Market Hours and After-Hours Trading
Stock markets have regular trading sessions, with some brokers also offering pre-market and after-hours trading.
The simple explanation
Stock markets have regular trading sessions, with some brokers also offering pre-market and after-hours trading.
Why it matters
Liquidity and spreads can change sharply outside normal hours.
A simple way to think about it
Lower participation can mean wider spreads, thinner order books and larger reactions to news. Order type matters more when liquidity is reduced.
A common beginner mistake
Expecting an after-hours price to behave like a price during the busiest part of the session.
What to check next
- Check that you understand the definition in plain English.
- Look at the company, market and timeframe rather than one number alone.
- Ask what could change the interpretation.
- Keep risk separate from excitement or certainty.
One calm takeaway
Stock markets have regular trading sessions, with some brokers also offering pre-market and after-hours trading. Use it as one piece of context, never as a promise about what happens next.
