[[Page 59290]]
A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change
1. Purpose
NYSE American LLC (``NYSE American'' or the ``Exchange'') proposes
to amend Rule 7.12E (``Trading Halts Due to Extraordinary Market
Volatility'') concerning the resumption of trading following a Level 3
market-wide circuit breaker (``MWCB'') halt (``Level 3 Market
Decline'') in connection with the industry's expansion of trading hours
to 23 hours per day, 5 days per week (``23/5 Trading''). Some
exchanges, including the Exchange's affiliate exchange, NYSE Arca, Inc.
(``NYSE Arca''), are planning to offer overnight trading,\3\ and as a
result, the uniform Level 3 Market Decline rules of each exchange are
being modified, as explained further below.
---------------------------------------------------------------------------
\3\ See, e.g., Securities Exchange Act Release No. 105532 (May
21, 2026), 91 FR 31509 (May 27, 2026) (SR-NYSEARCA-2026-53) (``NYSE
Arca 23/5 Trading Notice''). The Exchange does not intend to
implement 23/5 Trading at this time.
---------------------------------------------------------------------------
Background
The MWCB mechanism under Rule 7.12E provides an important,
automatic mechanism that is invoked to promote stability and investor
confidence during a period of significant stress when U.S. securities
markets experience extreme broad-based declines. All U.S. equity
exchanges and FINRA (collectively, the self-regulatory organizations or
``SROs'') adopted uniform rules relating to the MWCB mechanism in 2012,
which are designed to slow the effects of extreme price movement
through coordinated trading halts across U.S. securities markets when
severe price declines reach levels that may exhaust market
liquidity.\4\ Such market-wide circuit breakers provide for trading
halts in all U.S. cash equity and equities options markets during a
severe market decline as measured by a single-day decline in the S&P
500 Index during regular trading hours.
---------------------------------------------------------------------------
\4\ See Securities Exchange Act Release No. 67090 (May 31,
2012), 77 FR 33531 (June 6, 2012) (SR-BATS-2011-038; SR-BYX-2011-
025; SR-BX-2011-068; SR-CBOE-2011-087; SR-C2-2011-024; SR-CHX-2011-
30; SR-EDGA-2011-31; SR-EDGX-2011-30; SR-FINRA-2011-054; SR-ISE-
2011-61; SR-NASDAQ-2011-131; SR-NSX-2011-11; SR-NYSE-2011-48; SR-
NYSEAmex-2011-73; SR-NYSEArca-2011-68; SR-Phlx-2011-129) (``MWCB
Approval Order'').
---------------------------------------------------------------------------
Pursuant to Rule 7.12E, a market-wide trading halt will be
triggered if the S&P 500 Index declines in price by specified
percentages from the prior day's closing price of that index.
Currently, the triggers are set at three circuit breaker thresholds: 7%
(Level 1), 13% (Level 2), and 20% (Level 3). A market decline that
triggers a Level 1 or Level 2 halt after 9:30 a.m. ET and before 3:25
p.m. ET would halt market-wide trading for 15 minutes, while a similar
market decline at or after 3:25 p.m. ET would not halt market-wide
trading. If a Level 3 Market Decline occurs at any time during the
trading day, trading in all stocks will halt on the Exchange for the
remainder of the trading day, and will resume the following trading day
at 7:00 a.m. ET.
Proposal
The Exchange now proposes to amend Rule 7.12E to reflect extended
trading hours under 23/5 Trading. On December 6, 2026, several
exchanges, including NYSE Arca, intend to offer new overnight trading
sessions that would be available from 9:00 p.m. ET to 4:00 a.m. ET,
significantly increasing their hours of operation in response to
customer demand.
As discussed, consistent with the uniform rules in place across all
SROs, current Rule 7.12E(b)(ii) provides that if a Level 3 Market
Decline occurs at any time during the trading day, the Exchange shall
halt trading in all stocks on the Exchange for the remainder of the
trading day. Currently, that means that the earliest that any exchange
would re-open trading after a Level 3 Market Decline is 4:00 a.m. ET
the following day, since no SROs are open for trading before 4:00 a.m.
ET.
Unless amended, when 23/5 Trading is launched, the current rule's
reference to halting ``for the remainder of the trading day'' \5\ would
require SROs participating in 23/5 Trading to re-open trading at an
earlier time, i.e., 9:00 p.m. ET on the same calendar day, when those
SROs' systems would generally become available for overnight trading.
The Exchange does not believe that this is an expected or desired
result and is therefore amending this rule in coordination with the
other SROs such that trading on any SRO will not resume until 4:00 a.m.
ET or later on the following trading day, consistent with current
market practice. This proposed rule change is therefore not intended to
make any substantive changes to the MWCB mechanism. Rather, the
proposed rule change would preserve the current resumption time
following a Level 3 Market Decline.
---------------------------------------------------------------------------
\5\ See Rule 7.12E(b)(ii).
---------------------------------------------------------------------------
To effect this change, the Exchange proposes to delete the language
in Rule 7.12E(b)(ii) that provides that trading in all stocks will halt
on the Exchange ``for the remainder of the trading day'' if a Level 3
Market Decline occurs at any time during the trading day, and replace
it with new language that explicitly provides that trading in all
stocks would halt on the Exchange until 4:00 a.m. ET or later on the
following trading day.
2. Statutory Basis
The Exchange believes that its proposal is consistent with Section
6(b) of the Act,\6\ in general, and furthers the objectives of Section
6(b)(5) of the Act,\7\ 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.
---------------------------------------------------------------------------

\7\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
The MWCB mechanism described in Rule 7.12E is an important,
automatic mechanism that is invoked to promote stability and investor
confidence during periods of significant stress when U.S. securities
markets experience extreme broad-based declines. The proposed rule
change, when applied uniformly by all SROs, would ensure that the
current 4:00 a.m. ET resumption time following a Level 3 halt continues
to apply under 23/5 Trading, notwithstanding current rule text implying
that the resumption time would coincide with the start of overnight
trading on SROs operating an overnight session.
Rather than leave the rule in place as is, which would result in an
earlier resumption time than originally contemplated when the rule was
adopted, the Exchange, the other U.S. equity exchanges, and FINRA met
alongside industry representatives to determine the appropriate
resumption time. Following those discussions, the collective decision
was made to retain the 4:00 a.m. ET resumption time, notwithstanding
the fact that an earlier resumption time would be possible with the
introduction of 23/5 Trading. The proposed rule change codifies this
decision into the Exchange's rules. The Exchange understands that the
other SROs will also be filing similar proposed rule changes. As a
result, the market as a whole, including on- and off-exchange, will
continue to be subject to harmonized rules for the resumption of
trading following a Level 3 Market Decline.
While the SROs had previously decided to tie the resumption time
following a Level 3 halt to the earliest SRO opening time, the upcoming
transition to 23/5 Trading raises various concerns that warrant a
change from the current approach.
First, the Exchange notes that the MWCB mechanism was designed to
[[Page 59291]]
provide a cooling-off period where market participants would be
provided with additional time to evaluate the market events that led to
the decline before determining how to position their trading activity
for the next day. With the introduction of 23/5 Trading and the start
of overnight trading on some SROs at 9:00 p.m. ET, however, this
cooling-off period could be materially shortened, reducing one of the
key benefits that the MWCB mechanism was designed to provide in the
first place. Rather than shorten the cooling-off period and risk this
benefit, the Exchange believes the market would be better served by a
change to the length of the associated trading halt that mirrors
current market practice. Under the proposed rule, as is the case today,
after a Level 3 halt, all SROs would re-open trading at 4:00 a.m. ET or
later, and no SRO would offer an overnight trading session starting on
the day of a Level 3 halt.
Second, overnight trading may be subject to different liquidity and
participation considerations than the current pre-market sessions that
start at or after 4:00 a.m. ET. Notably, while retail investors have
expressed interest in overnight trading, the Exchange expects that
institutional investors will take more time to transition to a round-
the-clock model. However, such institutional participation may be of
heightened importance following a Level 3 halt, as these investors are
likely to have views on the underlying market events that led to the
Level 3 Market Decline in the first place. The Exchange is concerned
that opening during hours that such participants do not normally trade
may impact the quality of price discovery at a time of significant
market volatility. Waiting until 4:00 a.m. ET to resume trading would
facilitate broader participation and therefore price discovery.
Finally, the Exchange notes that the Commission recently approved
an amendment to the Plan to Address Extraordinary Market Volatility
(``LULD Plan'') that would establish new price protections from 9:00
p.m. ET to 4:00 a.m. ET.\8\ While these price bands would help to
assure a fair and orderly market during normal market conditions, it is
possible that they would instead prevent normal price discovery
following a Level 3 Market Decline. Rather than allowing trading to
resume with such price bands in effect, which would represent a change
from the current trading reopening following a Level 3 Market Decline,
the Exchange believes that requiring SROs to wait until 4:00 a.m. ET or
later to resume trading would ensure that price discovery can occur
unimpeded during pre-market trading, as it does today, which may
further inform prices going into the opening auction and regular market
hours trading following a Level 3 halt.
---------------------------------------------------------------------------
\8\ See Securities Exchange Act Release No. 106042 (August 5,
2026), 91 FR 51515 (August 10, 2026) (Order Granting Approval of the
Twenty-Seventh Amendment to the National Market System Plan to
Address Extraordinary Market Volatility to Establish Temporary Price
Band Protections in Overnight Trading).
---------------------------------------------------------------------------
Given the factors discussed above, the Exchange believes that
trading in all securities on the Exchange should not resume before 4:00
a.m. ET on the trading day after a Level 3 halt. This decision, which
the Exchange understands will also be reflected in the rules of the
other SROs, would promote a fair and orderly market at a time of
significant market volatility, and thereby protect investors and the
public interest. In addition, while the actual Level 3 resumption time
would not be changing in practice--as proposed, the current resumption
time and future resumption time would both be 4:00 a.m. ET at the
earliest--the Exchange believes that it is appropriate to amend its
rules to ensure that its rules reflect the upcoming changes due to 23/5
Trading. Without this change, market participants may mistakenly
believe that the Exchange intends for trading to re-open on overnight
trading exchanges at 9:00 p.m. ET following a Level 3 halt. The
proposed rule change would therefore facilitate operational
transparency while providing for a fair and orderly market.
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 because the proposal would
ensure the continued, uninterrupted operation of a consistent mechanism
to halt trading across U.S. securities markets. Further, the Exchange
understands that the other SROs intend to file proposed rule changes to
ensure a consistent resumption time at 4:00 a.m. or later ET across
markets. Thus, the proposed rule change will help to ensure consistency
across market centers 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 solicited or received with respect to the
proposed rule change.
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 \9\ and
subparagraph (f)(6) of Rule 19b-4 thereunder.\10\
---------------------------------------------------------------------------
\9\ 15 U.S.C. 78s(b)(3)(A)(iii).
\10\ 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

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