Equity 6, Section 4 (Exchange Sharing of PSX Participant Risk Settings) 
To Permit the Allocation of Responsibility to Clearing Members

December 18, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on December 10, 2025, Nasdaq PHLX LLC (``PHLX'' or ``Exchange'') filed 
with the Securities and Exchange Commission (``SEC'' or ``Commission'') 
the proposed rule change as described in Items I, II, and III, below, 
which Items have been prepared by the Exchange. The Commission is 
publishing this notice to solicit comments on the proposed rule change 
from interested persons.

I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to amend PHLX Equity 6, Section 4 (Exchange 
Sharing of PSX Participant Risk Settings) to permit the allocation of 
responsibility to clearing members, and to make some technical changes 
to that rule.
    The text of the proposed rule change is available on the Exchange's 
website at <a href="https://listingcenter.nasdaq.com/rulebook/PHLX/rulefilings">https://listingcenter.nasdaq.com/rulebook/PHLX/rulefilings</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 Exchange 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 these 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 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 PHLX Equity 6, Section 4 to permit 
the allocation of responsibility to clearing members. Specifically, the 
Exchange proposes to add a new Section 4(b) (Clearing Member 
Designation) to allow a PSX Participant that does not self-clear to 
allocate responsibility for establishing and adjusting its risk levels 
to a clearing member that clears transactions on behalf of the PSX 
Participant.\3\ A clearing member guarantees transactions executed on 
the Exchange for PSX Participants with whom it has entered into a 
clearing arrangement, and therefore bears the risk associated with 
those transactions. Because a clearing member bears the risk on behalf 
of its associated PSX Participant, the Exchange believes that it is 
appropriate for the clearing member to have knowledge of what risk 
settings the PSX Participant may utilize within the Exchange's trading 
system, as well as the option to set and adjust the risk levels. 
Therefore, the Exchange proposes to make a PSX Participant's risk 
settings in PHLX Equity 6, Section 5 available to a clearing member, as 
well as the option to set and adjust the risk levels, if authorized by 
a PSX Participant.
---------------------------------------------------------------------------

    \3\ The term ``PSX Participant'' has the meaning set forth in 
PHLX Equity 1, Section 1(c).
---------------------------------------------------------------------------

    For clarification, the Exchange does not guarantee that these risk 
controls will be sufficiently comprehensive to meet all of a PSX 
Participant's needs, nor are the controls designed to be the sole means 
of risk management, and using these controls will not necessarily meet 
a PSX Participant's obligations required by Exchange or federal rules--
including, without limitation, Rule 15c3-5 under the Act \4\ (``Rule 
15c3-5''). Use of the Exchange's risk settings in PHLX Equity 6, 
Section 5 will not automatically constitute compliance with Exchange or 
federal rules, and the responsibility for compliance with all Exchange 
and federal rules remains with the PSX Participant.\5\
---------------------------------------------------------------------------

    \4\ 17 CFR 240.15c3-5.
    \5\ See SEC Division of Trading and Markets, Responses to 
Frequently Asked Questions Concerning Risk Management Controls for 
Brokers or Dealers with Market Access (Apr. 15, 2014), available at 
<a href="https://www.sec.gov/rules-regulations/staff-guidance/trading-markets-frequently-asked-questions/divisionsmarketregfaq-0">https://www.sec.gov/rules-regulations/staff-guidance/trading-markets-frequently-asked-questions/divisionsmarketregfaq-0</a>.
---------------------------------------------------------------------------

    If a PSX Participant chooses to designate responsibility to a 
clearing member, the PSX Participant may view any risk levels 
established by the clearing member pursuant to proposed PHLX Equity 6, 
Section 4(b). Even if a clearing member is designated, a PSX 
Participant will continue to be notified by the Exchange of any action 
taken regarding its trading activity. A PSX Participant may revoke the 
responsibility it has allocated to a clearing member at any time.
    The Exchange also proposes labeling current rule PHLX Equity 6, 
Section 4(a) as PHLX Equity 6, Section 4(a) (Sharing Risk Settings). 
Additionally, the Exchange proposes to make a technical correction to 
PHLX Equity 6, Section 4(a). That rule currently refers to ``the 
commentary below,'' but the rule has no associated commentary. What 
happened is that in 2021, as part of a major rulebook reorganization 
effort, the Exchange redesignated PSX Rule 3215 as PHLX Equity 6, 
Section 4 and Section 5.\6\ The text of PSX Rule 3215, minus its 
commentary, was redesignated as PHLX Equity 6, Section 4. Meanwhile, 
the commentary to PSX Rule 3215 was redesignated as PHLX Equity 6, 
Section 5. Therefore, the Exchange proposes substituting the reference 
to ``the commentary below'' in PHLX Equity 6, Section 4(a) with a 
reference to PHLX Equity 6, Section 5. The substance of the newly 
labeled and corrected PHLX Equity 6, Section 4(a) remains unchanged.
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No. 91058 (Feb. 4, 
2021), 86 FR 8966 (Feb. 10, 2021), at 8969 (File No. SR-Phlx-2021-
04) (Self-Regulatory Organizations; Nasdaq PHLX LLC; Notice of 
Filing and Immediate Effectiveness of Proposed Rule Change To 
Relocate Its PSX Equity and General Rules From Its Current Rulebook 
Into Its New Rulebook Shell and Make Other Changes to the Phlx 
Rules).
---------------------------------------------------------------------------

    The Exchange will announce the implementation date of the change 
described in this filing in an Equity Trader Alert at least 30 days 
prior to implementation. At present, the Exchange expects that the 
functionality described in this filing will be ready for implementation 
in the first quarter of 2026, although that time frame is subject to 
change.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\7\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\8\ 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.

    \8\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    As a preliminary matter, the Exchange notes that this proposal is 
not novel. Earlier this year The Nasdaq Stock Market LLC made a 
parallel change to its rulebook.\9\ The language of Nasdaq Equity 6, 
Section 4(b) is substantively identical to the new rule text proposed 
by the Exchange in the present filing.\10\
---------------------------------------------------------------------------

    \9\ See Securities Exchange Act Release No. 103211 (June 9, 
2025), 90 FR 25095 (June 13, 2025) (File No. SR-NASDAQ-2025-043) 
(Self-Regulatory Organizations; The Nasdaq Stock Market LLC; Notice 
of Filing and Immediate Effectiveness of Proposed Rule Change to 
Amend Equity 6, Section 4 (Exchange Sharing of Participant Risk 
Settings) to Permit the Allocation of Responsibility to Clearing 
Members) (``Nasdaq Filing'').
    \10\ As adopted in the Nasdaq Filing, this Nasdaq rule reads as 
follows: ``Clearing Member Designation. A Participant that does not 
self-clear may allocate the responsibility for establishing and 
adjusting the risk levels identified in Equity 6, Section 5 to a 
clearing member that clears transactions on behalf of the 
Participant, if designated in a manner prescribed by the Exchange. A 
Participant that chooses to allocate responsibility to its clearing 
member may view any risk levels established by the clearing member 
pursuant to this Rule, and will be notified of any action taken by 
the Exchange with respect to its trading activity. A Participant may 
revoke responsibility allocated to its clearing member pursuant to 
this paragraph at any time, if designated in a manner prescribed by 
the Exchange.''
---------------------------------------------------------------------------

    The Exchange believes that the proposed amendment to PHLX Equity 6, 
Section 4 would provide clearing members, who have assumed certain 
risks of PSX Participants, greater control over risk tolerance and 
exposure on behalf of their correspondent PSX Participant, while 
helping to ensure that both the PSX Participant and its clearing member 
are aware of developing issues.
    A clearing member guarantees transactions executed on Nasdaq for 
members with whom it has entered into a clearing arrangement, and 
therefore bears the risk associated with those transactions. The 
Exchange therefore believes that it is appropriate for a clearing 
member to have knowledge of what risk settings a PSX Participant may 
utilize within the Exchange's trading system, as well as the option to 
set and

[[Page 60164]]

adjust the risk levels. The proposal will permit a clearing member with 
whom a PSX Participant has entered into a clearing arrangement to 
better monitor and manage the potential risks assumed by the clearing 
member, thereby providing the clearing member with greater control and 
flexibility over setting its own risk tolerance and exposure and aiding 
the clearing member in complying with the requirements of the Act.
    The Exchange also believes that the proposed amendment will assist 
PSX Participants and clearing members in managing their financial 
exposure which, in turn, could enhance the integrity of trading on the 
securities markets and help to ensure the stability of the financial 
system. Moreover, a PSX Participant may revoke responsibility allocated 
to its clearing member at any time.
    The Exchange believes that the proposed rule change does not 
unfairly discriminate among PSX Participants because the use of the 
risk settings under PHLX Equity 6, Section 5 would be available to all 
PSX Participants and their clearing members, if authorized. In 
addition, because all orders on the Exchange pass through the 
Exchange's risk checks, there would be no difference in the latency 
experienced by PSX Participants who have opted to use the risk settings 
versus those who have not opted to use them.\11\
---------------------------------------------------------------------------

    \11\ All Exchange orders pass through basic risk checks 
regardless of whether a PSX Participant opts into a risk setting.
---------------------------------------------------------------------------

    Additionally, the Exchange believes that relabeling PHLX Equity 6, 
Section 4(a) as PHLX Equity 6, Section 4(a) (Sharing Risk Settings), 
and correcting the reference to the ``commentary'' in that rule to its 
current location in PHLX Equity 6, Section 5, are consistent with the 
Act because they make PHLX Equity 6, Section 4 easier to understand and 
navigate, which should aid all PSX Participants in following the rules 
of the Exchange.

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. The proposed rule change is 
designed to provide PSX Participants and their clearing members with 
additional means to monitor and control risk. The proposed rule may 
increase confidence in the proper functioning of the markets and 
contribute to additional competition among trading venues and broker-
dealers. Rather than impede competition, the proposal is designed to 
facilitate more robust risk management by PSX Participants and clearing 
members, which, in turn, could enhance the integrity of trading on the 
securities markets and help to ensure the stability of the financial 
system. Additionally, the changes to PHLX Equity 6, Section 4(a) will 
not have any impact on competition, as they are merely technical in 
nature.

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.

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