I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change
The Exchange proposes a new Rule 11.5310 governing a Participant's,
Participant Firm's and any Associated Person's best execution
obligations based on Nasdaq PHLX Rule General 9, Section 11 and NYSE
Rule 5310. The proposed rule change is available on the Exchange's
website at <a href="http://www.nyse.com">www.nyse.com</a> and at the principal office of the Exchange.
II. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change
In its filing with the Commission, the self-regulatory organization
included statements concerning the purpose of, and basis for, the
proposed rule change and discussed any comments it received on the
proposed rule change. The text of those statements may be examined at
the places specified in Item IV below. The Exchange has prepared
summaries, set forth in sections A, B, and C below, of the most
significant parts of such statements.
A. Self-Regulatory Organization's Statement of the Purpose of, and the
Statutory Basis for, the Proposed Rule Change
1. Purpose
The Exchange proposes a new Rule 11.5310 (Best Execution) that
would govern a Participant's, Participant Firm's and any Associated
Person's best execution obligations. Proposed Rule 11.5310 is based on
Nasdaq PHLX Rule General 9, Section 11 (Best Execution and
Interpositioning) and NYSE Rule 5310 (Best Execution). The purpose of
the proposed rule is to enhance customer order protection by helping
customers receive efficient executions of their transactions at the
best market prices.
Background and Proposed Rule Change
Nasdaq PHLX Rule General 9, Section 11, adopted in 2010, was based
on NASD Rule 2320.\4\ In 2011, the Financial Industry Regulatory
Authority (``FINRA'') adopted NASD Rule 2320 as FINRA Rule 5310.\5\
Thereafter, on January 5, 2026, the Exchange's affiliate, NYSE, adopted
NYSE Rule 5310 based on the Nasdaq PHLX and FINRA rules.\6\ These rules
require broker-dealers to use ``reasonable diligence'' to ascertain the
best market for a security and execute trades in such market so that
the resultant price to the customer is as favorable as possible under
prevailing market conditions. Other self-regulatory organizations have
similar best execution rules.\7\
---------------------------------------------------------------------------

2010), 75 FR 56633 (September 16, 2010) (SR-PHLX-2010-79) (Order
Approving a Proposed Rule Change, as Modified by Amendment No. 1,
Relating to the Establishment of NASDAQ OMX PSX as a Platform for
Trading NMS Stocks).

(Best Execution and Interpositioning) and Interpretive Material
(``IM'') 2320 as FINRA Rule 5310 in the Consolidated Rulebook)).

New Rule 5310).

---------------------------------------------------------------------------
The Exchange proposes to adopt a new Rule 11.5310 that would govern
the best execution obligations applicable to a Participant, Participant
Firm and any Associated Person based on the Nasdaq PHLX, the NYSE and
other self-regulatory organization rules.
Proposed Rule 11.5310(a)(1) would provide that, in any transaction
for or with a customer or a customer of another broker-dealer, a
Participant, Participant Firm, or Associated Person shall use
``reasonable diligence'' to ascertain the best market for the subject
security and buy or sell in such market so that the resultant price to
the customer is as favorable as possible under prevailing market
conditions. The proposed Rule would identify five factors among those
to be considered in determining whether a Participant, Participant
Firm, or Associated Person has used reasonable diligence:
(1) the character of the market for the security, e.g., price,
volatility, relative liquidity, and pressure on available
communications;
(2) the size and type of transaction;
(3) the number of markets checked;
(4) accessibility of the quotation; and
(5) the terms and conditions of the order which result in the
transaction, as
[[Page 35716]]
communicated to the Participant, Participant Firm, or Associated
Person.\8\
---------------------------------------------------------------------------
\8\ See proposed Rule 25(a)(1)(A)-(E).
---------------------------------------------------------------------------
Except for conforming changes to reflect the Exchange's membership,
proposed Rule 11.5310(a)(1) is based on Nasdaq PHLX Rule General 9,
Section 11(a)(1)(A)-(E) and NYSE Rule 5310(a)(1)(A)-(E) without change.
Proposed Rule 11.5310(a)(2) would prohibit a Participant,
Participant Firm, or Associated Person, in any transaction for or with
a customer or a customer of another broker-dealer, from interjecting a
third party between the Participant, Participant Firm, or Associated
Person and the best market for the subject security in a manner
inconsistent with paragraph (a)(1) of the proposed Rule. Except for
conforming changes to reflect the Exchange's membership, proposed Rule
11.5310(a)(2) is based on Nasdaq PHLX Rule General 9, Section 11(a)(2)
and NYSE Rule 5310(a)(2) without change.
Proposed paragraph (b) would provide that when a Participant or
Participant Firm cannot execute directly with a market maker but must
employ a broker's broker or some other means in order to ensure an
execution advantageous to the customer, the burden of showing the
acceptable circumstances for doing so would be on the retail firm. The
proposed Rule would further provide that examples of acceptable
circumstances would be where a customer's order is ``crossed'' with
another retail firm which has a corresponding order on the other side,
or where the identity of the retail firm, if known, would likely cause
undue price movements adversely affecting the cost or proceeds to the
customer. Except for conforming changes to reflect the Exchange's
membership, proposed Rule 11.5310(b) is based on Nasdaq PHLX Rule
General 9, Section 11(b), and NYSE Rule 5310(b) without change.
Proposed paragraph (c) would provide that failure to maintain or
adequately staff a department assigned to execute customers' orders
cannot be considered justification for executing away from the best
available market; nor can channeling orders through a third party as
described above as reciprocation for service or business serve to
relieve a Participant or Participant Firm of its obligations. The
proposed Rule would further provide that channeling of customers'
orders through a broker's broker or third party pursuant to established
correspondent relationships under which executions are confirmed
directly to the Participant or Participant Firm acting as agent for the
customer, such as where the third party gives up the name of the retail
firm, would not be prohibited if the cost of such service is not borne
by the customer. Except for conforming changes to reflect the
Exchange's membership, proposed Rule 11.5310(c) is based on Nasdaq PHLX
Rule General 9, Section 11(c), and NYSE Rule 5310(c) without change.
Proposed paragraph (d) would provide that a Participant or
Participant Firm through which a retail order is channeled, as
described in the proposed Rule, and which knowingly is a party to an
arrangement whereby the initiating member organization has not
fulfilled its obligations under the proposed Rule, will also be deemed
to have violated the proposed Rule. Except for replacing ``his'' with
``its'' before ``obligations'' in the proposed Rule, proposed Rule 9(d)
is identical to Nasdaq PHLX Rule General 9, Section 11(d). Except for
conforming changes to reflect the Exchange's membership, proposed Rule
11.5310(d) is based on NYSE Rule 5310(d) without change.
Proposed paragraph (e) would provide that the obligations in
paragraphs (a) through (d) of the proposed Rule exist where the
Participant or Participant Firm acts as agent for the account of its
customer but also where retail transactions are executed as principal
and contemporaneously offset. Except for replacing ``his'' with ``its''
before ``customer'' in the proposed Rule, proposed Rule 9(d) is
identical to Nasdaq PHLX Rule General 9, Section 11(e). Except for
conforming changes to reflect the Exchange's membership, proposed Rule
11.5310(e) is based on NYSE Rule 5310(e) without change.
Proposed Rule 11.5310 includes Supplementary Material based on
Nasdaq PHLX Rule General 9, Section 11(f), and the supplementary
material to NYSE Rule 5310 to provide additional guidance and clarity
regarding the obligations of Participants, Participant Firms, or
Associated Persons with respect to best execution requirements.
First, the Exchange would include an introductory paragraph that
provides that proposed Rule 11.5310(a) requires, among other things,
that a Participant, Participant Firm or any Associated Person comply
with paragraph (a) when customer orders are routed to it from another
broker/dealer for execution, and that the proposed Supplementary
Material addresses certain interpretive questions concerning the
applicability of the best execution rule. Except for conforming changes
to reflect the Exchange's membership, the proposed text is based on the
first full paragraph of Nasdaq PHLX Rule General 9, Section 11(f) and
the first full paragraph to the Supplementary Material of NYSE Rule
5310 without change.
Proposed Supplementary Material .01 titled ``Definition of Market''
would define ``market'' and provides that the singular or plural term
should be construed broadly, and it encompasses a variety of different
venues, including, but not limited to, market centers that are trading
a particular security. Proposed Supplementary Material .01 further
provides that the expansive interpretation is meant to both inform
broker-dealers as to the breadth of the scope of venues that must be
considered in the furtherance of their best execution obligations and
to promote fair competition among broker-dealers, exchange markets, and
markets other than exchange markets, as well as any other venue that
may emerge, by not mandating that certain trading venues have less
relevance than others in the course of determining a firm's best
execution obligations. Proposed Supplementary Material .01 is based on
the second full paragraph of Nasdaq PHLX Rule General 9, Section 11(f)
and Supplementary Material .01 of NYSE Rule 5310 without change.
Proposed Supplementary Material .02, titled ``Best Execution and
Executing Brokers,'' would clarify that a Participant's and Participant
Firm's duty to provide best execution in any transaction ``for or with
a customer of another broker-dealer'' does not apply in instances when
another broker-dealer is simply executing a customer order against the
Participant's and Participant Firm's quote or, stated in another
manner, the duty to provide best execution to customer orders received
from other broker-dealers arises only when an order is routed from the
broker-dealer to the Participant or Participant Firm for the purpose of
order handling and execution. As proposed Supplementary Material .02
further provides, the clarification is intended to draw a distinction
between those situations in which the Participant or Participant Firm
is acting solely as the buyer or seller in connection with orders
presented by a broker-dealer against the Participant's or Participant
Firm's quote, as opposed to those circumstances in which the
Participant or Participant Firm is accepting order flow from another
broker-dealer for the purpose of facilitating the handling and
execution of such orders. Except for conforming changes to reflect the
Exchange's membership, proposed Supplementary Material .02 is based on
the third full paragraph of Nasdaq PHLX Rule General 9, Section 11(f),
and Supplementary Material .02 of NYSE Rule 5310 without change.
[[Page 35717]]
Finally, Supplementary Material .03, titled ``Customer Instructions
Regarding Order Handling,'' would specify that if a Participant or
Participant Firm receives an unsolicited instruction from a customer to
route that customer's order to a particular market for execution, the
Participant or Participant Firm is not required to make a best
execution determination beyond the customer's specific instruction.
However, Participants and Participant Firms are still required to
process that customer's order promptly and in accordance with the terms
of the order. Further, where a customer has directed that an order be
routed to another specific broker-dealer that is also a Participant or
Participant Firm, the receiving broker-dealer to which the order was
directed would be required to meet the requirements of proposed Rule
11.5310 with respect to its handling of the order. Proposed
Supplementary Material .03 is identical to Supplementary Material .03
of NYSE Rule 5310, which is based on FINRA Rule 5310.08 without change
except for conforming changes to reflect the Exchange's membership.
2. Statutory Basis
The Exchange believes that the proposed rule change is consistent
with Section 6(b) of the Act,\9\ in general, and furthers the
objectives of Section 6(b)(5) of the Act,\10\ in that it is designed to
prevent fraudulent and manipulative acts and practices, to promote just
and equitable principles of trade, to foster cooperation and
coordination with persons engaged in facilitating transactions in
securities, to remove impediments to and perfect the mechanism of a
free and open market and a national market system and, in general, to
protect investors and the public interest. In addition, the Exchange
believes that the proposed rule change is consistent with the Section
6(b)(5) \11\ requirement that the rules of an exchange not be designed
to permit unfair discrimination between customers, issuers, brokers, or
dealers.
---------------------------------------------------------------------------
\9\ 15 U.S.C. 78f(b).
\10\ 15 U.S.C. 78f(b)(5).
\11\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
In particular, the Exchange believes that adopting best execution
and interpositioning standards based on Nasdaq PHLX Rule General 9,
Section 11 and NYSE Rule 5310 will promote just and equitable
principles of trade and protect investors and the public interest by
imposing consistent order execution standards that Participants,
Participant Firms and Associated Persons must observe when handling
customer orders that directly serve investor protection. Moreover, the
Exchange believes that incorporating the proposed Supplementary
Material containing additional guidance and clarification of the
obligations of Participants, Participant Firms and Associated Persons
under the proposed Rule based on Nasdaq PHLX Rule General 9, Section 11
and NYSE Rule 5310, including the additional provision containing
important clarifications about the interaction between a broker-
dealer's best execution obligations and their obligations with respect
to specific customer instructions based on NYSE Rule 5310 will
potentially enhance compliance with those obligations, thus furthering
the prevention of manipulative acts and practices and the protection of
investors and the public interest.
As discussed in the Purpose section, proposed Rule 11.5310 is
substantially similar to Nasdaq PHLX Rule General 9, Section 11, and
NYSE Rule 5310, thus promoting the application of consistent regulatory
standards for customer order execution across self-regulatory
organizations. As such, the proposed rule change would facilitate rule
harmonization among self-regulatory organizations with respect to
customer order execution, thereby fostering cooperation and
coordination with persons engaged in facilitating transactions in
securities and will remove impediments to and perfect the mechanism of
a free and open market and a national market system. In addition, the
Exchange believes that the proposed rule change will maintain the
necessary protection of customer orders designed to prevent fraudulent
and manipulative acts, without imposing any undue regulatory costs on
industry participants. Finally, the Exchange believes that the proposed
rule change is not designed to permit unfair discrimination between
customers, issuers, brokers and dealers, consistent with Section
6(b)(5) of the Act \12\ because the proposed rule change will impose
the same requirements on all Participants, Participant Firms and
Associated Persons on an equal basis.
---------------------------------------------------------------------------
\12\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
B. Self-Regulatory Organization's Statement on Burden on Competition
The Exchange does not believe that the proposed rule change will
impose any burden on competition that is not necessary or appropriate
in furtherance of the purposes of the Act. The Exchange believes the
proposed rule change will reduce the burdens on Participants,
Participant Firms and Associated Persons that result from their having
to comply with varying rules related to best execution, thus reducing
the complexity of customer order protection rules, particularly for
those Participants, Participant Firms and Associated Persons subject to
the rules of multiple trading venues. Overall, the Exchange believes
the proposed rule change will enhance customer order handling rules by
harmonizing best execution and interpositioning standards across self-
regulatory organizations, which ultimately benefits market participants
and does not impose a burden on competition.
C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others
No written comments were solicited or received with respect to the
proposed rule change.
III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action
The Exchange has filed the proposed rule change pursuant to Section
19(b)(3)(A)(iii) of the Act \13\ and Rule 19b-4(f)(6) thereunder.\14\
Because the proposed rule change does not: (i) significantly affect the
protection of investors or the public interest; (ii) impose any
significant burden on competition; and (iii) become operative for 30
days from the date on which it was filed, or such shorter time as the
Commission may designate, the proposed rule change has become effective
pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6)(iii)
thereunder.
---------------------------------------------------------------------------
\13\ 15 U.S.C. 78s(b)(3)(A)(iii).
\14\ 17 CFR 240.19b-4(f)(6).
---------------------------------------------------------------------------
At any time within 60 days of the filing of such proposed rule
change, the Commission summarily may temporarily suspend such rule
change if it appears to the Commission that such action is necessary or
appropriate in the public interest, for the protection of investors, or
otherwise in furtherance of the purposes of the Act.

change is consistent with the Act. Comments may be submitted by any of
