Post-market trading occurs after regular market hours, typically from 4:00 PM to 8:00 PM ET. This session enables traders to react to earnings reports, late-breaking news, and corporate announcements. Like pre-market, it’s characterized by lower liquidity, wider spreads, and potentially higher volatility than regular trading hours.
