Stock Market Glossary
Day trader
Trader who holds positions exclusively within one trading day.
In brief: Trader who holds positions exclusively within one trading day.
Meaning in practice
Day traders avoid overnight risks, but are heavily dependent on the spread, order type and ability to react. Studies show that the majority lose money in the long term – few disciplined professionals make it permanently.
Context for investors and traders
For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.
How to use this in practice
Use the term first to describe the situation and add verifiable data: time frame, benchmark, costs and liquidity. Only then does it become an assessment that can be connected to an investment objective and risk budget.
What to keep in mind
Avoid false precision. Many market terms describe probabilities or historical patterns; they neither guarantee a return nor replace the review of a specific security.
