The stock market closes at 4 p.m. Eastern Time on regular trading days

The New York Stock Exchange (NYSE) and NASDAQ — the two largest U.S. stock markets — both stop accepting trades at 4 p.m. ET every weekday. This is called the closing bell. If you place an order after 4 p.m., it will not execute until the next trading day opens at 9:30 a.m. ET.

The exact time in your zone depends on where you live. If you are on Pacific Time, that is 1 p.m. If you are on Central Time, that is 3 p.m. If you are on Mountain Time, that is 2 p.m. The market does not adjust for daylight saving time — it stays on Eastern Time year-round, so your local conversion changes twice a year.

After 4 p.m., trading continues on after-hours markets, but volume is much lower, spreads are wider, and prices can swing sharply on thin trading. Most individual investors do not trade after-hours because the risk is higher and the liquidity is worse.

Key Takeaways

  • Regular market hours are 9:30 a.m. to 4 p.m. Eastern Time, Monday through Friday.
  • Orders placed after 4 p.m. ET will not fill until the next trading day opens at 9:30 a.m. ET.
  • The market is closed on weekends and on 11 federal holidays each year, including Thanksgiving and Christmas.
  • After-hours trading exists from 4 p.m. to 8 p.m. ET, but it carries higher risk and lower liquidity than regular hours.

Market holidays when the market does not open at all

The NYSE and NASDAQ close completely on certain days. These are not just weekends — they include federal holidays and a few market-specific closures. The market does not open 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 some holidays, the market opens for a shortened session. The day after Thanksgiving and Christmas Eve (when it falls on a weekday) are half-days, closing at 1 p.m. ET instead of 4 p.m. ET. Check your broker's holiday calendar before the holiday week to confirm whether the market will be open and for how long.

Why the market closes at 4 p.m. and not another time

The 4 p.m. close is a historical convention. When the NYSE was founded in 1792, trading happened in person on the street, and 4 p.m. was when traders stopped for the day. The time has stuck through two centuries of technology changes — from floor traders to telephone to electronic systems — because it is now baked into the entire financial infrastructure. Brokers, clearing houses, and regulators all expect it.

The 9:30 a.m. open was set in 1985 to give traders on the West Coast time to arrive at their desks before trading began. Before that, the market opened at 10 a.m. ET. The times are not arbitrary, but they are not immovable either — the SEC could change them, but doing so would disrupt every market participant and every algorithm built around the current schedule.

What happens in the last minutes before 4 p.m.

The final moments of the trading day are often the most volatile. Traders rush to close positions before the close, and some funds rebalance their portfolios at the end of the day. This can cause sharp price swings in the last 10 to 15 minutes. Some brokers let you set orders to execute only during the last minute, or only at the close itself, to take advantage of this.

The closing auction is a formal process that happens in the final seconds. Brokers submit orders to buy and sell, and the exchange matches them all at a single price — the official closing price for the day. This price is what you see reported on the news and what your portfolio statement uses to calculate your daily gain or loss.

After-hours trading and when it ends

After the 4 p.m. close, most brokers offer after-hours trading from 4 p.m. to 8 p.m. ET. This is not an official market — it is a network of electronic communication networks (ECNs) where traders can still buy and sell. Volume is a fraction of regular hours, so prices can move sharply on small trades, and you may not be able to buy or sell at the price you see quoted.

Not all stocks trade after-hours, and not all brokers offer after-hours access. Check your broker's rules before you try to place an order after 4 p.m. Some brokers charge extra for after-hours trading, and some restrict which stocks you can trade. If you place an after-hours order and it does not fill by 8 p.m., it will cancel and not carry over to the next day — you have to resubmit it during regular hours.

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

Before the official 9:30 a.m. open, some brokers let you trade during pre-market hours, usually from 4 a.m. to 9:30 a.m. ET. This is also conducted on ECNs, not the official exchange, so the same risks apply: low volume, wide spreads, and sharp price swings. News released before the market opens — earnings reports, economic data, geopolitical events — can cause big moves in pre-market trading.

Pre-market prices are not the official opening price. When the regular market opens at 9:30 a.m., the opening auction happens, and the official open can be very different from where the stock traded in pre-market. If you hold a pre-market position overnight, it will carry into the regular session, but if you sell in pre-market, you will not be able to buy back until regular hours begin.

Frequently Asked Questions

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

The market closes at 1 p.m. ET on the day before Thanksgiving (the Wednesday before the fourth Thursday in November). This is a half-day session. The market is completely closed on Thanksgiving itself.

Can I place an order at 3:59 p.m. and have it fill after 4 p.m.?

No. Any order placed before 4 p.m. ET will attempt to fill during regular hours. If it does not fill by 4 p.m., it will cancel at the close unless you set it to carry over to after-hours or the next day. Check your broker's default settings for how orders are handled at the close.

Does the stock market close earlier on Fridays?

No. The market closes at 4 p.m. ET every weekday, including Friday. The only days the market closes early are the day after Thanksgiving and Christmas Eve (when it falls on a weekday), both at 1 p.m. ET.

What if I forget to sell before 4 p.m. and the market is closed tomorrow?

Your position will hold overnight and into the next trading day. When the market reopens, you can place a sell order during regular hours. If the market is closed the next day (a holiday or weekend), your position will hold until the market reopens, and prices may move significantly in the meantime.

Can I set an order to sell exactly at 4 p.m.?

You can set an order to execute at the close, which means it will participate in the closing auction in the final seconds before 4 p.m. The exact price you receive depends on the auction results, not on a price you set in advance. Ask your broker whether they support "close" orders or "market on close" orders.
