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 the official market open, when the opening bell rings and buy and sell orders start executing at published prices. The market stays open for six and a half hours, closing at 4:00 p.m. ET.

This timing applies Monday through Friday, excluding federal holidays when the exchanges shut down entirely. The schedule does not change for daylight saving time — the exchanges adjust their operations, but the 9:30 a.m. ET start time remains constant year-round.

If you live outside the Eastern Time zone, you need to convert. 9:30 a.m. ET is 8:30 a.m. Central Time, 7:30 a.m. Mountain Time, and 6:30 a.m. Pacific Time. International traders convert to their own time zones from ET.

Key Takeaways

  • Regular stock market trading runs from 9:30 a.m. to 4:00 p.m. Eastern Time on weekdays only.
  • The NYSE and NASDAQ both follow this same schedule; no major U.S. exchange opens earlier or later during regular hours.
  • Pre-market trading begins as early as 4:00 a.m. ET, but prices are less stable and spreads are wider than during regular hours.
  • After-hours trading runs from 4:00 p.m. to 8:00 p.m. ET, and volume is much lower than during the regular session.
  • The market is closed on weekends and federal holidays, with no trading at any time on those days.

Pre-market trading starts before the official open

Trading does not begin exactly at 9:30 a.m. — it begins before that. Pre-market trading starts at 4:00 a.m. ET on most brokerages, though some firms open their systems earlier or later. During pre-market hours, you can place orders and trades execute, but the volume is much lower and price swings can be sharp.

Pre-market prices are not the same as the official opening price. When 9:30 a.m. arrives and the regular session begins, a new price is set based on all the orders that have accumulated — both from pre-market and from the moment the bell rings. This opening price can be significantly different from the last pre-market trade.

Most individual investors do not trade pre-market because the spreads (the gap between buy and sell prices) are wider, meaning you pay more to buy and receive less when you sell. Institutional traders and market makers are the primary participants before 9:30 a.m.

After-hours trading continues after the close

After-hours trading runs from 4:00 p.m. to 8:00 p.m. ET, giving traders a window to buy and sell after the regular session ends. Like pre-market trading, after-hours volume is lower and spreads are wider. Price movements can be volatile because fewer traders are active.

News released after 4:00 p.m. — such as earnings announcements or major company events — can move a stock significantly during after-hours trading. The price you see at 5:00 p.m. may be very different from the 4:00 p.m. close, but when the market opens the next morning at 9:30 a.m., the opening price is set fresh based on all accumulated orders.

Not all brokerages offer after-hours trading to individual investors, and not all stocks can be traded after hours. Check with your broker to see whether after-hours trading is available on your account.

Federal holidays close the market entirely

The stock market does not open on federal holidays, even if the day falls on a weekday. The NYSE and NASDAQ publish a holiday calendar each year listing the days when both exchanges will be closed. Common closure dates include New Year's Day, Independence Day, Thanksgiving, and Christmas.

On holiday closures, there is no pre-market trading, no regular session, and no after-hours trading. The market is completely shut down. If you have standing orders (such as limit orders or stop orders) placed before the holiday, they remain in effect and may execute when the market reopens the next trading day.

Some holidays result in an early close rather than a full closure. The day after Thanksgiving and the day before Christmas, for example, see the market close at 1:00 p.m. ET instead of 4:00 p.m. ET. The opening time remains 9:30 a.m. ET on these days.

International stock exchanges have different hours

If you trade stocks on exchanges outside the United States, the opening times are different. The London Stock Exchange opens at 8:00 a.m. GMT. The Tokyo Stock Exchange opens at 9:00 a.m. JST. The Frankfurt Stock Exchange opens at 8:00 a.m. CET. Each exchange operates on its own local time and its own holiday calendar.

When converting international market hours to your time zone, account for the time difference and daylight saving time changes, which do not occur on the same dates worldwide. A market that opens at 8:00 a.m. in London opens at 3:00 a.m. ET during Eastern Standard Time but 2:00 a.m. ET during Eastern Daylight Time.

Most U.S. brokerages do not offer direct access to international exchanges during their local hours. Instead, you typically trade international stocks through ADRs (American Depositary Receipts) during U.S. market hours, or you use a broker that specializes in international trading.

How to know if the market is open right now

The simplest way to check whether the market is currently open is to look at a major financial website. Bloomberg, Yahoo Finance, MarketWatch, and the official NYSE and NASDAQ websites all display a banner or indicator showing whether the market is in regular session, pre-market, after-hours, or closed.

Your brokerage account also shows the market status. When you log in, you will see whether you can place orders that execute when ready (regular hours) or whether orders will be queued for the next session (outside regular hours). Some brokerages display a clock showing time until the market opens or closes.

If you are unsure whether a specific day is a trading day, check the NYSE holiday calendar on the official exchange website. It lists every closure and early close for the current and upcoming years.

Frequently Asked Questions

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

Yes, through pre-market trading starting at 4:00 a.m. ET on most brokerages. However, prices are less stable, spreads are wider, and volume is much lower than during regular hours. Not all stocks can be traded pre-market, and not all brokerages offer it to individual investors.

What happens to my order if I place it after 4:00 p.m.?

If you place an order after 4:00 p.m. ET on a weekday, it enters after-hours trading if your broker supports it. Otherwise, it queues and executes when the market opens the next morning at 9:30 a.m. ET. The price you receive may be very different from the after-hours price you saw.

Does the market open earlier on any day?

No. The regular market session always opens at 9:30 a.m. ET on weekdays. Pre-market trading begins earlier (as early as 4:00 a.m. ET), but that is not the official market open. The official open is always 9:30 a.m. ET.

What time does the market close on the day before Thanksgiving?

The market closes at 1:00 p.m. ET on the day after Thanksgiving (the Friday following the holiday). It opens at the regular 9:30 a.m. ET time. The day before Thanksgiving operates on a normal schedule with a 4:00 p.m. close.

Can I trade on weekends?

No. The stock market is completely closed on weekends. There is no pre-market, regular, or after-hours trading on Saturday or Sunday. Trading resumes Monday morning at 4:00 a.m. ET (pre-market) and 9:30 a.m. ET (regular session).
