1 articles · Updated · Yahoo Finance · Jul 30

Summary

  • Sept. 17 is when the SEC will hold a public roundtable on whether U.S. stock markets can operate 23 hours a day, five days a week.
  • Paul Atkins said the agency is studying infrastructure, liquidity, risk and investor protections, with one daily hour reserved to shut systems down for software updates.
  • Major U.S. exchanges are preparing to be ready by year-end, even though centralized exchange trading still does not run around the clock.
  • 24-hour access already exists at brokers including Robinhood, Interactive Brokers and Charles Schwab for select stocks, underscoring pressure on regulators to adapt to global off-hours trading.
