The Nifty Bank Index is computed using the free-float market capitalisation method, based on its 12 constituent banking stocks. Free float refers to the shares available for public trading, excluding promoter and strategic holdings. The index is calculated using the formula:

Index Value = (Current Index Free Float Market Capitalisation / Base Free Float Market Capitalisation) × Base Index Value

In this calculation, Index Free Float Market Capitalisation equals the number of current outstanding shares multiplied by the Investible Weight Factor (IWF), capping factor, and market price. The Nifty Bank undergoes a semi-annual review using data as of January 31 and July 31. Any stock changes are implemented on the last trading day of March and September.
