The U.S. Securities and Exchange Commission has published the agenda and panel lineup for its previously announced September 17 roundtable on preparations for 24-hour trading. The discussion will assess market readiness, operational resilience and the expected effects of expanding trading hours, while identifying remaining work before near-continuous trading begins. The first panel will cover exchange and broker-dealer readiness, overnight surveillance, closing-price processes, clearance and settlement changes, investor protection and expected liquidity. A second panel will examine systems and market-data continuity, Regulation Systems Compliance and Integrity considerations, capacity, cybersecurity, shortened maintenance windows and overnight staffing. The final session will consider effects on liquidity, capital formation, issuers and market participation, as well as potential regulatory and infrastructure steps for any future move toward 24/7 trading. The public roundtable will run from 10 a.m. to 4 p.m. Eastern time at the SEC’s Washington headquarters and will be webcast live, with a recording available later.
