time to execution statistics of other orders 
executed at a market center. Further, if a market center receives 
covered orders for execution in a qualified auction, then that market 
center would not have discretion about whether to submit these orders 
into a qualified auction and therefore the distinction between orders 
executed by the market center within and outside of a qualified auction 
would not reflect any decision-making on the part of the market center. 
Thus, it would be more useful for market participants to be able to 
review execution quality statistics that are specific to covered orders 
submitted to a qualified auction.
---------------------------------------------------------------------------

    \202\ See Order Competition Rule Proposal; proposed Rule 
615(c)(2).
---------------------------------------------------------------------------

    Accordingly, the Commission is proposing to amend Rule 605(a)(1) to 
state that market centers that operate a qualified auction must prepare 
a separate report pursuant to Rule 605 pertaining only to covered 
orders that the market center receives for execution in a qualified 
auction.\203\ This proposed requirement for separate reports is limited 
to market centers that operate proposed qualified auctions, and would 
not extend to market centers or broker-dealers that route orders away 
for execution in a qualified auction. Therefore, a market center or 
broker-dealer that routes covered orders to an open competition trading 
center for execution within a proposed qualified auction would not be 
required to separately report on or otherwise distinguish orders routed 
to qualified auctions from other types of orders routed away for 
execution in its Rule 605 reports.\204\ In this way, the proposal would 
follow current Rule 605's focus on the overall execution quality that 
the reporting entity provided to all covered orders that it received 
for execution.\205\ Having market centers and broker-dealers report on 
the execution quality provided to orders, regardless of where they are 
executed, would inform market participants and other observers about 
overall execution quality that the market center or broker-dealer is 
able to obtain, including when the market center or broker-dealer 
decides whether and where to route orders to receive such executions. 
Further, distinctions between whether an order was routed to a 
qualified auction or not may depend on the characteristics of the 
order, such as whether it is a segmented order, rather than the 
performance of the market center or broker-dealer that routed the 
order. As such, it would be of more limited utility to have a market 
center or broker-dealer that routes orders to a qualified auction to 
produce a separate Rule 605 report specific to such orders.
---------------------------------------------------------------------------

    \203\ See proposed Rule 605(a)(1).
    \204\ If a larger broker-dealer is also a market center and its 
market center operates a qualified auction mechanism, that aspect of 
the market center would be subject to the separate reporting 
requirement.
    \205\ For example, currently Rule 605 does not require market 
centers to distinguish among covered orders routed to particular 
types of away market centers. Instead, a market center's execution 
quality statistics are blended statistics pertaining to all covered 
orders that the market center received for execution, with the 
limited exception of the statistics for cumulative number of shares 
of covered orders executed at the receiving market center and at any 
other venue. See 17 CFR 242.605(a)(1).
---------------------------------------------------------------------------

    Although market centers and broker-dealers would not be required to 
produce a separate Rule 605 report pertaining to orders that they route 
to a qualified auction, Rule 606 requires routing broker-dealers to 
disclose certain regularly-used execution venues to which they route 
orders, and a report prepared by a broker-dealer pursuant to Rule 606 
would be required to indicate that orders were routed to a particular 
qualified auction.\206\ A customer of a broker-dealer could then 
analyze whether and to what extent the broker-dealer routes to a 
particular market center's qualified auctions (using reports prepared 
pursuant to Rule 606), and evaluate the execution quality provided by 
that market center's qualified auctions (using reports prepared 
pursuant to Rule 605).
---------------------------------------------------------------------------

    \206\ See 17 CFR 242.606(a)(1). For example, if a broker-dealer 
operates an ATS and that ATS has qualified auctions and a continuous 
order book, the broker-dealer's Rule 606 report would be required to 
disclose information about orders that were routed to the ATS's 
qualified auctions separately from orders that were sent directly to 
the ATS's continuous order book.
---------------------------------------------------------------------------

    The Commission considered extending the proposed requirement for 
separate Rule 605 reports beyond proposed qualified auctions to include 
orders submitted to any trading mechanism that seeks to provide 
liquidity to the orders of individual investors. For example, several 
national securities exchanges operate retail liquidity programs.\207\ 
However, in the Order Competition Rule Proposal the Commission is 
proposing a prohibition on certain facilities that are limited, in 
whole or in part, to the execution of segmented orders and this 
prohibition would apply to many of the retail liquidity programs 
currently operated by national securities exchanges.\208\
---------------------------------------------------------------------------

    \207\ Retail liquidity programs are programs for retail orders 
seeking liquidity that allow market participants to supply liquidity 
to such retail orders by submitting undisplayed orders priced at 
least $0.001 better than the exchange's protected best bid or offer. 
Each program results from a Commission approval of a proposed rule 
change made on Form 19b-4 combined with a conditional exemption, 
pursuant to section 36 of the Exchange Act, from 17 CFR 242.612 (the 
``Sub-Penny Rule'') to enable the exchange to accept and rank (but 
not display) the sub-penny orders. See, e.g., Securities Exchange 
Act Release Nos. 85160 (Feb. 15, 2019), 84 FR 5754 (Feb. 22, 2019) 
(SR-NYSE-2018-28) (approving the NYSE retail liquidity program on a 
permanent basis and granting the exchange a limited exemption from 
the Sub-Penny Rule to operate the program); 86194 (June 25, 2019), 
84 FR 31385 (July 1, 2019) (SR-BX-2019-011) (approving Nasdaq BX, 
Inc.'s retail price improvement program on a permanent basis and 
granting the exchange a limited exemption from the Sub-Penny Rule to 
operate the program).
    \208\ See Order Competition Rule Proposal. The Commission 
discusses a number of alternatives in the Order Competition Rule 
Proposal. See id. To the extent that any retail liquidity program is 
retained, separate execution quality statistics specific to orders 
submitted to those programs may be useful to investors.
---------------------------------------------------------------------------

Request for Comment
    The Commission seeks comment on the proposal to require a market 
center that operates a qualified auction to prepare a separate report 
under Rule 605 for covered orders that were submitted to a qualified 
auction if the Order Competition Rule Proposal is adopted. In 
particular, the Commission solicits comment on the following:
    10. Should market centers that operate a proposed qualified auction 
be required to prepare a separate Rule 605 report for covered orders 
that are submitted to their qualified auctions? Why or why not? Do 
commenters agree with limiting this separate reporting requirement to 
market centers that operate a proposed qualified auction, and not to 
either broker-dealers that are not market centers or market centers 
that do not operate a qualified auction? Please explain.
    11. Should this separate reporting requirement be limited to a 
trading mechanism that meets the proposed requirements for a 
``qualified auction''? Would it be more useful if a market center 
prepared a separate report for covered orders submitted to any trading 
mechanism that seeks to provide liquidity to the orders of individual 
investors (e.g., a national securities exchange's retail liquidity 
program), whether or not that trading mechanism operates a ``qualified 
auction''?
    12. Do commenters believe that there are any additional execution 
quality statistics that would be useful to require of a market center 
that operates a proposed qualified auction to facilitate comparison 
among different qualified auctions? For example, would it be useful for 
a market center that operates a proposed qualified auction to provide 
data on any price improvement provided in the qualified auction as

[[Page 3803]]

measured in relation to any additional price matching offered by the 
wholesaler that routed the order to the qualified auction? Please 
explain and provide data, if possible.

C. ATSs and Single-Dealer Platforms

    Currently under Rule 605, firms that operate two separate markets 
must prepare separate reports for each market center.\209\ For example, 
for a firm that acts both as an exchange market maker and as an OTC 
market maker, each function would be considered a separate market 
center and Rule 605 requires the firm to prepare separate reports. The 
requirement to produce separate Rule 605 reports for separate markets 
allows market participants to assess the execution quality of each 
market individually, and prevents differences in the nature of each 
market from obscuring information about execution quality.
---------------------------------------------------------------------------

    \209\ See 17 CFR 242.605(a)(1) (requiring ``every'' market 
center to produce a report). See also Plan, at n.1 (``An entity that 
acts as a market maker in different trading venues (e.g., as 
specialist on an exchange and as an OTC market maker) would be 
considered as a separate market center under the Rule for each of 
those trading venues. Consequently, the entity should arrange for a 
Designated Participant for each market center/trading venue (e.g., 
an exchange for its specialist trading and an association for its 
OTC trading).''). For a description of ``Designated Participant'' as 
defined in the Plan, see supra note 47.
---------------------------------------------------------------------------

    Regulation ATS requires each ATS to register as a broker-
dealer.\210\ Many broker-dealers that operate NMS Stock ATSs have 
separate lines of business that are distinct from their ATSs, yet also 
relate to the trading of NMS stocks.\211\ In addition, one EMSAC 
panelist suggested that the Commission require all ATSs and dark pools 
(i.e., ATSs that do not publish quotations) to report separately from 
their affiliated broker-dealers under Rule 605.\212\ The Commission 
believes there is a need to address directly what Rule 605 requires 
with respect to reporting by firms that operate ATSs. By specifying 
that a broker-dealer that operates an ATS must produce Rule 605 reports 
that are specific to the ATS and separate from the broker-dealer 
operator's other trading activity, the Commission intends to increase 
transparency and regulatory compliance. Accordingly, the Commission 
proposes to specify in Rule 605(a)(1) that ATSs (as defined in 
Regulation ATS \213\) shall prepare reports separately from their 
broker-dealer operators, to the extent such entities are required to 
prepare reports.\214\
---------------------------------------------------------------------------

    \210\ See 17 CFR 242.301(b)(1). 17 CFR 242.301 through 17 CFR 
242.304 is generally known as ``Regulation ATS.''
    \211\ See, e.g., Securities Exchange Act Release No. 83663 (July 
18, 2018), 83 FR 38768, 38771 (Aug. 7, 2018) (Regulation of NMS 
Stock Alternative Trading Systems) (stating that ATSs that trade NMS 
stocks are increasingly operated by multi-service broker-dealers 
that engage in significant brokerage and dealing activities in 
addition to operation of their ATS, and that, for instance, the 
broker-dealer operator of an NMS Stock ATS may also operate an OTC 
market making desk or principal trading desk, or may have other 
business units that actively trade NMS stocks on a principal or 
agency basis in the ATS or at other trading centers).
    \212\ See Healthy Markets II at 2. See also Healthy Markets III 
at 4 (recommending that the Commission modernize and mandate Rule 
605 disclosure for all NMS ATS operators separate and distinct from 
any affiliated broker-dealer). Additionally, a commenter to the 
Concept Release on Equity Market Structure recommended that the 
Commission require all ATSs and dark pools to report under Rule 605. 
See KOR Group I at 3.
    \213\ 17 CFR 242.300 et seq.
    \214\ See proposed Rule 605(a)(1).
---------------------------------------------------------------------------

    Some OTC market makers, such as wholesalers, operate SDPs through 
which they execute institutional orders in NMS stocks against their own 
inventory.\215\ Institutional customers often communicate their trading 
interest using immediate-or-cancel orders (``IOCs'') or IOIs on 
SDPs.\216\ SDPs account for a nontrivial amount of trading volume 
overall (for example, SDPs accounted for approximately 4% of total 
trading volume in Q1 2022) and a significant portion of trading volume 
executed by wholesalers.\217\ Co-mingling SDP activity with other 
market center activity in Rule 605 reports may obscure differences in 
execution quality or distort the general execution quality metrics for 
the market center.\218\ It would be useful if SDPs reported execution 
quality statistics separately from those of their associated broker-
dealer under Rule 605, so that their customers and other market 
participants would be able to distinguish SDP activity from more 
traditional dealer activity. Separate statistics may be particularly 
useful if a dealer provides an SDP (i.e., a separate routing 
destination for the execution of orders) for a particular group of 
customers or type of orders. Therefore, the Commission is proposing to 
require in Rule 605(a)(1) that any market center that provides a 
separate routing destination that allows persons to enter orders for 
execution against the bids and offers of a single dealer shall produce 
a separate report pertaining only to covered orders submitted to such 
routing destination.\219\
---------------------------------------------------------------------------

    \215\ Wholesalers and other OTC market makers either execute 
orders themselves or instead further route the orders to other 
venues. An SDP always acts as the counterparty to any trade that 
occurs on the SDP. See, e.g., Where Do Stocks Trade?, <a href="http://FINRA.org">FINRA.org</a> 
(Dec. 3, 2021), available at <a href="https://www.finra.org/investors/insights/where_do_stocks_trade">https://www.finra.org/investors/insights/where_do_stocks_trade</a> for further discussion.
    \216\ See infra note 615 and accompanying text.
    \217\ See infra notes 618 and 769 and accompanying text.
    \218\ For example, IOC orders typically have different execution 
profiles than other types of orders, including lower fill rates, and 
therefore including orders submitted to a market center's SDP with 
its other orders will effect a downwards skew on the market center's 
fill rates. See infra note 723 and accompanying text; Table 6.
    \219\ See proposed Rule 605(a)(1). To the extent that a 
reporting firm produces more than one Rule 605 report, the firm 
could label each report with the type of business reflected on the 
report. As discussed above, the Commission proposes to expand the 
scope of Rule 605 to include larger broker-dealers. See supra 
section III.A. It is possible that firms would need to prepare 
several Rule 605 reports if they are both a larger broker-dealer and 
a market center and need to prepare more than one report as a market 
center, pursuant to proposed Rule 605(a)(1).
---------------------------------------------------------------------------

Request for Comment
    The Commission seeks comment on the proposal to specify that an ATS 
must produce reports separately from its broker-dealer operator, and to 
require that any market center that provides a separate routing 
destination that allows persons to enter orders against the bids and 
offers of a single dealer must produce separate reports pertaining to 
orders submitted to that routing destination. In particular, the 
Commission solicits comment on the following:
    13. Is it useful for an ATS to produce reports pursuant to Rule 605 
that are specific to covered orders submitted to the ATS and separate 
from orders submitted in connection with other trading activity of its 
broker-dealer operator? Why or why not?
    14. Should a broker-dealer operating an SDP be required to produce 
reports pursuant to Rule 605 that are specific to orders sent to that 
routing destination and separate from other trading activity by that 
dealer, as proposed? Why or why not? Do commenters agree that the 
description of ``a market center that provides a separate routing 
destination that allows persons to enter orders for execution against 
the bids and offers of a single dealer'' accurately describes SDPs? If 
not, what is a more accurate description of an SDP? Please explain.

IV. Proposed Modifications to Scope of Orders Covered and Required 
Information

    Rule 605 reports group orders by both order size and order type, 
and require certain standardized information for all types of orders 
and additional information for market orders and marketable limit 
orders. The Commission is proposing to modify the order size and order 
type groupings, and is proposing to make changes to the required 
information for: all types of orders; market and marketable limit

[[Page 3804]]

order types; and nonmarketable order types. The modifications described 
below would apply to Rule 605 reports produced by all reporting 
entities, including larger broker-dealers.

A. Covered Order

    The Commission proposes to expand the definition of ``covered 
order'' in a number of ways.\220\ The Commission proposes to include 
certain orders received outside of regular trading hours and orders 
submitted with stop prices. Additionally, the Commission is addressing 
whether Rule 605 requires non-exempt short sale orders to be 
incorporated into Rule 605 reporting when a price test restriction is 
in effect for the security.
---------------------------------------------------------------------------

    \220\ See proposed Rule 600(b)(30).
---------------------------------------------------------------------------

1. Orders Submitted Pre-Opening/Post-Closing
    Currently, Rule 605 reports are required to include only orders 
received during regular trading hours \221\ at a time when an NBBO is 
being disseminated. The Commission excluded orders submitted during the 
pre-opening or after the close, among other order types, from the scope 
of reporting because nearly all of Rule 605's statistical measures 
required the availability of the NBBO at the time of order receipt as a 
benchmark.\222\ At the time of adoption, the Commission stated that 
there are substantial differences in the nature of the market between 
regular trading hours and after-hours, and orders executed at these 
times should not be blended together in the same statistics.\223\ 
Similarly, orders for which customers requested special handling, 
including orders to be executed at a market opening price, are excluded 
from Rule 605 reports because their inclusion would skew the general 
statistics.\224\
---------------------------------------------------------------------------

    \221\ ``Regular trading hours'' is defined as the time between 
9:30 a.m. and 4:00 p.m. Eastern Time, or such other time as is set 
forth in the procedures established pursuant to 17 CFR 
242.605(a)(2). See 17 CFR 242.600(b)(77). The Commission is 
proposing to renumber the definition of ``regular trading hours'' as 
proposed Rule 600(b)(91).
    \222\ See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75421.
    \223\ See id., text accompanying note 39. Specifically, the 
Commission stated that the average quoted spread, average effective 
spread, and trade price volatility increased significantly for 
certain securities after the close of regular trading hours. See id. 
at n.39.
    \224\ See id. at 75421.
---------------------------------------------------------------------------

    Market participants submit limit orders prior to market open, and 
these orders are not captured in current Rule 605 reports.\225\ 
Although NMLOs submitted outside of regular trading hours may represent 
a relatively small percentage of NMLO orders overall, pre-open NMLO 
submission volume includes a higher concentration of individual 
investor orders.\226\ In order to provide increased visibility into 
execution quality for individual investor orders, including those 
submitted outside of regular trading hours, the Commission proposes to 
expand the scope of Rule 605 reporting to include certain NMLOs 
submitted outside of regular trading hours if they become executable 
after the opening or reopening of trading during regular trading 
hours.\227\ The Commission is proposing to expand the definition of 
``covered order'' to include any NMLO received by a market center, 
broker, or dealer outside of regular trading hours or at a time when a 
national best bid and national best offer is not being disseminated 
and, if executed, is executed during regular trading hours.\228\ As 
discussed below, the Commission is proposing that NMLOs would be 
benchmarked from the time they become executable rather than the time 
of order receipt.\229\ The executability of limit orders that are 
received while an NBBO is not being disseminated would be determined 
with reference to the opening or re-opening price of the security. This 
would allow market participants to evaluate execution performance for 
NMLOs submitted outside of regular trading hours if they become 
executable during regular trading hours.
---------------------------------------------------------------------------

    \225\ See supra notes 123-125 and accompanying text (commenter 
to 2018 Rule 606 Amendments and petitioner for rulemaking 
recommending inclusion of orders submitted prior to market open).
    \226\ Analysis of CAT data found that NMLOs submitted prior to 
open and designated as only able to execute during regular hours 
make up only a small percentage of order flow when compared to a 
sample 10-minute window of NMLOs submitted during regular hours. 
However, the analysis shows that individual investor orders are 
relatively concentrated in order flow submitted outside of regular 
market hours. Specifically, pre-open submission volume contains a 
larger percentage of individual investor shares than the sample time 
window during regular trading hours, at least for off-exchange 
market centers. See infra notes 672-673 and accompanying text.
    \227\ See proposed Rule 600(b)(20) (defining ``categorized by 
order type'' to include executable NMLOs and executable orders 
submitted with stop prices).
    \228\ See proposed Rule 600(b)(30).
    \229\ See infra section IV.B.2.(a).
---------------------------------------------------------------------------

    The Commission proposes to amend the definition of ``marketable 
limit order'' to specify that the marketability of an order received 
when the NBBO is not being disseminated would be determined using the 
NBBO that is first disseminated after the time of order receipt. 
Specifically, the Commission proposes that an order received at a time 
when a national best bid and national best offer is not being 
disseminated would be a marketable limit order if it is a buy order 
with a limit price equal to or greater than the national best offer at 
the time that the national best offer is first disseminated during 
regular trading hours after the time of order receipt, or if it is a 
sell order with a limit price equal to or less than the national best 
bid time at the time that the national best bid is first disseminated 
during regular trading hours after the time of order receipt.\230\
---------------------------------------------------------------------------

    \230\ See proposed Rule 600(b)(57).
---------------------------------------------------------------------------

    Any limit order received outside of regular trading hours or during 
a trading halt that is marketable based on the first disseminated NBBO 
during regular trading hours after the time of order receipt would not 
be a covered order for purposes of Rule 605.\231\ The Commission's 
proposed definition excludes market orders and marketable limit orders 
submitted prior to open or during a trading halt because such orders 
would generally execute at the opening or re-opening price. Therefore, 
their inclusion in general market and marketable limit order statistics 
would skew both time to execution statistics and other measures of 
execution quality if aggregated with market and marketable limit orders 
received during regular trading hours. While including market and 
marketable limit orders submitted prior to open or during a trading 
halt within the definition of covered order and requiring that the 
execution statistics for these types of orders be reported as a 
separate order type category would avoid the concern about skewed 
statistics, it would add to the complexity of the report.
---------------------------------------------------------------------------

    \231\ For example, a market or marketable limit order that is 
not received by a market center or broker-dealer during regular 
trading hours at a time when the NBBO is being disseminated would 
not be a covered order under proposed Rule 600(b)(30). In addition, 
the covered order definition would continue to exclude any order for 
which the customer requests special handling for execution, 
including orders to be executed at a market opening price, see 
proposed Rule 600(b)(30), and therefore market-on-open (``MOO'') 
orders and limit-on-open (``LOO'') orders would be excluded.
---------------------------------------------------------------------------

    The current definition of covered order includes orders received 
during regular trading hours while an NBBO is being disseminated but 
before the primary listing market has disseminated its first quotations 
in the security. Prior to a primary listing market disseminating its 
first quotations in a security, disseminated quotations often reflect 
spreads that vary significantly from the norm.\232\ To prevent such 
quotations from skewing the execution quality statistics, the 
Commission exempted orders from inclusion in Rule

[[Page 3805]]

605 reports that are received prior to the dissemination of the primary 
listing market's first firm, uncrossed quotations for a trading day 
(``Opening Exemption'').\233\ With respect to orders received during 
regular trading hours but before the primary listing market has 
disseminated its first firm, uncrossed quotation, the Commission 
continues to believe, for the same reasons it granted this exemption, 
that including such orders could distort execution quality statistics. 
Therefore, the Commission is proposing to incorporate this exemptive 
relief into the proposed definition of covered order with respect to 
market or limit orders received during regular trading hours at a time 
when an NBBO is being disseminated.\234\ However, pursuant to the 
proposed amendments to Rule 605, NMLOs (including orders submitted with 
stop prices) received outside of regular trading hours or at a time 
when an NBBO is not being disseminated could be considered covered 
orders, provided the NMLOs were not executed outside of regular trading 
hours.\235\ Inclusion of these orders in Rule 605 reports would be 
useful to market participants, even though such orders necessarily 
would be received before the primary listing market has disseminated 
its first firm, uncrossed quotation and thus fall within the scope of 
the Opening Exemption. Because the Commission is proposing to 
incorporate the exemptive relief reflected in the Opening Exemption 
into the Rule with respect to market or limit orders received during 
regular trading hours, but believes it would be useful to include the 
NMLOs described above in Rule 605 reports, the Commission is also 
proposing to rescind the Opening Exemption.\236\
---------------------------------------------------------------------------

    \232\ See Letter from Annette L. Nazareth, Director, Division of 
Market Regulation to Theodore Karn, President, Market Systems, Inc., 
dated June 22, 2001 (``Market Systems Exemptive Letter'') at 2.
    \233\ See id. (exemption from reporting under Rule 11Ac1-5, the 
predecessor to Rule 605). In addition to the Opening Exemption, the 
Market Systems Exemptive Letter included a separate exemption from 
the Rule for orders received during a time when the consolidated BBO 
reflects a spread that exceeds $1 plus 5% of the midpoint of the 
consolidated BBO (``Spread Width Exemption'').
    \234\ See proposed Rule 600(b)(30).
    \235\ See id.
    \236\ Because the Spread Width Exemption is not inconsistent 
with the proposed amendments to Rule 605, the Commission would not 
rescind the Spread Width Exemption. The Commission continues to 
believe that orders received during a time when the consolidated BBO 
reflects a spread that exceeds $1 plus 5% of the midpoint of the 
consolidated BBO ``could be the result of potentially erroneous 
quotes or of abnormal trading conditions'' and their inclusion 
``could significantly affect the comparability and reliability of 
the execution quality measures in market center monthly reports.'' 
Market Systems Exemptive Letter at 2. The Commission may adopt an 
updated or modified exemption under Rule 605(b) to further refine 
the exemption if, for example, additional factors could be 
considered reliable indicators of orders that could be the result of 
erroneous quotes or abnormal trading conditions. See 17 CFR 
242.605(b).
---------------------------------------------------------------------------

    As a result of the proposed inclusion of limit orders submitted 
after closing and the proposed changes to the categorization of NMLOs 
described in section IV.B.2, limit orders could be received for 
execution and fall within the scope of Rule 605 on a day other than the 
day of order receipt. Under current Rule 605(a)(1), a reporter must 
prepare a monthly report on the covered orders in NMS stocks that it 
received for execution from any person. In order to address this 
scenario, the Commission proposes that a covered order would be 
required to be included in the report for the month in which it becomes 
executable if the day of receipt and the day it initially becomes 
executable occur in different calendar months. Therefore, the 
Commission proposes to amend Rule 605(a)(1) to require a market center, 
broker, or dealer to include in its monthly report, in addition to the 
covered orders in NMS stocks that it received for execution from any 
person, those covered orders in NMS stocks that it received for 
execution in a prior calendar month but which remained open.\237\
---------------------------------------------------------------------------

    \237\ See proposed Rule 605(a)(1).
---------------------------------------------------------------------------

2. Stop Orders
    The definition of ``covered order'' excludes orders with special 
handling instructions, including orders submitted with stop 
prices.\238\ Therefore, orders submitted with stop prices are excluded 
from Rule 605 reports.
---------------------------------------------------------------------------

    \238\ See 17 CFR 242.600(b)(22). Generally, a limit order 
submitted with a stop price becomes a market order when the stop 
price is reached. A stop order to buy becomes a market order when 
the security is bid or trades at or above the specified stop price; 
a stop order to sell becomes a market order when the security is 
offered or trades at or below the specified stop price.
---------------------------------------------------------------------------

    The Commission preliminarily understands that market centers and 
broker-dealers may differ in how they handle stop orders, and the 
current lack of consistent information regarding executions of such 
orders may prevent investors from comparing the execution quality of 
such orders. Further, stop orders are likely to hit their stop prices, 
and are often executed, during periods of price volatility or downwards 
market momentum, which may entail less than favorable execution 
conditions. Given the potential for variation across market centers and 
broker-dealers, as well as the market conditions under which stop 
orders may execute, the Commission believes including stop orders 
within the scope of the Rule would benefit market participants by 
allowing them to analyze these variations in execution quality. 
Further, as stated by the petitioner, including stop orders within the 
Rule's scope would provide a more complete view of the orders certain 
broker-dealers may use when assessing the execution quality market 
centers provide.\239\
---------------------------------------------------------------------------

    \239\ See supra note 123 and accompanying text.
---------------------------------------------------------------------------

    Orders submitted with stop prices are often submitted well before 
their stop prices are reached. In order to provide an ``apples-to-
apples'' comparison of stop orders, the Commission is proposing to 
measure the execution quality of orders submitted with stop prices from 
the time their stop prices are reached, i.e., when such orders become 
executable. As part of the proposed definition of ``executable,'' the 
Commission is proposing to specify that executable means, for any buy 
order submitted with a stop price, that the stop price is equal to or 
greater than the national best bid during regular trading hours, and, 
for any sell orders submitted with a stop price, that the stop price is 
equal to or less than the national best offer during regular trading 
hours.\240\ Incorporation of the ``executable'' concept would have two 
effects. First, stop orders would be reported as part of a Rule 605 
report only if they become executable.\241\ Second, the point that a 
stop order first becomes executable would be used as a benchmark for 
several execution quality metrics, including average effective spread, 
average effective over quoted spread, average realized spread, and 
average time to execution statistics.\242\ The Commission is proposing 
to use the time an order becomes executable rather than the time of 
order receipt based on the understanding that customers, at least for 
purposes of evaluating execution quality of stop orders, would 
generally expect such orders to be executed close in time to when their 
stop prices are triggered. Including executable orders submitted with 
stop prices within the scope of the Rule would help investors compare 
the performance of market centers and broker-dealers from a point in 
time when such orders could reasonably be expected to execute. 
Accordingly, the Commission proposes to rescind the exclusion of orders 
submitted with stop prices within the definition of covered

[[Page 3806]]

order.\243\ As proposed, these orders would comprise a separate order 
type category to help ensure comparability of execution quality 
statistics since, as stated above, stop orders more often may execute 
under volatile or downward-trending market conditions.\244\
---------------------------------------------------------------------------

    \240\ See proposed Rule 600(b)(42). See also infra note 303 and 
accompanying text (discussing the definition of ``executable'' as it 
relates to other non-marketable order types).
    \241\ See proposed Rule 600(b)(20) (defining ``categorized by 
order type'' to include a category for ``executable orders submitted 
with stop prices'') (emphasis added).
    \242\ For further discussion of these metrics, see infra 
sections IV.B.3, IV.B.4.(a), IV.B.4.(b), IV.B.4.(d), and IV.B.6.
    \243\ See proposed Rule 600(b)(30) (eliminating the express 
carve out of orders submitted with stop prices from the definition 
of ``covered order'').
    \244\ See also infra section IV.B.2.a below for more detailed 
description of the changes to categorization by order type, 
including a new category for executable orders with stop prices.
---------------------------------------------------------------------------

3. Non-Exempt Short Sale Orders
    Commission staff has taken the position that staff would view all 
short sale orders that are not marked ``short exempt'' (``non-exempt 
short sale orders'') as special handling orders and, in the staff's 
view, these orders may be excluded from the definition of ``covered 
order'' in Rule 600(b)(15).\245\ Non-exempt short sale orders are 
subject to a price test under Rule 201 of Regulation SHO (``Rule 201'') 
that sets forth a short sale circuit breaker that is triggered in 
certain circumstances, after which time a price restriction will apply 
to short sale orders in that security for that day and the following 
day.\246\ In 2013, Commission staff stated that because in certain 
circumstances non-exempt short sale orders are subject to a price test 
under Rule 201, and the circumstances could vary for different 
securities and different days throughout the month, staff would view 
all non-exempt short sale orders as subject to special handling.\247\
---------------------------------------------------------------------------

    \245\ 17 CFR 242.600(b)(15). See ``Responses to Frequently Asked 
Questions Concerning Rule 605 of Regulation NMS'' (Feb. 22, 2013) 
(``2013 FAQs'').
    \246\ 17 CFR 242.201. Rule 201 generally requires trading 
centers to establish, maintain, and enforce written policies and 
procedures that are reasonably designed to prevent the execution or 
display of a short sale at an impermissible price when a stock has 
triggered a circuit breaker by experiencing a price decline of at 
least ten percent in one day. Once the circuit breaker in Rule 201 
has been triggered, the price test restriction will apply to short 
sale orders in that security for the remainder of the day and the 
following day, unless an exception applies. See 17 CFR 
242.201(b)(1). One exception is for the execution or display of a 
short sale order marked ``short exempt.'' See 17 CFR 
242.201(b)(1)(iii)(B); 17 CFR 242.201(c).
    \247\ See 2013 FAQs.
---------------------------------------------------------------------------

    The Commission preliminarily believes that for purposes of this 
proposal, not all non-exempt short sale orders should be excluded from 
the scope of Rule 605 reporting. When a non-exempt short sale order is 
subject to a price test restriction under Rule 201 of Regulation SHO, a 
trade may only take place at least one tick above the national best 
bid.\248\ These tick-sensitive orders could be ``orders to be executed 
only on a particular type of tick or bid,'' which is one of the types 
of special handling orders specified in the definition of covered 
order.\249\ However, excluding all non-exempt short sale orders from 
Rule 605 reporting, regardless of whether or not a Rule 201 price test 
restriction is in effect, excludes a significant portion of short sale 
orders that are not tick-sensitive. Non-exempt short sale orders do not 
appear to be tick-sensitive the majority of the time because they are 
infrequently subject to a price test restriction. Analysis shows that, 
between April 2015 and March 2022, an event that triggered the Rule 201 
circuit breaker only occurred on 1.7% of trading days for an average 
stock.\250\ The analysis also found that around 18% of trigger events 
occurred the day after a previous trigger event, and around 46% of 
trigger events occurred within a week after a previous trigger event, 
implying that these trigger events tend to be relatively infrequent and 
clustered around a small number of isolated events. Moreover, because 
non-exempt short sale orders are not tick sensitive when a short sale 
price test is not in effect, the inclusion of these orders would not 
skew execution quality statistics.\251\
---------------------------------------------------------------------------

    \248\ See 17 CFR 242.201(b)(1)(i).
    \249\ See 17 CFR 242.600(b)(22).
    \250\ See infra note 662 and accompanying text.
    \251\ In adopting Rule 605, the Commission stated that the 
definition of covered order excludes orders (including short sales 
that must be executed on a particular tick or bid) for which the 
customer requested special handling for execution and that, if not 
excluded, would skew general statistical measures of execution 
quality. See Adopting Release, 65 FR 75414 (Dec. 1, 2000) at 75421.
---------------------------------------------------------------------------

    In addition, including non-exempt short sale orders for which a 
price test restriction is not in effect for the security within Rule 
605 statistics would lead to a more complete picture of reporting 
entities' execution quality, because there is evidence that short sales 
compose a large segment of trades, and likely also order flow. Analysis 
of short volume data shows that, between August 2009 and February 2021, 
short selling constituted an average of 47.3% of trading volume for 
non-financial common stocks.\252\ As discussed further below, evidence 
suggests that hedge funds make up the majority of the short selling 
market, while an academic working paper found that, between January 
2010 and December 2016, around 10.92% of retail trading was made up of 
short sales.\253\
---------------------------------------------------------------------------

    \252\ See infra note 820 and accompanying text.
    \253\ See infra notes 821-827 and accompanying text. See also 
supra note 123 and accompanying text (petitioner recommending 
inclusion of short sales in Rule 605).
---------------------------------------------------------------------------

    Therefore, under the proposal, non-exempt short sale orders would 
not be considered special handling orders unless a price test 
restriction is in effect for the security. Unless another exclusion 
applies, non-exempt short sale orders would fall within the definition 
of covered order and thus within the scope of Rule 605 reporting.\254\ 
Conversely, during a short sale price test, a short sale order not 
marked ``exempt'' would be subject to special handling and would be 
excluded from the definition of covered order and thus from Rule 605 
reporting.
---------------------------------------------------------------------------

    \254\ If an order is otherwise subject to special handling it 
would not be a covered order. See proposed Rule 600(b)(30).
---------------------------------------------------------------------------

Request for Comment
    The Commission seeks comment generally on the proposed expansion of 
Rule 605 reporting requirements to include certain orders received 
outside of regular trading hours and orders submitted with stop prices, 
as well as the proposal to incorporate non-exempt short sale orders 
into Rule 605 unless a price test restriction is in effect for the 
security. In particular, the Commission solicits comment on the 
following:
    15. Should the security's opening or re-opening price be required 
to be used as a benchmark to determine whether a limit order submitted 
outside of regular trading hours is marketable or non-marketable? If 
not, what would be an alternative benchmark? Please explain.
    16. Should the definition of ``covered order'' include NMLOs 
submitted outside of regular trading hours or when the NBBO is not 
being disseminated (i.e., limit orders that are not marketable based on 
the security's opening or re-opening price)? Should market orders and 
marketable limit orders submitted outside of regular trading hours or 
when the NBBO is not being disseminated be included within the 
definition of ``covered order''? Why or why not? Should these orders be 
grouped with other market or marketable limit orders or as new order 
type categories?
    17. Do commenters agree that requiring orders submitted with stop 
prices to be included in Rule 605 reports, and segregating them into 
their own order type category, would avoid distorting execution quality 
statistics? If not, why not?
    18. Do commenters agree that periods when a short sale price test 
is in effect are relatively infrequent and clustered around a small 
number of isolated events? Why or why not?
    19. Should other types of orders be included within the scope of 
covered orders? For example, currently intermarket sweep orders 
(``ISOs'') with a limit price inferior to the NBBO may

[[Page 3807]]

be viewed to be subject to special handling and are excluded from Rule 
605 reports. Should these or other orders types be included within the 
scope of covered orders? If so, please explain any additional 
requirements or conditions that would help ensure comparability of 
order execution quality statistics across reporting entities. For 
example, if a new order type should be within the scope of covered 
orders, should it be a new order type category or be added to an 
existing or proposed order type category (as described in part IV.B.2 
below)?

B. Required Information

    The categories in Rule 605 reports are intended to strike a balance 
between sufficient aggregation of orders to produce statistics that are 
meaningful on the one hand, and sufficient differentiation of orders to 
facilitate fair comparisons of execution quality across market centers 
on the other hand.\255\ When adopting the Rule, the Commission stated 
that its experience with the categories prescribed by the Rule may 
indicate ways in which they could be improved in the future.\256\

1. Categorization by Order Size
    Rule 600(b)(13) defines ``categorized by order size'' as dividing 
orders into separate categories based on the number of shares composing 
an order.\257\ For the purposes of Rule 605 reports, the largest size 
category has bee
