Trading Hours and Pre/After Market
US markets offer extended trading hours beyond the regular session.
- Regular hours: 9:30 AM – 4:00 PM Eastern Time (ET)
- Pre-market: 4:00 AM – 9:30 AM ET (lower volume, wider spreads)
- After-hours: 4:00 PM – 8:00 PM ET (earnings announcements often move stocks here)
- India time equivalents: Market opens at 7:00 PM IST (10:00 PM IST in winter)
- Extended hours trading is riskier due to lower liquidity and larger bid-ask spreads
