The advance-decline ratio divides rising stocks by falling ones. A 2:1 day means twice as many winners - healthy participation. A rising index with a sub-1 ratio means a few giants mask broad weakness.
Professionals distrust rallies the ratio doesn't confirm: narrow leadership breaks first when sentiment turns.
Example
Nifty up 0.5% while the advance-decline reads 1:2 warns the headline is HDFC Bank and Reliance carrying 1,800 fallers - fragile, not strong.
In Ticker Screener
True whole-market breadth sits above gainers and losers: Nifty 500 totals for India, NYSE + Nasdaq for the USA - not partial counts.
