What is RS (Relative Strength)? Meaning and Importance in India

Relative Strength (RS) compares a stock's performance against a benchmark, usually by dividing the stock's price by the index value. A rising RS line means the stock is outperforming the index, whether markets are rising or falling. It is distinct from RSI, which measures a stock against its own history.

Suppose over one month NIFTY rises about 12% while LTIMindtree rises about 38%. Rebase both to 100 at the start and the stock's line pulls clearly above the index, so its RS line keeps climbing. That steady outperformance is the footprint institutions leave when they are accumulating a leader.

Why does relative strength matter so much?

Market leaders reveal themselves through RS before they reveal themselves through absolute price: stocks that resist corrections tend to lead the next rally. Institutions rotate capital toward relative winners, making the RS line a proxy for that flow. A stock hitting new RS highs before new price highs is one of the oldest institutional accumulation tells.

How do traders use RS in stock selection?

The classic filter is trading long only in stocks with rising RS versus NIFTY, concentrating capital where the market is already voting. Sector RS adds a layer: strong stocks within strong sectors compound the tailwind. RS divergence warns too: a stock making price highs while its RS line flattens is losing leadership even as it looks healthy.
