So, you woke up, grabbed your coffee, and checked your portfolio only to see the numbers frozen in time. It’s frustrating. You want to trade, but the ticker isn't moving. Honestly, the first thing everyone asks is whether the US market closed today or if their app is just glitching out again.
Usually, it's a holiday. Today, January 18, 2026, is a Sunday.

The New York Stock Exchange (NYSE) and the Nasdaq don't run on weekends. That’s the simple reality of it. While the world of 24/7 crypto has spoiled us into thinking markets should never sleep, the traditional financial world still loves its Saturdays and Sundays off. But there’s a lot more to market closures than just the weekend. Sometimes, the "why" behind a closed market is more interesting than the "when," especially when you factor in federal holidays or those rare, weird emergency shutdowns that catch everyone off guard.
The 2026 Trading Calendar: When the US Market is Closed
If you're looking at your screen on a weekday and wondering why things aren't moving, you’re likely hitting a federal holiday. For 2026, the schedule is pretty standard, but there are always little quirks. Tomorrow, Monday, January 19, the US market closed today logic actually extends into the next day because of Martin Luther King Jr. Day.
Everything stops.
No trading on the floor. No electronic execution for standard equities.
People forget that the market follows the federal government’s lead. If the post office is shut, there’s a high chance the NYSE is too. You’ve got the heavy hitters like Washington’s Birthday (February 16), Good Friday (April 3), and Memorial Day (May 25). Then there's Juneteenth, which is still a relatively new addition to the trading calendar but is now firmly established as a day when the lights go out at 11 Wall Street.
One thing that trips people up is "early closing." On days like the Friday after Thanksgiving or Christmas Eve, the market doesn't just stay open until 4:00 PM ET. It bails at 1:00 PM. If you’re trying to squeeze in a trade at 2:00 PM on those days, you’re out of luck. It’s basically a half-day for the finance world.
Why Do We Even Close the Markets?
It feels archaic, doesn't it? In an era where algorithms do most of the heavy lifting, why do we need to stop?
Tradition matters. But it's also about liquidity.
When the major banks and institutional players take a day off, the volume of shares being traded drops off a cliff. If the markets stayed open while the "big money" was at the beach, prices would be incredibly volatile. A small sell order could send a stock spiraling because there aren't enough buyers on the other side to catch it. Closing the market ensures that when we do trade, there’s enough "meat" in the market to keep prices stable and fair for everyone involved.
Beyond Holidays: When Things Go Wrong
Sometimes the US market closed today for reasons that aren't on any calendar. We call these "extraordinary closures."
Think back to the big ones. 9/11 shut the markets down for a week. Hurricane Sandy turned off the lights for two days in 2012. These aren't planned. They are moments of crisis where the physical or technical infrastructure of the financial system just can't handle the load. In 2026, we worry less about physical floods and more about digital ones. A massive cyberattack or a catastrophic failure in the data centers that house the exchange servers could trigger a "circuit breaker" on a national scale.
The Role of Circuit Breakers
Even when the market is "open," it can be temporarily closed.
Have you ever seen a stock price suddenly stop moving during a massive crash? That’s a Level 1 or Level 2 circuit breaker. If the S&P 500 drops by 7% before 3:25 PM, trading pauses for 15 minutes. It’s a "time-out" for grown-ups. It gives traders a second to breathe, look at the data, and stop panic-selling. If it hits 13%, we pause again. If it hits 20%? Pack it up. The market is done for the day.
Basically, the system is designed to break itself before it explodes.
What Happens to Your Money While the Market Is Shut?
Nothing. And everything.
Your shares don't disappear. They just sit there. But the value of those shares is constantly changing in the "shadows." While the NYSE is closed, news is still happening. A CEO might get fired. A war might break out. A new tech breakthrough might be announced.
This creates what we call "gap risk."
If the US market closed today at $100 and something huge happens overnight, it might "gap up" to $110 or "gap down" to $90 the moment it reopens. You can't do anything about it in the middle of the night. You’re just a passenger until the opening bell rings at 9:30 AM ET. This is why many professional traders hedge their positions before a long holiday weekend. They don't want to be caught off guard by three days of news they can't react to.
After-Hours and Pre-Market Trading
Now, just because the floor is closed doesn't mean all trading stops. You've probably heard of "after-hours" trading.
Most retail brokers like Charles Schwab, Fidelity, or Robinhood allow you to trade from 4:00 PM to 8:00 PM ET. There’s also pre-market trading starting as early as 4:00 AM ET. But be careful. It’s like the Wild West. The spreads—the difference between the buying price and the selling price—are much wider. You might end up paying a lot more for a stock than you would during normal hours.
If the market is closed for a holiday, however, these electronic sessions are usually closed too. You’re truly stuck waiting.
Looking at Global Markets
If the US market closed today, does that mean the whole world stopped?
Nope.

The London Stock Exchange (LSE), the Tokyo Stock Exchange (TSE), and the Hong Kong markets all have their own holiday schedules. Sometimes, US traders will look at how the Nikkei or the FTSE is performing to guess how the US markets will open. If the US is closed for Thanksgiving but London is trading, you might see American ADRs (American Depositary Receipts) moving on foreign exchanges. It’s a bit like looking through a window into a room you can’t enter yet.
What You Should Actually Do Today
Since you can't trade, use this time to actually think. Most people lose money because they trade on impulse. When the market is closed, the adrenaline dies down.
- Review your stop-losses. Since you can't change them right now, write down the prices where you’d actually want to exit a position.
- Read the boring stuff. Go to the SEC’s EDGAR database. Look up the 10-K or 10-Q filings for the companies you own. Most people never read these, which is wild because that’s where the real skeletons are buried.
- Check the macro environment. Look at what the Federal Reserve is saying. In 2026, interest rate whispers still drive the market more than actual earnings do.
- Organize your watch list. Sort your stocks by "conviction." If the market opened tomorrow and everything was down 5%, what would you actually want to buy?
The market being closed is a gift of perspective. It forces you to stop staring at the 1-minute candles and start looking at the 1-year chart. The most successful investors aren't the ones clicking "buy" every ten seconds; they’re the ones who know exactly what they’re going to do before the market even opens.
Tomorrow is Martin Luther King Jr. Day. The banks are closed. The post office is closed. And yes, the stock market is closed. Take the day off. The tickers will be there on Tuesday morning, spinning just as fast as they always do.
