Remember when the stock market used to have business hours? Like a bank or a Blockbuster Video? Well, Nasdaq just decided that’s so 2015. The exchange is officially asking the SEC for permission to go full 24/5—that’s 24 hours a day, five days a week, Monday through Friday. No more closing bell at 4 p.m. ET. No more waiting until tomorrow to panic-sell your positions.
Nasdaq President Tal Cohen dropped this bombshell in a blog post, and honestly, it’s kind of genius if you think about it. The company plans to file the paperwork with the SEC soon, with a target launch date of late 2026. So we’re talking about a pretty serious timeline here.
Why Now? Global Money Never Sleeps
Here’s the thing: the world doesn’t stop trading when Wall Street closes. Foreign investors have been absolutely crushing it in U.S. markets—foreign holdings of American equities have nearly doubled since 2019, hitting $17 trillion as of mid-2024. That’s a lot of people in Tokyo, London, and Singapore who’d love to trade during their actual business hours instead of at 2 a.m.
Cohen points out that 56 new ETFs tracking the Nasdaq 100 have launched in the last five years, and get this—98% of them were created outside the U.S. International investors are basically saying, “We want in, but can you make it convenient?” Fair point.
The Catch? It’s Complicated
Of course, nothing’s ever simple in finance. Lower liquidity during overnight hours means higher volatility and potentially gnarlier transaction costs. Imagine trying to sell 10,000 shares at 3 a.m. ET when there’s basically nobody else awake to buy them. Yikes.
There’s also the corporate issuer problem. Nasdaq surveyed its listed companies, and about half of them are nervous about 24-hour trading. They’re worried about liquidity, corporate actions, and all the operational headaches that come with round-the-clock markets. Fair concern.
Then there’s the tech side. U.S. markets process millions of messages per second. Adding 24-hour trading means upgrading infrastructure, coordinating across the entire industry, and making sure nothing breaks. It’s like trying to add a second kitchen to a restaurant while it’s still serving dinner.
The NYSE Already Started This
Nasdaq isn’t alone in this ambition. The New York Stock Exchange filed with the SEC last fall to expand NYSE Arca (the ETF powerhouse) to 22-hour trading, running from 1:30 a.m. to 11:30 p.m. ET. So the dominoes are already falling.
The Bottom Line
Is 24-hour trading coming? Probably. Will it be chaos at first? Absolutely. But Cohen’s right about one thing: the question isn’t whether we can build a 24/5 market—it’s how we do it without breaking everything. For global investors tired of setting alarms at weird hours, this could be a game-changer. For retail traders? Well, let’s just say you might want to set some stop-losses before you go to bed.
