In remarks at a SIFMA roundtable, the U.S. Securities and Exchange Commission’s Division of Trading and Markets Director Jamie Selway voiced support for industry efforts to expand U.S. equity trading hours toward 24-by-7 trading, while stressing that common protocols, shared infrastructure and key operational issues such as corporate actions must be addressed before a broad market shift. Equity market infrastructure has long supported trading from 4 a.m. to 8 p.m. ET, and several platforms have recently launched overnight trading, including four alternative trading systems. Selway pointed to Commission actions approving 24X’s Form 1 application, which included an overnight session, and NYSE Arca’s proposal to extend trading hours, while Nasdaq’s similar proposal remains out for public comment. He also cited industry planning for supporting infrastructure, including a proposal by the equity market data plans to extend Securities Information Processor operating hours by the end of 2026 and an expectation that the National Securities Clearing Corporation will be ready in June 2026, alongside interest from some participants in more timely Trade Reporting Facility reporting during extended hours.
