GLOSSARY // Day Trading

Momentum Trading

Momentum trading buys strength and sells weakness — the bet that a stock already moving on volume will keep moving in the same direction, the direct opposite of mean-reversion strategies that fade extremes. Intraday, it means concentrating on the handful of stocks each day with a catalyst, outsized relative volume, and range.

Edge comes from selection and exits, not prediction. Momentum traders do not forecast which stock will run; they wait for one that already is, join it at a defined level (a breakout, a dip to VWAP, a red-to-green cross), and cut instantly when the move stalls. The style front-loads losses — many small stop-outs — against occasional multi-point winners, so it lives or dies on keeping the average loss a fraction of the average gain.

worked example

Out of 6,000 listed stocks, a scanner surfaces the one trading 25x normal volume, up 30% on an FDA catalyst. A momentum trader takes three entries during the day: a $9.40 opening range break stopped out for -$0.20, a $9.60 VWAP dip buy sold at $10.40, and a $10.55 high-of-day break sold at $11.30. Two winners at +$0.80 and +$0.75 against one -$0.20 loss.
