The stock market opens at 9:30 a.m. Eastern Time on weekdays

The New York Stock Exchange (NYSE) and NASDAQ — the two largest U.S. stock exchanges — both begin regular trading at 9:30 a.m. ET. This is when the opening bell rings and most individual investors can buy and sell stocks. The market stays open until 4:00 p.m. ET, giving traders a standard six-and-a-half-hour window each business day.

If you live outside the Eastern Time zone, you need to convert. 9:30 a.m. ET is 8:30 a.m. Central, 7:30 a.m. Mountain, and 6:30 a.m. Pacific. Many brokerages send notifications when the market opens, which can help if you are planning to trade at the start of the day.

Key Takeaways

  • Regular stock market hours run from 9:30 a.m. to 4:00 p.m. Eastern Time, Monday through Friday.
  • The market is closed on weekends and on federal holidays, even if you can still see prices on your brokerage app.
  • Pre-market trading begins as early as 4:00 a.m. ET, but most individual investors cannot participate and prices can be thin and volatile.
  • After-hours trading runs from 4:00 p.m. to 8:00 p.m. ET, though again most retail investors have limited access and wider bid-ask spreads.
  • Your brokerage may have its own rules about when you can place orders, so check your account settings if you plan to trade outside regular hours.

Pre-market trading starts before 9:30 a.m.

Trading does happen before the official 9:30 a.m. open, but it is not the same as regular market hours. Pre-market trading typically runs from 4:00 a.m. to 9:30 a.m. ET, though the exact window depends on your broker. During this time, institutional investors and some retail traders can place orders, but volume is much lower and prices can swing sharply on small trades.

Most individual investors cannot trade during pre-market hours, or their broker charges a fee or requires special permission. Even if you can access it, the bid-ask spread — the gap between what buyers will pay and what sellers will accept — is often much wider than during regular hours. A stock might show one price in pre-market and a very different price at 9:30 a.m. when the main market opens.

After-hours trading runs until 8:00 p.m. ET

After the 4:00 p.m. close, trading continues in what is called the after-hours session, which typically runs until 8:00 p.m. ET. Like pre-market trading, after-hours volume is lower, spreads are wider, and prices can be more volatile. News released after 4:00 p.m. — such as earnings reports or major announcements — often moves stock prices in after-hours trading before the next regular market open.

Your broker may or may not let you trade after hours. Some charge fees, some require a minimum account balance, and some restrict which stocks you can trade. If you place an order after 4:00 p.m., it may not execute until the next regular market open, depending on your broker's rules and the type of order you place.

The market is closed on weekends and federal holidays

The stock market does not open on Saturdays or Sundays. It also closes on federal holidays, including 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, you cannot trade stocks, though you can still view prices and place orders that will execute when the market reopens.

Some brokerages show a holiday calendar in your account settings so you know in advance when the market will be closed. If you are planning a trade around a holiday, remember that the market will be closed the day before or after, which can affect how quickly your order fills.

Time zones matter if you trade at market open or close

The 9:30 a.m. ET open is the official start time, but if you live on the West Coast, that is 6:30 a.m. your time. Many traders on the Pacific coast set alarms or use their broker's notification system to catch the open. The last hour of trading — 3:00 p.m. to 4:00 p.m. ET — is often the most active, and that is 12:00 p.m. to 1:00 p.m. Pacific.

If you trade on a schedule, write down the ET times and convert them once, then set reminders. Brokerages display times in your local zone in your account, but the market itself always operates on Eastern Time, so knowing the ET window prevents confusion.

Your broker may have different rules for order placement

Even though the market opens at 9:30 a.m. ET, your specific brokerage may not let you place orders at that exact moment. Some brokers have a brief delay, some require you to log in and confirm you are ready to trade, and some have their own internal rules about when orders can be submitted. A few brokers also restrict certain order types — like stop-loss orders — until a few minutes after the open.

Check your broker's help section or call their customer service to understand their specific rules. If you plan to trade at market open or close, test placing an order during those times before you need to do it for real. This way you will know whether there are any delays or restrictions that affect your strategy.

Frequently Asked Questions

Can I trade stocks before 9:30 a.m.?

Yes, if your broker offers pre-market trading, which usually starts at 4:00 a.m. ET. However, most retail investors cannot access it, or their broker charges a fee. Even if you can trade, prices are less stable and spreads are wider than during regular hours.

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

It depends on your broker and the type of order. Some orders execute in after-hours trading if you have that access. Others wait until 9:30 a.m. the next trading day. Check your broker's documentation or call them to confirm how they handle after-hours orders.

Is the market open on holidays?

No. The market is closed on weekends and federal holidays like Thanksgiving, Christmas, and Independence Day. You can view prices and place orders that will execute when the market reopens, but no trading happens on those days.

Does the market close early on any days?

Yes. On the day before Thanksgiving and the day before Christmas, the market closes at 1:00 p.m. ET instead of 4:00 p.m. Check your broker's holiday calendar to confirm early closes for the year.

What if I forget what time the market opens?

Set a recurring alarm or calendar reminder for 9:30 a.m. ET. Most brokerages also send notifications when the market opens if you turn on alerts in your account settings. Your broker's website or app usually displays a countdown to market open as well.
