When the Stock Market Opens and Closes: U.S. Trading Hours
Regular Trading Hours for U.S. Stock Markets
The stock market opens at 9:30 a.m. Eastern Time and closes at 4:00 p.m. Eastern Time, Monday through Friday. These are the hours when the major U.S. exchanges — the New York Stock Exchange (NYSE) and the NASDAQ — conduct their main trading sessions. 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 federal holiday falls on a weekday, the exchanges close entirely. If you try to place a trade outside regular hours, your order will not execute until the market reopens.
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. The opening bell rings at the same moment across the country, but your local clock will show a different time.
Key Takeaways
- Regular trading runs from 9:30 a.m. to 4:00 p.m. Eastern Time, Monday through Friday.
- The market is closed on weekends and federal holidays, and your orders will not execute outside regular hours.
- Pre-market trading begins as early as 4:00 a.m. Eastern, and after-hours trading runs until 8:00 p.m. Eastern, but with lower volume and wider price swings.
- Most individual investors trade during regular hours because prices are more stable and it is easier to buy or sell what you want at a predictable price.
Pre-Market Trading Before 9:30 a.m.
Some brokers let you trade before the official opening. Pre-market trading typically starts at 4:00 a.m. Eastern Time and runs until 9:30 a.m. Not all brokers offer this, and not all stocks can be traded during pre-market hours. You will need to check your broker's rules to see whether they support it and which stocks are available.
Pre-market trading is thinner than regular trading. Fewer buyers and sellers are active, so the price can jump more sharply on smaller trades. If you place a large order, you may not be able to fill it all at one price. Most individual investors avoid pre-market trading because the risk of a bad price is higher.
News often breaks before the market opens — earnings reports, economic data, or company announcements. Some traders use pre-market hours to position themselves before the regular session begins. If you do trade pre-market, understand that you are accepting wider price swings in exchange for an earlier entry point.
After-Hours Trading After 4:00 p.m.
After-hours trading runs from 4:00 p.m. to 8:00 p.m. Eastern Time. Like pre-market trading, it is available through most major brokers but not all stocks participate, and volume is much lower than during regular hours. The same risks apply: prices can move sharply, and you may not be able to buy or sell the exact quantity you want at a single price.
After-hours trading is most active right after the 4:00 p.m. close, when traders react to earnings announcements or other news released during the regular session. As the evening goes on, volume drops further. By 7:00 p.m., very few trades are happening.
If you hold a stock and major news breaks after 4:00 p.m., you can trade in after-hours, but the price may be very different from where it closed at 4:00 p.m. Many investors wait for the regular session to open the next morning rather than risk a bad price in thin after-hours trading.
Why Regular Hours Matter More Than Extended Hours
During regular trading hours, millions of shares change hands every minute. The sheer volume means prices are stable and competitive. If you want to buy 100 shares of a major stock, you will almost certainly get filled at or near the current price. Bid-ask spreads — the difference between what buyers offer and what sellers ask — are tight.
Outside regular hours, spreads widen. The difference between the best bid and the best ask can be several cents or more per share, which adds up on larger positions. For a stock trading at $50, a 10-cent spread in after-hours trading costs you real money. During regular hours, the spread might be a penny or two.
Most brokers also charge higher commissions or wider markups for pre-market and after-hours trades, though many have moved to commission-free trading. Even without explicit fees, the wider spreads mean you are paying more to trade outside regular hours.
Federal Holidays When the Market Closes
The stock market closes on 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, no trading happens at all, and your orders will not execute.
The day after Thanksgiving (the Friday after Thanksgiving) is a partial trading day. The market opens at 9:30 a.m. but closes at 1:00 p.m. Eastern Time instead of 4:00 p.m. Christmas Eve is also a partial day if it falls on a weekday, closing at 1:00 p.m.
If you place an order on a holiday or after hours, it will sit in your broker's system until the market reopens. Most brokers let you set the order to execute "at market open" the next trading day, which means it will fill as soon as the 9:30 a.m. bell rings. You can also set a limit price, which means your order will only execute if the stock hits that price or better.
How to Plan Your Trades Around Market Hours
If you work during regular trading hours and cannot watch the market, you have options. You can place orders before the market opens (they will execute at 9:30 a.m. or shortly after) or after it closes (they will execute the next day). You can also set limit orders that sit in the system until your price is hit, which may take days or weeks.
Many investors use limit orders specifically because they do not need to be watching when the trade happens. If you want to buy a stock at $50 but it is currently trading at $52, you can set a limit order to buy at $50. When the price drops to $50, your order fills automatically, even if you are not looking at your screen.
If you are a long-term investor buying stocks or funds to hold for years, the exact time of day you trade matters very little. The difference between buying at 9:30 a.m. and 3:00 p.m. on the same day is usually just a few cents. What matters more is that you are buying at a reasonable price and holding for the long term.
Time Zone Conversions for Different U.S. Regions
The market opens and closes at the same moment everywhere in the United States, but your local time is different depending on where you live. Here is what 9:30 a.m. and 4:00 p.m. Eastern Time translate to in other zones:
| Time Zone | Market Open | Market Close |
|---|---|---|
| Eastern | 9:30 a.m. | 4:00 p.m. |
| Central | 8:30 a.m. | 3:00 p.m. |
| Mountain | 7:30 a.m. | 2:00 p.m. |
| Pacific | 6:30 a.m. | 1:00 p.m. |
Daylight Saving Time does not change these relationships. When the entire country switches to or from daylight time, the market opening and closing times stay the same relative to Eastern Time, so the conversion above holds year-round.
Frequently Asked Questions
Can I place a trade at 8:00 p.m. and have it execute that night?
No. If you place a trade after 8:00 p.m. Eastern (or before 4:00 a.m. Eastern), it will not execute until the market reopens at 9:30 a.m. the next trading day. Some brokers offer after-hours trading until 8:00 p.m., but after that window closes, your order waits until morning.
What happens to my order if I place it right before the market closes?
If you place an order between 3:59 p.m. and 4:00 p.m. Eastern, it may or may not execute during the regular session depending on how close to 4:00 p.m. you placed it and how fast your broker processes it. If it does not fill by 4:00 p.m., it will carry over to the next trading day unless you cancel it. You can specify whether you want the order to stay active across multiple days or expire at the end of the day.
Do international stock markets have different hours?
Yes. The London Stock Exchange opens at 8:00 a.m. GMT and closes at 4:30 p.m. GMT. The Tokyo Stock Exchange opens at 9:00 a.m. JST and closes at 3:00 p.m. JST. If you want to trade stocks on other exchanges, you will need a broker that offers access to those markets and you will need to know their local trading hours.
Why does the market close at 4:00 p.m. instead of later in the evening?
The 4:00 p.m. close is a historical convention set when the NYSE was founded in 1792. It has remained the standard for over 200 years. Some exchanges around the world have different hours, but the U.S. market has kept this schedule because it is when the majority of trading volume happens and when most institutional traders wrap up their day.
If the market is closed on a holiday, can I still check stock prices?
Yes. Stock prices are public information and you can look them up anytime. What you cannot do is place a trade. Your broker's website and most financial news sites will show you the last price from the previous trading day, and some will show you pre-market prices the next morning before 9:30 a.m.
