Pre-market and after-hours: meaning, example and why it matters
Trading that happens outside a stock exchange's regular session. Volume is usually thinner, spreads wider and prices more jumpy than in regular hours.
Worked example
A stock quoted $100.00 bid and $100.50 ask in regular hours might show $99.50 and $101.00 after hours. The gap widens from 0.5% to about 1.5%.
Illustrative numbers for explanation only. They are not market data, a forecast or a suggestion.
Why it matters
Thinner trading means wider gaps and bigger jumps, so the same order can cost more outside regular hours.
