When the Stock Market Opens and Closes: Trading Hours You Need to Know

Regular trading hours for U.S. stock exchanges

The U.S. stock market opens at 9:30 a.m. Eastern Time and closes at 4:00 p.m. Eastern Time, Monday through Friday. These times apply to the major exchanges where individual stocks trade: the New York Stock Exchange (NYSE) and the NASDAQ. If you place an order during these hours, it executes during the regular session.

The market does not open on weekends or on federal holidays. When a holiday falls on a weekday, the exchanges close for the entire day — there is no trading at all. The market also closes early at 1:00 p.m. Eastern Time on the day after Thanksgiving and on Christmas Eve, if either falls on a weekday.

Time zones matter. If you live on the West Coast, 9:30 a.m. Eastern is 6:30 a.m. Pacific. If you live in Central Time, it is 8:30 a.m. Central. Most brokers display times in your local zone, but the market itself runs on Eastern Time, so it is worth knowing the conversion if you trade actively.

Key Takeaways

• Regular trading runs from 9:30 a.m. to 4:00 p.m. Eastern Time on weekdays only, and the market is closed on weekends and federal holidays.
• Extended hours trading — before 9:30 a.m. and after 4:00 p.m. — is available through most brokers but has lower volume and wider price spreads.
• Pre-market trading starts as early as 4:00 a.m. Eastern, and after-hours trading runs until 8:00 p.m. Eastern on most brokers.
• Orders placed outside regular hours may not fill at the price you see, because fewer traders are active and prices can move more sharply.
• ETFs and mutual funds trade during regular market hours, but mutual fund orders placed after 4:00 p.m. execute at the next day's closing price.

Pre-market trading before the official open

Many brokers let you trade before 9:30 a.m. Eastern in what is called the pre-market session. The earliest you can usually start is 4:00 a.m. Eastern, though some brokers open at 7:00 a.m. or 8:00 a.m. instead. Check your broker's rules, because not all brokers offer pre-market trading, and those that do may charge a fee or require a minimum account balance.

Pre-market trading is thinner than regular trading. Fewer traders are active, so the bid-ask spread — the gap between the price someone will pay and the price someone will sell at — is wider. A stock might trade at $50.00 during the day but show a spread of $49.80 to $50.30 in pre-market hours. You may also see larger price swings on smaller volume, which means a single large order can move the price more than it would during the regular session.

News often breaks before the market opens. Company earnings reports, economic data, and other announcements frequently come out before 9:30 a.m., and pre-market trading lets you react immediately. However, the risk is that you are trading on incomplete information and with less certainty about where the price will settle once regular trading begins.

After-hours trading after the close

After the market closes at 4:00 p.m. Eastern, most brokers offer after-hours trading until 8:00 p.m. Eastern. Like pre-market trading, after-hours sessions have lower volume and wider spreads. A stock that closed at $50.00 might trade at $49.70 to $50.40 in after-hours, and the price can move sharply on a single order.

After-hours trading is useful when news breaks after the close. Earnings reports often come out at 4:30 p.m. or later, and after-hours trading lets you position yourself before the next day's open. However, the same risks apply: fewer traders mean less certainty about execution price, and the price you see after hours may not hold when regular trading resumes.

Not all stocks trade actively in after-hours sessions. Large, widely held stocks like Apple or Microsoft have decent after-hours volume. Smaller or less popular stocks may have almost no after-hours trading, which means your order might not fill at all, or might fill at a price far from what you expected.

How extended hours affect mutual funds and ETFs

ETFs trade like stocks, so they follow the same hours: 9:30 a.m. to 4:00 p.m. Eastern during regular trading, with pre-market and after-hours sessions available through your broker. The same spread and volume concerns apply.

Mutual funds work differently. You cannot trade mutual funds during extended hours. If you place an order to buy or sell a mutual fund at any time during the day — whether at 10:00 a.m. or 3:59 p.m. — it executes at the fund's closing price, which is calculated once per day after the market closes at 4:00 p.m. Eastern. This is called the Net Asset Value (NAV). You do not know the exact price until after 4:00 p.m., but you do know it will be the same price everyone else who traded that day received.

This is one key difference between ETFs and mutual funds. ETFs let you trade throughout the day at changing prices, like stocks. Mutual funds execute once daily at a fixed price set after the close.

What happens on market holidays

The stock market closes completely on the following federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving, and Christmas. On these days, there is no regular trading, no pre-market session, and no after-hours session.

The day after Thanksgiving and Christmas Eve (if it falls on a weekday) are half days. The market opens at 9:30 a.m. but closes at 1:00 p.m. Eastern. Pre-market trading runs normally, but there is no after-hours session.

If you have a standing order set to trade on a holiday, most brokers will hold it and execute it on the next trading day instead. Check your broker's policy if you are unsure, because some brokers cancel orders that cannot fill on the day you placed them.

Time zone conversion and planning your trades

The market runs on Eastern Time regardless of where you live. If you are on the West Coast, the open at 9:30 a.m. Eastern is 6:30 a.m. Pacific, and the close at 4:00 p.m. Eastern is 1:00 p.m. Pacific. Central Time is one hour ahead of Pacific, so the open is 8:30 a.m. Central and the close is 3:00 p.m. Central. Mountain Time is 7:30 a.m. to 2:00 p.m.

Most brokers show times in your local time zone automatically, but if you read market news or listen to financial commentary, times are usually given in Eastern. Knowing the conversion helps you plan when to place orders and when to expect market-moving announcements.

If you trade pre-market or after-hours, the time zone difference matters even more. Pre-market starts at 4:00 a.m. Eastern, which is 1:00 a.m. Pacific — very early if you are on the West Coast. After-hours runs until 8:00 p.m. Eastern, which is 5:00 p.m. Pacific, so West Coast traders have a more reasonable window for after-hours activity.

Why market hours matter for your investment strategy

If you buy and hold stocks or ETFs for years, market hours barely matter. You place an order during the regular session, it fills, and you move on. Extended hours trading is not relevant to your strategy.

If you trade more actively or respond to news, hours matter more. Earnings announcements, economic reports, and company news often come out before the open or after the close. Knowing when you can trade and understanding the risks of extended-hours sessions helps you decide whether to act immediately or wait for regular trading to resume.

The wider spreads and lower volume in pre-market and after-hours sessions mean you pay more to buy and receive less when you sell. For a large order, this cost can be significant. For a small order, it may not matter. Understanding your broker's hours and the conditions in each session lets you choose the timing that fits your situation.

Frequently Asked Questions

Can I trade stocks at 8:00 a.m. Eastern?

It depends on your broker. Most brokers offer pre-market trading starting at 4:00 a.m., 7:00 a.m., or 8:00 a.m. Eastern. Check your broker's website or app to see when pre-market trading opens for your account. Not all brokers offer it, and some charge a fee or require a minimum balance.

What happens if I place an order after 4:00 p.m.?

For stocks and ETFs, the order goes into the after-hours session if your broker offers it, and it may fill between 4:00 p.m. and 8:00 p.m. Eastern. For mutual funds, the order executes at the next day's closing price, regardless of when you place it. Ask your broker which applies to your account.

Why is the spread wider in pre-market and after-hours trading?

Fewer traders are active outside regular hours, so there are fewer buyers and sellers. Market makers — traders who profit by buying and selling — charge a wider spread to compensate for the risk of holding a stock when volume is low and prices can move sharply.

Does the market ever open early or close late?

No. Regular trading always runs from 9:30 a.m. to 4:00 p.m. Eastern on weekdays, except for the half days (1:00 p.m. close) on the day after Thanksgiving and Christmas Eve. The market does not extend regular hours for any reason.

What time should I place my order to get the best price?

During regular trading hours (9:30 a.m. to 4:00 p.m. Eastern), spreads are tightest and volume is highest, so execution is most predictable. If you are not responding to breaking news, placing your order during regular hours usually gives you the best price and the most certainty that your order will fill.
