# After-Hours Trading

*Trading & Technical Analysis — Finicade finance glossary*

After-hours and pre-market sessions let trading continue outside normal exchange hours, which is when most earnings and major news are released. Liquidity is a fraction of the regular session, so spreads are wide and prices move violently on small volume. An extended-hours price is a poor guide to where a stock will actually open, and market orders in these sessions are genuinely dangerous.

**Also known as:** extended hours, pre-market trading, post-market
