Nasdaq says it plans to file with the SEC to allow U.S. stocks and ETFs to trade almost around the clock, five days a week, starting as early as the second half of 2026. The proposal would stretch trading to 23 hours per weekday, splitting the market into a long “day session” (4 a.m.–8 p.m. ET), a one-hour pause, and an overnight session (9 p.m.–4 a.m.). Supporters argue this just formalizes what already exists in crypto and futures, and better serves global investors who don’t operate on U.S. time zones. Critics aren’t convinced. Concerns center on thinner liquidity during overnight hours, bigger price swings, and whether constant trading would amplify short-term speculation rather than improve price discovery. Curious how others see this. Is nearly nonstop equity trading the natural next step, or does it risk creating more volatility without real benefits for long-term investors?
