Relative strength scanner for NSE stocks
Relative strength (RS) answers one question: is this stock rising faster than the rest of the market? Market Strength Scanner ranks every stock in its India (NSE) universe by RS, so leaders and laggards are visible at a glance.

Relative strength compares a stock’s price performance with its market over the same period. A stock that gains 20% while its index gains 10% has outperformed, even though both rose. Traders who follow momentum look for stocks that keep outperforming because leadership tends to persist for months, not days.
The scanner turns this into an RS rating from 1 to 99: the stock’s percentile rank among all stocks scanned. A rating of 90 means the stock’s weighted return beat about 90% of the universe.
How the RS rating is built
The rating blends returns over several look-back windows (roughly 3, 6, 9 and 12 months, with the most recent quarter weighted most) and ranks the result across the whole universe. Using several windows rewards stocks that are strong both recently and over the longer run, and avoids one lucky month dominating the score.
Because it is a percentile, the rating adapts to the market: in a weak market a stock only needs to fall less than its peers to rank high.
Ways to use an RS scan
- Leaders: stocks with RS above 80 that are also near their 52-week high and above a rising 200-day average.
- RS line new highs: the stock-to-index ratio makes a 52-week high, often before the price itself breaks out.
- RS improvers: the biggest one-month gains in rating, showing new strength.
- Strong in a weak market: stocks still rising while the index falls.
- Sector leaders: the highest-RS stocks inside the strongest sectors.
Liquidity and quality filters
A high RS rating on an illiquid stock is hard to act on. The scanner lets you restrict results to liquid stocks (minimum traded value) and market-cap bands, so rankings are usable for real position sizes.
Frequently asked questions
What is a good RS rating?
There is no single threshold, but many momentum traders focus on ratings above 70 to 80, because market leaders usually come from the top of the ranking. The rating is a ranking tool, not a prediction.
Is relative strength the same as RSI?
No. RSI (relative strength index) is an oscillator built from one stock’s own recent gains and losses. Relative strength compares a stock with other stocks or with an index.
Which markets are covered?
Indian NSE-listed stocks, ranked against the Indian market.
Does a high RS rating mean I should buy?
No. It shows what has been strong, nothing more. Use it to build a shortlist, then do your own analysis and risk management.
