How NSE selects stocks for Nifty 50
The National Stock Exchange reviews the composition of the Nifty 50 twice a year — in March and September — using the average free-float market capitalisation over the preceding six months. Free-float market cap measures the market value of shares available for trading by the public, excluding promoters’ and locked-in holdings.
Why this matters for investors
Adjustments to the Nifty 50 often lead to sharp price and volume swings as passive funds tracking the index buy and sell to match the new weights. Market participants watch the rejig closely to identify short-term trading opportunities and liquidity shifts in the underlying stocks.
