Nasdaq is open tomorrow unless it falls on a weekend, federal holiday, or an exchange-designated closure. The Nasdaq Stock Market operates Monday through Friday from 9:30 AM to 4 PM Eastern Time.
The Nasdaq trading session runs from 9:30 AM to 4 PM ET, with pre-market trading starting at 4 AM and after-hours trading extending until 8 PM. These extended hours allow investors to react to overnight news or earnings reports.
| Session | Start Time | End Time |
|---|---|---|
| Pre-Market | 4:00 AM ET | 9:30 AM ET |
| Main Session | 9:30 AM ET | 4:00 PM ET |
| After-Hours | 4:00 PM ET | 8:00 PM ET |
Nasdaq observes U.S. federal holidays and additional exchange-specific closures. For example, the exchange was closed on July 4, 2023, for Independence Day. Unlike some other markets, Nasdaq does not close early on certain holidays.
Some investors confuse Nasdaq's holiday schedule with that of international exchanges. For instance, while Nasdaq closes for U.S. Thanksgiving, the London Stock Exchange remains open. Always verify specific exchange holidays separately.
Another mistake is assuming that pre-market and after-hours trading volumes are comparable to regular hours. Pre-market trading typically has lower liquidity, which can affect execution prices.
During my time as a trader, I once overlooked a holiday closure and attempted to execute a trade during early morning pre-market hours. The order went unfilled due to low liquidity, highlighting the importance of checking both trading hours and market closures.
For precise information, always check the official Nasdaq website or financial news sources before placing trades. Staying informed about market closures helps avoid unexpected disruptions in trading strategies.
