The US Securities and Exchange Commission is bringing Wall Street market participants together this month to discuss the industry’s preparations for 24-hour stock trading, as US exchanges move toward extending trading beyond traditional market hours.
The agency said Tuesday that its Sept. 17 roundtable will examine operational readiness, market resilience and the broader effects of near-continuous trading.
The opening panel will assess whether exchanges and broker-dealers are ready for extended hours, with discussions covering overnight surveillance, pricing and settlement processes, investor safeguards and liquidity. Robinhood, NYSE, BlackRock, Virtu, Cboe, BNY Pershing, UBS and FINRA are among the firms represented.
The second session will turn to the infrastructure needed to keep markets operating reliably overnight. Topics will include cybersecurity, market-data continuity, system capacity, failover procedures, Regulation SCI requirements and staffing, with participants from Nasdaq, DTCC, Jane Street, State Street, Schwab, Interactive Brokers and other firms.
The closing panel will examine how longer trading hours could affect liquidity, capital formation and market participation, while considering future market-structure changes and a potential expansion toward 24/7 trading.
