What is Relative Strength?

Relative Strength (RS) compares a stock's price performance to a benchmark (typically Nifty 50 or sector index) over a given period. A stock with rising RS is outperforming the market — these "relative strength leaders" tend to continue outperforming and are preferred by momentum investors.

Relative Strength — Indian Stock Market Example

During the 2022–2023 bull run, PSU banks showed strong relative strength vs Nifty 50 — identifying them as sector leaders early. IT stocks showed weakening RS in 2022 as global tech sold off. Screening for stocks with rising RS over 3–6 months is a core part of CAN SLIM and momentum-based strategies used by Indian investors.

Frequently Asked Questions about Relative Strength

How is Relative Strength different from RSI?

RSI (Relative Strength Index) measures internal momentum based on a stock's own price history. Relative Strength (RS) compares the stock's performance against an external benchmark (like Nifty 50). They measure different things: RSI = internal momentum; RS = comparative outperformance.

How do I calculate relative strength?

RS Line = Stock Price ÷ Benchmark Index Level, plotted over time. A rising RS line means the stock is outperforming the benchmark. Many platforms allow RS line overlay on charts. Alternatively, RS Ratio = (Stock return / Benchmark return) over a chosen period (e.g., 52 weeks).
