NYSE American Files Immediate Rule Change to Expand Trading Halt Requirements
The amendment to Rule 7.18E, filed Aug. 11, 2026, binds NYSE American-listed securities subject to corporate actions, effective immediately.
On Aug. 21, 2026, the Securities and Exchange Commission published a notice that NYSE American LLC filed a proposed rule change on Aug. 11, 2026. The filing appears under Release No. 34-106175, File No. SR-NYSEAMER-2026-73 and FR Doc No. 2026-17363 in Vol. 91, No. 164, pp. 55132-55138. The proposal seeks immediate effectiveness under Section 19(b)(1) of the Securities Exchange Act of 1934 and Rule 19b-4.
The amendment would revise Rule 7.18E to establish specific requirements for halting and resuming trading in securities that are subject to certain corporate actions. The Exchange cites the upcoming "23/5 Trading" model - trading 23 hours a day, five days a week - as a driver for the change, noting that the reduced non-trading window could increase operational risk for corporate-action processing.
NYSE American's proposal mirrors a recent amendment approved for NYSE Arca, which was noticed for immediate effectiveness on July 8, 2026 (Securities Exchange Release No. 105862, 91 FR 42999). That earlier change extended the mandatory regulatory halt framework that the Exchange first implemented for reverse stock splits in a March 27, 2024 filing (SR-NYSEAMER-2024-22).
Under the new rule, when a listed security is affected by any of the enumerated corporate actions, the Exchange would impose a mandatory regulatory halt before the start of overnight trading on other markets at 9:00 p.m. ET. Trading would then resume with a Trading Halt Auction at 8:00 a.m. ET, replacing the current 9:00 a.m. ET auction time for reverse-split halts.
The Commission is soliciting comments from interested persons. The full text of the proposed amendment and related statements are available on the Exchange's website at www.nyse.com and at the Exchange's principal office.
