Pre-market trading occurs before regular market hours, typically from 4:00 AM to 9:30 AM ET. This session allows traders to react to overnight news, earnings releases, and global market events before the regular session opens. Pre-market trading is characterized by lower liquidity, wider spreads, and higher volatility compared to regular market hours.
