When the Stock Market Closes and Why the Time Matters
The stock market closes at 4 p.m. Eastern Time on regular trading days
The closing time for the main U.S. stock exchanges — the New York Stock Exchange (NYSE) and the NASDAQ — is 4 p.m. Eastern Time, Monday through Friday. This is the moment when the regular trading session ends and the official closing price for each stock is set. If you are on the West Coast, that is 1 p.m. Pacific Time. If you are in the Central or Mountain time zones, adjust accordingly.
The market does not close at the same time every day in the sense that the closing time itself never changes, but the market is closed on weekends and on certain federal holidays. On those days, there is no closing time because there is no trading session at all. The market also closes early — at 1 p.m. Eastern Time — on the day before Thanksgiving and on Christmas Eve, when those days fall on a weekday.
Key Takeaways
- Regular market hours end at 4 p.m. Eastern Time, and this closing price becomes the official price for that day's trades.
- The market is closed on weekends and federal holidays, so there is no closing time on those days.
- You can trade stocks before the market opens (starting at 4 a.m. Eastern) and after it closes (until 8 p.m. Eastern) through extended-hours trading, though with fewer buyers and sellers.
- If you place an order after 4 p.m., it will not execute until the next trading day unless you specifically request after-hours trading.
- Stock prices you see on financial websites update in real time during market hours but may be delayed by 15 to 20 minutes after the market closes.
Why the 4 p.m. closing time matters for your trades
The closing price at 4 p.m. is the official price used to settle trades and calculate your portfolio value at the end of the day. If you place a market order — an order to buy or sell immediately at the current price — and you place it before 4 p.m., it will execute during regular hours. If you place it after 4 p.m., it will wait until the market opens the next morning at 9:30 a.m. Eastern Time and execute then, possibly at a different price.
This matters because stock prices can move significantly overnight, especially if news breaks after the market closes. If you see a stock price you like at 3:59 p.m. and place an order at 4:05 p.m., you are not may provide to get that price. The stock could open the next morning much higher or much lower depending on what happened after hours.
Extended-hours trading before and after the regular session
You can trade stocks outside the regular 9:30 a.m. to 4 p.m. window through extended-hours trading, also called pre-market and after-hours trading. Pre-market trading typically runs from 4 a.m. to 9:30 a.m. Eastern Time. After-hours trading typically runs from 4 p.m. to 8 p.m. Eastern Time. Not all brokers offer both, and not all stocks trade during these windows.
Extended-hours trading has real drawbacks. There are fewer buyers and sellers, so the bid-ask spread — the difference between what someone will pay and what someone will sell for — is wider. This means you may get a worse price than you would during regular hours. Some stocks barely trade at all during extended hours. If you place an order during extended hours and it does not fill, it will not automatically carry over to the regular session unless you specifically set it to do so.
What happens to your orders placed after the market closes
If you place a market order after 4 p.m. on a regular trading day, your broker will hold it and send it to the market when the next session opens at 9:30 a.m. the following day. The order will execute at whatever price the stock is trading at that moment, which could be very different from the price you saw when you placed the order.
If you want more control, you can place a limit order instead, which tells your broker to buy or sell only at a specific price or better. A limit order placed after hours will wait until the market opens and will execute only if the stock reaches your price. If the stock never reaches that price, the order may not fill at all. Limit orders are safer than market orders when you are trading outside regular hours, but they also carry the risk that you will miss the trade entirely.
How to know if the market is open today
The market is closed on Saturdays and Sundays and on these federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. When one of these holidays falls on a Saturday, the market is usually closed on the Friday before. When it falls on a Sunday, the market is usually closed on the Monday after.
The market also closes early at 1 p.m. Eastern Time on the day before Thanksgiving and on Christmas Eve, if those days are weekdays. On all other weekdays, the market opens at 9:30 a.m. and closes at 4 p.m. Eastern Time. If you are unsure whether the market is open on a specific day, the NYSE and NASDAQ websites both publish their holiday calendars.
Why closing time is set at 4 p.m. Eastern
The 4 p.m. closing time is a historical convention that has stuck because it works for the financial system. The New York Stock Exchange has been in New York for over 200 years, and 4 p.m. Eastern Time was chosen to allow traders on the East Coast to conduct business and still have time to settle trades and communicate with markets in Europe before the European close. The time also gives the clearing houses — the organizations that settle trades behind the scenes — enough time to process the day's transactions before the next day begins.
Changing the closing time would require coordination across the entire financial system, including brokers, exchanges, clearing houses, and regulators. The cost and complexity of such a change means the 4 p.m. time is unlikely to shift, even though markets around the world operate on different schedules.
Frequently Asked Questions
Can I trade stocks at 3:30 p.m. or 3:45 p.m.?
Yes. Any time before 4 p.m. Eastern Time on a regular trading day is during market hours, and your order will execute during the regular session. Orders placed at 3:30 p.m. or 3:45 p.m. will fill at the market price at that moment, just like any other time during the trading day.
What if I place an order at 4:01 p.m.?
If you place a market order at 4:01 p.m., it will not execute until the market opens the next morning at 9:30 a.m. Eastern Time. The stock price could be significantly different by then. If you want to trade after hours, ask your broker whether they offer after-hours trading and whether your stock trades during that window.
Does the market close at different times on different days?
The regular closing time is always 4 p.m. Eastern Time, Monday through Friday, except for the day before Thanksgiving and Christmas Eve, when it closes at 1 p.m. Eastern Time. The market does not open at all on weekends and federal holidays, so there is no closing time on those days.
Why do stock prices change after 4 p.m. if the market is closed?
Stock prices you see after 4 p.m. are from after-hours trading, where a smaller number of traders are buying and selling. These prices are real trades, but they happen outside the main market session. Most individual investors do not trade during these hours, so the prices may not reflect what the stock will open at the next morning.
If I see a stock price at 3:59 p.m., am I may provide to get that price if I buy?
No. The price you see is the last trade that occurred, but by the time your order reaches the market, the price may have changed. During the final seconds before 4 p.m., prices can move quickly. If you place a market order, you will get whatever price the stock is at when your order executes, which may be higher or lower than what you saw.
