SEC Roundtable to Evaluate 24-Hour U.S. Equity Trading Proposal
Public company counsel, exchange operators, and investor-facing financial firms must monitor the SEC’s upcoming 24-hour equity trading roundtable to prepare for operational and disclosure compliance shifts.
The U.S. Securities and Exchange Commission is convening a roundtable to discuss transitioning domestic equity markets to 24-hour trading, with Nasdaq’s proposed 23-hour, 5-day-a-week system potentially launching as early as December pending final SEC approval. The shift would introduce new operational risks for exchanges, public companies, and investors, though existing exchange governance frameworks and SEC oversight are expected to mitigate many concerns. Stakeholders should also anticipate potential requirements to expand EDGAR filing system access to align with extended market hours, and prepare for adjustments to disclosure timelines and trading operation protocols ahead of any formal rule adoption.
