Item IV below. The Exchange has prepared summaries, set forth in
sections A, B, and C below, of the most significant aspects of such
statements.
A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change
1. Purpose
The Exchange proposes to amend Equity 11, Rule 11890 (Clearly
Erroneous Transactions) in light of the Commission's approval of
Overnight Protected Bands under the LULD Plan for 23/5 Trading.
Background
In conjunction with the industry's plans for the introduction of
trading 23 hours a day, 5 days a week (``23/5 Trading''), the Operating
Committee of the Plan to Address Extraordinary Market Volatility
(``LULD Plan'') filed proposed Amendment 27 to the LULD Plan, which
proposed to establish price band protections during overnight trading
hours (``Overnight Price Bands'').\3\ The Operating Committee proposed
that the Overnight Price Bands would initially be temporary static
bands 20% above and below two reference points, and that after
implementation, the Operating Committee would evaluate the performance
of such Overnight Price Bands and propose appropriate changes in a new
plan amendment.\4\ On August 5, 2026, the Commission approved the
proposal.\5\
---------------------------------------------------------------------------
\3\ See Securities Exchange Act Release No. 105596 (June 1,
2026), 91 FR 33774 (June 4, 2026) (File No. 4-631) (Notice of Filing
of 27th Amendment to the National Market System Plan).
\4\ See id.
\5\ See Securities Exchange Act Release No. 106042 (August 5,
2026), 91 FR 51515 (August 10, 2026) (File No. 4-631) (Order
Granting Approval of the 27th Amendment to the National Market
System Plan to Address Extraordinary Market Volatility to Establish
Temporary Price Band Protections in Overnight Trading).
---------------------------------------------------------------------------
In light of the Commission's approval of these changes to the LULD
Plan, the Exchange now proposes several amendments to Rule 11890
regarding Clearly Erroneous Transactions. In general, the rule
describes the process a market participant may use to request
cancellation of a transaction that was ``clearly erroneous.'' The
current rule's central premise is that if LULD Price Bands under the
LULD Plan were available and correct at the time the transaction was
executed, the transaction is not eligible for clearly erroneous review.
Specifically, Rule 11890(a)(2)(C)(1) currently provides that ``[i]f the
execution time of the transaction(s) under review is during Market
Hours, the transaction will not be reviewable as clearly erroneous''
except in certain limited circumstances, including when (A) the
transaction is in an NMS stock that is not subject to the LULD Plan
(e.g., rights and warrants), (B) the transaction was executed at a time
with LULD Price Bands were unavailable or trading should have been
prevented due to a regulatory halt or other halt, or (C) several other
limited circumstances.\6\ In approving the existing version of the
rule, the Commission noted that restricting clearly erroneous review in
this way during times when LULD Price Bands were in effect was
``consistent with the Act and will further the goal of providing
greater certainty to market participants that trades executed within
the Price Bands will stand and not be broken. . . . Thus, the proposal
is designed to limit the potential discordance between the LULD
mechanism and CEE review process.'' \7\
---------------------------------------------------------------------------
\6\ See Rule 11890(a)(2)(C)(1)(i), (ii), and (iii).
\7\ See Securities Exchange Act Release No. 95658 (September 1,
2022), 87 FR 55060 at 55063 (September 8, 2022) (SR-CboeBZX-2022-
037) (Order Approving a Proposed Rule Change, as Modified by
Amendment Nos. 1 and 2, to Amend BZX Rule 11.17, Clearly Erroneous
Executions).
---------------------------------------------------------------------------
Currently, LULD Price Bands are available only during Market Hours,
meaning that the restrictions on clearly erroneous review described
above apply only during Market Hours. With the introduction of
Overnight Price Bands, the Exchange now proposes to extend the existing
restrictions on clearly erroneous review to the period when Overnight
Price Bands are in place. This proposed change would be consistent with
the Commission's rationale in approving the current version of the rule
because it would limit any potential discordance between the LULD
mechanism and CEE review in the overnight trading session, providing
greater certainty to market participants that trades executed with the
Overnight Price Bands will stand and not be broken.
Proposed Changes to Rule 11890(a)(2)(C)(1)
To implement this change, the Exchange proposes to add several
definitions to Rule 11890(a)(2)(C)(1). First, the Exchange would add
that the term ``LULD Protected Hours'' includes Market Hours and
``Overnight Protected Hours'' defined in Section VIII of the LULD Plan.
Second, the Exchange would define ``LULD Price Bands'' or ``Price
Bands'' to mean the Price Bands defined in Section V of the LULD Plan
(i.e., the Price Bands that apply during Market Hours) and ``Overnight
Price
[[Page 64997]]
Bands'' as defined in Section VIII of the LULD Plan (i.e., the Price
Bands that apply to the Overnight Protected Hours from 9:00 p.m. ET
through 4:00 a.m. ET).
The Exchange proposes to amend the current first sentence of Rule
11890(a)(2)(C)(1) to replace the phrase ``Market Hours'' with ``LULD
Protected Hours,'' to provide that ``[i]f the execution time of the
transaction(s) under review is during LULD Protected Hours, the
transaction will not be reviewable as clearly erroneous . . . .'' This
change would extend the LULD-based restrictions on clearly erroneous
review currently in place during Market Hours to the Overnight
Protected Hours.
The Exchange also proposes to amend Rule 11890(a)(2)(C)(1)(ii)'s
reference to ``Percentage Parameter'' to incorporate the Percentage
Parameter that applies to Overnight Protected Hours. The amended
provision would provide for the applicability of clearly erroneous
review if the price of the transaction to buy (sell) that is the
subject of the clearly erroneous complaint is greater than (less than)
the Reference Price by an amount that equals or exceeds the applicable
Percentage Parameter defined in Appendix A to the LULD Plan (with
respect to the Price Bands that apply during Market Hours) or the
``Overnight Percentage Parameter defined in Section VIII of the LULD
Plan'' (with respect to Overnight Protected Hours).
In addition to these changes, the Exchange also proposes to make a
non-substantive change to Rule 11890(a)(2)(C)(1)(i), substituting the
term ``LULD Plan'' for the current text ``the Plan to Address
Extraordinary Market Volatility Pursuant to Rule 608 of Regulation NMS
under the Act (the `Limit Up-Limit Down Plan' or `LULD Plan,')'' as the
``LULD Plan'' would be defined in the proposed revision to Rule
11890(a)(2)(C)(1).
Proposed Changes to 11890(a)(2)(A)(iii), (a)(2)(C)(2), (a)(2)(D)(3),
and (b)(i)
As noted above, current Rule 11890(a)(2)(C)(1) permits clearly
erroneous review even during Market Hours when the transaction in
question is in an NMS Stock that is not subject to the LULD Plan, i.e.,
rights and warrants. Such transactions are reviewed for clearly
erroneous status using the procedures set out in Rule
11890(a)(2)(C)(2), including the Numerical Guidelines set out in the
table accompanying Rule 11890(a)(2)(C)(2)(i). The Exchange now proposes
to introduce a similar provision regarding transactions in NMS Stocks
not subject to the LULD Plan that are executed during the Overnight
Protected Hours; such transactions would be subject to the same
Numerical Guidelines as transactions occurring in Pre-Market Hours and
Post-Market Hours.
The heading of Rule 11890(a)(2)(C)(2) addresses ``[r]eview of
transactions occurring during Pre-Market Hours and Post-Market Hours or
eligible for review pursuant to paragraph (c)(1)(i).'' The Exchange
proposes to replace the phrase ``eligible for review pursuant to
paragraph (c)(1)(i)'' (which, in the current rule, means transactions
executed during Market Hours in NMS Stocks not subject to the LULD
Plan) with ``during LULD Protected Hours in NMS Stocks not subject to
the LULD Plan.'' This proposed language would cover transactions in NMS
Stocks not subject to the LULD Plan in Market Hours and expand the same
treatment to transactions executed in NMS Stocks not subject to the
LULD Plan during Overnight Protected Hours. As such, the proposed
change is not novel.
The Exchange proposes to make the same change everywhere else such
language appears in the rule--namely, in the text of paragraphs
(a)(2)(A)(iii), (a)(2)(C)(2)(i), (a)(2)(C)(2)(ii), (a)(2)(C)(2)(iii),
(a)(2)(D)(3), and (b)(i).\8\ In each case, the Exchange proposes to
replace the phrase ``transactions occurring during Pre-Market Hours or
Post-Market Hours or eligible for review'' pursuant to subparagraph
(C)(1)(i) with ``transactions occurring during Pre-Market Hours or
Post-Market Hours or during LULD Protected Hours in NMS Stocks not
subject to the LULD Plan.''
---------------------------------------------------------------------------
\8\ Paragraphs (a)(2)(A)(iii), (a)(2)(C)(2)(i),
(a)(2)(C)(2)(ii), and (a)(2)(C)(2)(iii) specify general rules for
applying clearly erroneous review to transactions where such review
is not precluded by paragraph (a)(2)(C)(1). Paragraph (a)(2)(D)(3)
specifies conditions where the Exchange may use a revised Reference
Price for the purpose of clearly erroneous review in certain
transactions where such review is not precluded by paragraph
(a)(2)(C)(1). Paragraph (b)(i) specifies that for transactions where
clearly erroneous review is not precluded by paragraph (a)(2)(C)(1),
a senior officer may initiate clearly erroneous review on his or her
own motion.
---------------------------------------------------------------------------
The Exchange also proposes to make corresponding changes to the
headings of the table accompanying Rule 11890(a)(2)(C)(2)(i). The
Exchange proposes to change the heading of the second column from
``Market Hours Numerical Guidelines for transactions eligible for
review pursuant to subparagraph (C)(1)(i)'' to ``Numerical Guidelines
for Transactions Executed During Market Hours in NMS Stocks Not Subject
to the LULD Plan.'' This change would simply replace the shorthand
``eligible for review pursuant to subparagraph (C)(1)(i)'' with the
fuller description that such transactions are ``executed during Market
Hours in NMS Stocks not subject to the LULD Plan,'' and is not a
substantive change.
Similarly, the Exchange proposes to change the heading of the third
column from ``Pre-Market Hours and Post-Market Hours Numerical
Guidelines'' to ``Numerical Guidelines for Transactions Executed During
Pre-Market Hours and Post-Market Hours or During Overnight Protected
Hours in NMS Stocks Not Subject to the LULD Plan.'' The proposed change
addresses the fact that transactions executed during Overnight
Protected Hours in NMS Stocks not subject to the LULD Plan are eligible
for clearly erroneous review--just as are transactions in NMS Stocks
not subject to the LULD Plan executed during Market Hours--but at the
Numerical Guidelines that apply outside of Market Hours.
Together, these proposed changes would extend the eligibility of
clearly erroneous review for transactions in NMS Stocks not subject to
the LULD Plan that is currently in place during Market Hours to the
Overnight Protected Hours, and would apply the Commission's recent
approval of Overnight Price Bands to the clearly erroneous executions
rule.
Implementation
The Exchange understands that the other national securities
exchanges and FINRA will also file similar proposals, the substance of
which are identical to this proposal. The Exchange proposes that this
rule change would become operative at the commencement of 23/5 Trading,
which is scheduled to commence industry-wide on December 6, 2026.
2. Statutory Basis
The Exchange believes that its proposal 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 particular, in that it is designed to
promote just and equitable principles of trade, 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.
---------------------------------------------------------------------------
\9\ 15 U.S.C. 78f(b).
\10\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
The Exchange believes that the proposed change is consistent with
just and equitable principles of trade because it extends the basic
premise of the current rule that clearly erroneous review should be
generally unavailable any time a transaction is executed within LULD
Price Bands at a time the
[[Page 64998]]
Price Bands were available and correct. Currently, LULD Price Bands are
available only during Market Hours, meaning that the restrictions on
clearly erroneous review described above apply only during Market
Hours. With the introduction of Overnight Price Bands, the Exchange
believes that extending such restrictions on clearly erroneous review
to the period when Overnight Price Bands are in place would remove
impediments to and perfect the mechanism of a free and open market and
a national market system by enhancing the transparency and consistency
of the rule.
The resulting rule would thus extend the LULD-related limits on
clearly erroneous review that are applicable in Market Hours to the
overnight period. The proposed change would also be consistent with the
Commission's rationale in approving the current version of the rule
because it would limit any potential discordance between the LULD
mechanism and CEE review in the overnight trading session, providing
greater certainty to market participants that trades executed with the
Overnight Price Bands will stand and not be broken.\11\
---------------------------------------------------------------------------
\11\ See 87 FR 55060 at 55063, supra note 7.
---------------------------------------------------------------------------
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 not necessary or appropriate in
furtherance of the purposes of the Act. Rather than impacting
competition, the proposed change would simply extend the basic premise
of the current rule that clearly erroneous review should be generally
unavailable any time a transaction is executed within LULD Price Bands
at a time the Price Bands were available and correct. The Exchange
understands that the other national securities exchanges and FINRA will
also file similar proposals, the substance of which are identical to
this proposal. Thus, the proposed rule change will help to ensure
consistency across SROs without implicating any competitive issues.
C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others
No written comments were either solicited or received.
III. Date of Effectiveness of the Proposed Rule Change and Timing for
Commission Action
Because the foregoing 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, it has become
effective pursuant to Section 19(b)(3)(A)(iii) of the Act \12\ and
subparagraph (f)(6) of Rule 19b-4 thereunder.\13\
---------------------------------------------------------------------------
\12\ 15 U.S.C. 78s(b)(3)(A)(iii).
\13\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)
requires a self-regulatory organization to give the Commission
written notice of its intent to file the proposed rule change at
least five business days prior to the date of filing of the proposed
rule change, or such shorter time as designated by the Commission.
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------
At any time within 60 days of the filing of the 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. If the Commission
takes such action, the Commission shall institute proceedings to
determine whether the proposed rule should be approved or disapproved.
IV. Solicitation of Comments

arguments concerning the foregoing, including whether the proposed rule
change is consistent with the Act. Comments may be submitted by any of
