What relative strength is
Relative strength compares one stock's trend to others'. (Don't confuse it with RSI, which measures a single stock's internal momentum.) The strongest names in a group are those holding the most constructive position relative to their trend.
How to read it
- Stocks furthest above their 200-day are showing the strongest long-term relative trend.
- Leadership tends to persist — strength begets strength — until it doesn't.
How we use it
On every sector page we rank constituents by distance to the 200-day, a clean proxy for relative trend strength, so the leaders rise to the top.
