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 Interpretation and Policy .01 to
Exchange Rule 1801 to update the table of reporting authorities \3\ for
indexes on which the Exchange may list and trade options. In
particular, the Exchange proposes to amend the name of the ``Bloomberg
US Large Cap Price Return Index'' (the ``B500 Index'') to ``Bloomberg
500 Index,'' due to Bloomberg Index Services Limited (``BISL'')
rebranding the B500 Index under the new name ``Bloomberg 500
Index''.\4\
---------------------------------------------------------------------------
\3\ The term ``reporting authority'' with respect to a
particular index means the institution or reporting service
designated by the Exchange as the official source for (1)
calculating the level of the index from the reported prices of the
underlying securities that are the basis of the index and (2)
reporting such level. The reporting authority for each index
approved for options trading on the Exchange shall be Specified (as
provided in Rule 1800) in the Interpretations and Policies to Rule
1801. See Exchange Rule 1801(q).
\4\ See Index Announcement, Bloomberg US Large Cap Index To Be
Renamed Bloomberg 500 Index, available at <a href="https://assets.bbhub.io/professional/sites/27/Bloomberg-US-Large-Cap-Index-To-Be-Renamed-Bloomberg-500-Index.pdf">https://assets.bbhub.io/professional/sites/27/Bloomberg-US-Large-Cap-Index-To-Be-Renamed-Bloomberg-500-Index.pdf</a> (last visited July 11, 2025).
---------------------------------------------------------------------------
On March 10, 2025, the Exchange filed its proposal with the
Securities and Exchange Commission (the ``Commission'') to amend
certain of the Exchange's rules in connection with the Exchange's plan
to list and trade options on the B500 Index.\5\ The B500 Index is a
broad-based, float \6\ market-capitalization-weighted benchmark of the
500 most highly capitalized U.S.-listed companies.\7\ All constituents
of the B500 Index \8\ are securities consisting of common stocks, real
estate investment trusts (``REITs''), and tracking stocks, which are
primarily listed on a U.S. securities exchange, as provided for in the
Methodology Guide.\9\ The components of the B500 Index are determined
from the U.S.-listed companies that have the largest cumulative free-
float market capitalization. Each component security of the B500 Index
must also meet certain minimum eligibility and liquidity screening
requirements, as detailed in the Methodology Guide.\10\ Since the
Commission issued the B500 Approval Order and to date, the Exchange has
not listed options for trading on the B500 Index for business
reasons.\11\
---------------------------------------------------------------------------
\5\ See Securities Exchange Act Release No. 102959 (April 30,
2025), 90 FR 19236 (May 6, 2025) (SR-MIAX-2025-08) (Order Granting
Approval of a Proposed Rule Change To Amend Certain MIAX Options
Exchange Rules To Permit the Listing and Trading of Options on the
Bloomberg US Large Cap Price Return Index) (the ``B500 Approval
Order'').
\6\ As part of the construction of the B500 Index, BISL, the
administrator of the B500 Index, performs a liquidity screening for
each component security that is initially eligible to be included in
the B500 Index. Part of the liquidity screening process involves
removing all securities from the B500 Index that failed the minimum
free-float shares screening. Free-float shares are used in
calculation of the B500 Index. BISL calculates the free-float shares
figure by subtracting shares held by insiders and those deemed to be
stagnant shareholders from the shares outstanding. Securities should
have free-float market capitalization equal to or greater than 50%
of the equity universe minimum size requirement (total market
capitalization) to be included in the index. See Bloomberg US
Domestic Equity Indices Methodology, at page 6, dated September
2024, available at <a href="https://assets.bbhub.io/professional/sites/10/Bloomberg-US-Domestic-Equity-Indices-Methodology.pdf">https://assets.bbhub.io/professional/sites/10/Bloomberg-US-Domestic-Equity-Indices-Methodology.pdf</a> (the
``Methodology Guide'').
\7\ See Bloomberg US Large Cap Index Fact Sheet, dated March 31,
2025, available at <a href="https://assets.bbhub.io/professional/sites/27/Bloomberg-US-Large-Cap-Index-Fact-Sheet.pdf">https://assets.bbhub.io/professional/sites/27/Bloomberg-US-Large-Cap-Index-Fact-Sheet.pdf</a> (the ``Fact Sheet'').
\8\ In the B500 Approval Order, references to the ``B500 Index''
were to the ``Bloomberg US Large Cap Price Return Index,'' as
described in the Methodology Guide. The Exchange notes that the
Bloomberg US Large Cap Total Return Index and Bloomberg US Large Cap
Net Return Index have different calculations than the Bloomberg US
Large Cap Price Return Index. For example, the Bloomberg US Large
Cap Total Return Index reflects reinvestment of gross dividends and
the Bloomberg US Large Cap Net Return Index reflects the
reinvestment of net of tax dividends. See Methodology Guide, supra
note 6, at pages 14-15.
\9\ See Methodology Guide, supra note 6. Each component security
of the B500 Index must be primarily listed on one of the following
U.S. securities exchanges: NYSE, NYSE American, NYSE ARCA, IEX,
NASDAQ CM, NASDAQ GS, NASDAQ GM and CBOE BZX. See id., at page 4.
\10\ See Methodology Guide, supra note 6, at pages 4-7.
\11\ As previously represented to the Commission, the Exchange
will not list for trading B500 Index options until (i) the self-
certification filing by MIAX Futures is past the CFTC's statutory
review period; and (ii) MIAX Futures has commenced the listing and
trading of B500 Index futures. See Letter from Joseph W. Ferraro
III, SVP and Deputy General Counsel, the Exchange, to Vanessa
Countryman, Commission, dated April 2, 2025, available at <a href="https://www.sec.gov/comments/sr-miax-2025-08/srmiax202508-586555-1695102.pdf">https://www.sec.gov/comments/sr-miax-2025-08/srmiax202508-586555-1695102.pdf</a>. At the time of this filing, MIAX Futures has not yet
listed B500 Index futures.
---------------------------------------------------------------------------
As announced, BISL plans to rebrand the Bloomberg US Large Cap
Price Return Index as the Bloomberg 500 Index.\12\ For the avoidance of
doubt and to keep the name succinct for references across various sites
and collateral, BISL removed ``Price Return'' from the name of the B500
Index. However, references to the ``Total Return'' and ``Net Return''
derivations of the B500 Index, will be to the ``Bloomberg 500 Total
Return Index'' or the ``Bloomberg 500 Net Return Index,'' as the case
may be. Accordingly, the Exchange proposes to amend the table of
indexes in Exchange Rule 1801, Interpretation and Policy .01, to amend
the name of the B500 Index from the ``Bloomberg US Large Cap Price
Return Index'' to ``Bloomberg 500 Index'' under the heading
``Underlying Index''. The purpose of the proposed rule change is to
reflect the rebranded name of the B500 Index on which the Exchange is
authorized to list and trade options. This is to promote transparency
in its rules and eliminate any potential confusion among market
participants.
---------------------------------------------------------------------------
\12\ See supra note 4.
---------------------------------------------------------------------------
2. Statutory Basis
The Exchange believes the proposed rule change is consistent with
the Act and the rules and regulations thereunder applicable to the
Exchange and, in particular, the requirements of Section 6(b) of the
Act.\13\ Specifically, the Exchange believes the proposed rule change
is consistent with the Section 6(b)(5) \14\ requirements that the rules
of an exchange be 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 regulating,
clearing, settling, processing information with respect to, and
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.
---------------------------------------------------------------------------
\13\ 15 U.S.C. 78f(b).
\14\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------
The Exchange believes that the proposed rule change removes
impediments to and perfects the mechanism of a free and open market a
national market system, and protects investors and the public interest
by updating the Exchange's rules listing reporting authorities for
certain indexes to reflect the rebranded name of the B500 Index on
which the Exchange is authorized to list and trade options. The
Exchange believes this promotes transparency in its rules and may
eliminate any potential confusion
[[Page 38521]]
among market participants. The proposed rule change will have no impact
on the dissemination of index values of the B500 Index once listed on
the Exchange, but merely reflects the rebranded name of the B500 Index
on which the Exchange is authorized to list options. The Exchange
believes this proposal perfects the mechanism of a free and open market
a national market system, and protects investors and the public
interest because, with the proposed rebrand from the ``Bloomberg US
Large Cap Price Return Index'' to ``Bloomberg 500 Index,'' there will
be no change to the initial or maintenance listing criteria, expiration
months, settlement or exercise style of options on the B500 Index. The
Exchange notes that this proposal is simply to clarify the rebranded
name of the B500 Index. Values for the B500 Index will continue to be
disseminated and available to market participants in the same manner
and in the same intervals.\15\ The Exchange notes that it has not
listed options on the B500 Index at this time for business reasons.
---------------------------------------------------------------------------
\15\ On April 16, 2025, Miami International Holdings, Inc., the
parent company of the Exchange, announced that B500 Index values
began to be disseminated over the Options Price Reporting Authority
data feed and the MIAX Product Feed. See Press Release, Miami
International Holdings Begins Publishing Bloomberg 500 Index on OPRA
and MIAX Data Feeds, dated April 16, 2025, available at <a href="https://www.miaxglobal.com/sites/default/files/alert-files/MIAX_Press_Release_B500_Dissemination_4.16.25_Final.pdf">https://www.miaxglobal.com/sites/default/files/alert-files/MIAX_Press_Release_B500_Dissemination_4.16.25_Final.pdf</a>.
---------------------------------------------------------------------------
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.
Intramarket Competition
The Exchange believes the proposed rule change does not impose any
burden on intramarket competition that is not necessary or appropriate
in furtherance of the purposes of the Act. The proposed rule change is
not intended to address competitive issues but rather is concerned
solely with updating the name of the B500 Index. The proposed rule
change has no impact on the dissemination of index values for the B500
Index. Further, the Exchange has not yet listed options for trading on
the B500 Index.
Intermarket Competition
The Exchange believes the proposed rule change does not impose any
burden on intermarket competition that is not necessary or appropriate
in furtherance of the purposes of the Act. The proposed rule change is
not intended to address competitive issues but rather is concerned
solely with updating the name of the B500 Index. The proposed rule
change has no impact on the dissemination of index values for the B500
Index. Further, the Exchange has not yet listed options for trading on
the B500 Index.
C. Self-Regulatory Organization's Statement on Comments on the Proposed
Rule Change Received From Members, Participants, or Others
Written comments were neither solicited nor 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) of the Act \16\ and Rule 19b-
4(f)(6) \17\ thereunder.
