Nifty Bank

The Nifty Bank Index tracks 14 major banking stocks listed on the National Stock Exchange using the free-float market capitalisation method. 

The index includes selected public and private sector banks that meet the eligibility criteria set by the NSE. It represents the banking sector rather than the broader equity market. 

The index is reviewed periodically. Changes in constituent stocks and their free-float market capitalisation can alter the index composition and weightings after each rebalancing.

The Nifty Bank Index is calculated using the free-float market capitalisation method. Only shares available for public trading are considered while calculating the index value. 

The basic calculation is: 

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

For example, suppose three banks have free-float market capitalisations of ₹100 crore, ₹80 crore and ₹20 crore. Their combined value is ₹200 crore. If the combined value later rises to ₹220 crore, the index would increase proportionately, assuming no changes in the base value. 

This method gives greater influence to banks with higher free-float market capitalisation. 

The following table summarises the main criteria used for selecting stocks in the Nifty Bank Index.

The Nifty Bank Index consists of 14 banking stocks. Their weightages are based on free-float market capitalisation.

The weightages are refreshed during NSE's periodic index reviews and may change after rebalancing.  

Bank Nifty works by combining the price movements of its constituent banking stocks into a single index value. Each stock contributes according to its free-float market capitalisation. 

If higher-weighted banks move significantly, they can have a larger effect on the index. The index is reviewed and rebalanced periodically to reflect changes in market capitalisation and eligibility. It is also used as the underlying index for futures and options contracts on the NSE.

The following are a few benefits of gaining exposure to the Nifty Bank Index.

• Market Tracking: It reflects the overall movement of the banking sector.
• Liquidity: The index is widely tracked and has related exchange-traded products.
• Transparency: Constituents and index methodology are published by the NSE.

Investors can access the index through products such as Bank Nifty exchange-traded funds (ETFs) or index funds, where available.

The Nifty Bank Index was introduced by the NSE in 2003 to measure the performance of the banking sector. It started with a base value of 1,000.

Since its launch, the index has gone through several market cycles, including the global financial crisis and the COVID-19 market decline. The constituent stocks and their weightages have also changed through periodic rebalancing to reflect the evolving banking sector.
