Pre-Market Trading Hours
4:00 AM – 9:30 AM Eastern Time, Monday–Friday
What is Pre-Market Trading?
Pre-market trading is an extended session that occurs before the regular NYSE and NASDAQ session opens at 9:30 AM ET. It runs from 4:00 AM to 9:30 AM Eastern Time, Monday through Friday, excluding US market holidays.
During pre-market hours, traders react to overnight news, earnings releases, and economic data before the broader market opens. Volume is typically much lower than regular trading hours, which leads to wider bid-ask spreads and higher price volatility.

Key Events During Pre-Market
Earnings from S&P 500 companies typically arrive between 8:00 and 9:30 AM ET, making that window the most active part of the session. Scheduled economic data — CPI prints, jobs reports, Fed statements — usually drops at 8:30 AM ET. Large overnight moves in ES and NQ futures often telegraph pre-market direction before individual stocks start trading; European market sentiment, set hours earlier, also carries over into this session.
Pre-Market Risks
Bid-ask spreads before the open are routinely 2–10× wider than during regular hours, because far fewer participants are active. That thin liquidity means a modest order can shift prices noticeably. The price a stock trades at 9:29 AM may look nothing like where it opens at 9:30 AM when the full order book arrives. Most brokers also restrict you to limit orders only, so you can't chase a move with a market order.
FAQ
What time does pre-market trading open?
Pre-market opens at 4:00 AM Eastern Time, Monday through Friday, and runs until the regular session begins at 9:30 AM ET. The live countdown above shows the exact time remaining in your timezone.
Is pre-market open on holidays?
No. Pre-market follows the same calendar as the regular session — closed on all 10 federal holidays. On early close days, pre-market still opens at 4:00 AM ET but the regular session ends at 1:00 PM ET instead of 4:00 PM. See the full holiday schedule.
What happens when the regular session opens at 9:30 AM?
At 9:30 AM ET, accumulated pre-market orders hit the order book simultaneously. Volume surges, spreads tighten, and price discovery accelerates. The 9:30–10:00 AM window is typically the highest-volume 30-minute period of the trading day.
Can I trade all stocks in pre-market?
Most exchange-listed equities are available, but liquidity varies sharply. Large-cap S&P 500 names typically have active pre-market markets. Smaller stocks may have no bids at all. Options do not trade until the regular session opens at 9:30 AM ET.
