U.S. pre-market trading runs from 4:00 a.m. to 9:30 a.m. Eastern Time on Nasdaq and NYSE Arca, and from 7:00 a.m. on the NYSE’s other markets. Regular trading runs from 9:30 a.m. to 4:00 p.m. ET, Monday to Friday, and after-hours trading runs from 4:00 p.m. to 8:00 p.m. ET. Your broker decides which part of those windows you can actually use.
Key takeaways
- Nasdaq’s pre-market session runs from 4:00 a.m. to 9:30 a.m. ET, and its after-hours session runs from 4:00 p.m. to 8:00 p.m. ET.
- On the NYSE, NYSE American, NYSE Chicago and NYSE National, early trading starts at 7:00 a.m. ET after a 7:00 a.m. opening auction.
- Brokers set their own extended-hours windows and usually accept limit orders only, so the hours you can trade may be shorter than the exchange’s.

Why the pre-market matters
The pre-market is where news released overnight or before the open gets its first price. Earnings reported after the previous close, company announcements and economic data released at 8:30 a.m. ET all show up here first. That is why stocks often “gap” up or down at 9:30 a.m.: the price has already moved in early trading.
Index futures trade almost around the clock and are the main gauge of how the whole market is likely to open. Our guide to how stock futures work explains how to read them.
Can you trade in the pre-market?
Usually yes, but on your broker’s terms, not the exchange’s. Brokers choose their own extended-hours window and rules. Fidelity, for example, accepts pre-market orders from 7:00 a.m. to 9:28 a.m. ET, limit orders only. Check your broker’s extended-hours page before placing an order.
The risks of trading before the bell
- Thin volume. Fewer shares change hands, so a single large order can move the price.
- Wide spreads. The gap between the bid and ask is often larger than during the regular session, which raises your cost.
- Volatility. Prices react to headlines in seconds and can reverse when the regular session opens.
- Prices may not carry over. A pre-market move is not a promise of where a stock will trade after 9:30 a.m.
Holidays and early closes
U.S. stock exchanges close on most federal holidays and close early, at 1:00 p.m. ET, on certain days. In 2026 the early closes fall on the day after Thanksgiving and on Christmas Eve. Extended-hours sessions follow the same holiday calendar. See the full list of stock market holidays for 2026–2028.

Frequently asked questions
What time does pre-market trading start?
At 4:00 a.m. ET on Nasdaq and NYSE Arca, and at 7:00 a.m. ET on the NYSE and its other markets. Most brokers open their pre-market window later than 4:00 a.m.
What time does the stock market open?
The regular U.S. session opens at 9:30 a.m. ET and closes at 4:00 p.m. ET, Monday to Friday.
Is pre-market trading a good guide to the open?
Partly. Large pre-market moves on real news often hold, but low volume means prices can reverse once the regular session brings in full liquidity.
What time is it in other time zones?
The 9:30 a.m. ET open is 2:30 p.m. in London and 10:30 p.m. in Singapore while the U.S. is on standard time (early November to mid-March). When the U.S. is on daylight time, it is 9:30 p.m. in Singapore.
