When the overall market falls, most stocks fall with it. A few do not. They dip less, recover faster or simply move sideways while everything around them weakens. That behaviour is called relative strength, and it is one of the most useful clues a momentum trader has.

Why it matters
Relative strength shows where demand is. If buyers keep supporting a stock while the index slides, they are telling you they want to own it even in a poor environment. When the market pressure lifts, those same stocks often have the least overhead supply and the most eager buyers, so they tend to lead the next move.
How to see it without special tools
- Compare the lows. During a market pullback, note whether the stock made a lower low or held above its prior low while the index broke down.
- Use a ratio line. Most charting platforms let you plot the stock divided by an index. A rising line means the stock is outperforming.
- Check new highs first. Stocks that reach new highs before the index does are showing leadership early.
What it is not
Relative strength is not a buy signal by itself. A strong stock can still be extended, sitting far above any sensible stop. The aim is to build a short watchlist of leaders, then wait for each one to offer a clean setup with a clear stop.
Track relative strength every week and your watchlist will start to fill with the stocks the market itself is choosing.
