Market Breadth for NSE Stocks: Advance-Decline, % Above MAs & ARMS
Advance-decline ratios, percent of stocks above moving averages, and the ARMS index — how market breadth tells you if NSE participation is healthy or fragile.
Why Market Breadth Matters for NSE Traders
A rising Nifty 50 can hide a weak market. When only a handful of heavyweights drive the index, most NSE stocks may be flat or falling — a narrow rally that often reverses. Market breadth measures how many stocks participate in a move, giving you a health check before you commit capital.
Our Market Breadth dashboard tracks advance-decline ratios, the percentage of stocks above key moving averages (50-day and 200-day), and new highs vs new lows across 1,800+ NSE equities. Use it daily alongside your stock screener to avoid buying into fragile rallies.
Key Breadth Indicators Explained
Advance-Decline (A/D) line: when more stocks rise than fall consistently, the rally has broad participation. Percent above 50-day MA above 60% suggests a healthy uptrend; below 40% warns of deterioration even if the index is green. Percent above 200-day MA shows long-term trend strength — above 50% is bullish for swing and position traders.
The ARMS index (also called TRIN) compares advancing vs declining volume to advancing vs declining issues. Values below 1.0 suggest buying pressure; above 1.0 suggests selling pressure. Our ARMS dashboard breaks this down by Nifty 500, Nifty Midcap, and sector groups so you can spot where money is flowing.
How to Combine Breadth with Screening
When breadth is strong (broad A/D, high % above MAs), lean into momentum and breakout screeners — the odds of follow-through are higher. When breadth weakens while the index holds up, tighten filters, reduce position size, or shift to quality and reversal setups.
