U.S. SEC Commissioner Poses "Six Questions" on U.S. Stock 23*5 Trading: Calls for Attention to Liquidity, Information Disclosure, and Other Issues

SEC Commissioner Hester M. Peirce noted that extended trading hours for U.S. equities are increasingly taking shape around a "23-hours-a-day, five-days-a-week" framework. While overnight trading currently represents less than 1% of total NMS stock volume and remains highly concentrated in a select few equities, both established and emerging trading venues have been actively extending their operating hours over the past two years. In light of this trend, she outlined six key questions: 1. How should the U.S. equity market leverage the experiences of well-established foreign exchange, cryptocurrency, and futures markets? 2. How should broker-dealers fulfill their best execution obligations and enhance retail investor protection amid fragmented overnight liquidity and widening spreads? 3. Is it still a prudent fiduciary decision for asset managers to opt out of overnight trading when liquidity is scarce and execution costs are elevated? 4. Will extended trading hours alter the manner in which public companies issue earnings releases and material disclosures? 5. Given that EDGAR submissions filed after 5:30 p.m. ET are generally processed on the next business day, should the SEC modify the EDGAR system to facilitate timely disclosure of material information during overnight trading sessions? 6. Should the SEC issue relevant guidance or grant regulatory relief to public companies, particularly smaller companies?
