    On April 21, 2023, Miami International Securities Exchange LLC 
(``MIAX'' or ``Exchange'') filed with the Securities and Exchange 
Commission (the ``Commission''), pursuant to section 19(b)(1) of the 
Securities Exchange Act of 1934 (the ``Act''),\1\ and Rule 19b-4 
thereunder,\2\ a proposed rule change to amend Exchange Rule 307, 
Position Limits, to establish a process for adjusting option position 
limits following a stock split or reverse stock split in the underlying 
security. The proposed rule change was published for comment in the 
Federal Register on May 8, 2023.\3\ The Commission has received no 
comment letters regarding the proposed rule change.

---------------------------------------------------------------------------

    Section 19(b)(2) of the Act \4\ provides that within 45 days of the 
publication of notice of the filing of a proposed rule change, or 
within such longer period up to 90 days as the Commission may designate 
if it finds such longer period to be appropriate and publishes its 
reasons for so finding or as to which the self-regulatory organization 
consents, the Commission shall either approve the proposed rule change, 
disapprove the proposed rule change, or institute proceedings to 
determine whether the proposed rule change should be disapproved. The 
45th day after publication of the notice for this proposed rule change 
is June 22, 2023.

    \4\ 15 U.S.C. 78s(b)(2).
---------------------------------------------------------------------------

    The Commission is extending the 45-day time period for Commission 
action on the proposed rule change. The Commission finds that it is 
appropriate to designate a longer period within which to take action on 
the proposed rule change so that it has sufficient time to consider the 
proposed rule change. Accordingly, pursuant to section 19(b)(2) of the 
Act,\5\ the Commission designates August 6, 2023, as the date by which 
the Commission shall either approve or disapprove, or institute 
proceedings to determine whether to disapprove, the proposed rule 
change (File No. SR-MIAX-2023-19).
