Relative Strength (RS)
Also called: RS line, RS rating
How a stock is performing versus a benchmark like the S&P 500 — leaders outperform the index, laggards trail it.
Relative strength (not to be confused with RSI) compares a stock's return to the market's. A rising RS line means the stock is outpacing the index — the hallmark of leadership that momentum and growth traders hunt for.
The IBD-style RS Rating ranks each stock's price performance against the whole universe on a 1–99 percentile scale, so a 90 means the stock outperformed 90% of all stocks.
