NYSE proposes immediate amendment to Rule 7.18 to expand trading halt requirements
The amendment, filed Sep 1 2026 and effective immediately, would apply to NYSE-listed securities undergoing specified corporate actions under the upcoming 23/5 trading schedule.
On September 1, 2026, New York Stock Exchange LLC filed with the Securities and Exchange Commission a proposed amendment to Rule 7.18 ("Trading Halts"). The filing, identified as Release No. 34-106356; File No. SR-NYSE-2026-41 and published in the Federal Register (FR Doc No. 2026-19131) on September 15, 2026, is effective upon filing.
The Exchange proposes to set forth specific requirements for halting and resuming trading in securities that are subject to certain corporate actions. The proposal builds on the framework previously adopted for reverse stock splits and is intended to provide greater transparency and clarity for securities undergoing issuer-related events, particularly as the market moves toward a 23-hours-a-day, 5-days-a-week trading schedule.
Under the proposal, a mandatory regulatory halt would be imposed on an affected security before the start of overnight trading on other venues at 9:00 p.m. Eastern Time. Trading would then resume with a Trading Halt Auction after 9:30 a.m. Eastern Time, at the start of the Exchange's Core Trading Session. Notification of the halt and its termination would be provided in accordance with Rule 7.18.
The Commission is publishing this notice to solicit comments from interested persons. The Exchange notes that NYSE Arca filed a substantially identical amendment on July 8, 2026, which the Commission also noticed for immediate effectiveness.
The Exchange expects other primary listing markets to adopt substantially identical versions of the rule to ensure consistent treatment of corporate actions across the market.
