Definition of Nifty Bank Index

The Nifty Bank index is a sectoral benchmark on the National Stock Exchange (NSE) that tracks the performance of large and liquid banking stocks. It consists of up to 12 stocks, including public, private, and other banks. Launched on 15 September 2003, with a base year of 2000 and a base value of 1000, it is reconstituted semi-annually to reflect market changes. No stock exceeds 33%, and the top three cannot surpass 62% collectively. With a 17.6% CAGR (2000–2021), it has outperformed Nifty 50 in six of 10 years (2011–21). Governed by NSE Indices Limited, it also has a total returns variant for ETFs and funds.

Nifty Bank Index Value Calculation

The Nifty Bank index is calculated based on the free-float market capitalisation of its 12 constituent stocks. Free float represents shares available for public trading, excluding promoter holdings. The index value is determined using:

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

Here, Index Free Float Market Capitalisation = Current shares outstanding * IWF * Capping factor * Price. The index undergoes a semi-annual review using data from January 31st and July 31st, with stock replacements, if needed, implemented on the last trading day of March and September.
