SEC: extended-hours trading is under 1% of volume, EDGAR overnight in question

  • Extended hours account for less than 1% of NMS stock volume and are concentrated in a few securities
  • NSCC has operated 24x5 since June: from Sunday 20:00 to Friday 20:00
  • The new data processing schedule takes effect December 6, with market-wide limits approved
  • EDGAR processes filings after 17:30 only on the next business day
Why it matters: Round-the-clock stock trading is part of the trend toward tokenization and 24/7 markets; overnight disclosure delays could become a risk for investors.
