Introduced in 2003, the index helps investors monitor the banking sector, compare portfolio performance, and analyse market trends. It is also used as the underlying index for futures and options contracts.

Key points:

• Tracks 12 banking stocks listed on the NSE.
• Introduced in 2003 to represent India's banking sector.

• Serves as a benchmark for investors, fund managers, and financial products.

To understand Bank Nifty, it is helpful to know how the broader Nifty 50 index is structured.

Nifty 50 tracks the performance of 50 large companies listed on the National Stock Exchange across multiple sectors of the Indian economy.

The sectors represented include:

• Information technology
• Financial services
• Consumer goods
• Entertainment and media
• Metals
• Pharmaceuticals
• Telecommunications
• Cement and related products
• Automobiles
• Pesticides and fertilisers
• Energy
• Other services

While Nifty 50 represents multiple industries, Bank Nifty focuses exclusively on banking stocks.

Nifty is calculated using the free-float market capitalisation-weighted methodology. Under this approach, only shares available for public trading are considered while determining the weight of each company in the index.

The calculation is based on the following formula:

Nifty = Current market value ÷ Base market capital × 1000

For Nifty, the:

• Base date is 3 November 1995
• Base value is 1000
• Base market capital ₹2.06 lakh crore 

Free-float market capitalisation is calculated as:

Share price × Equity capital × Investable Weight Factor (IWF)

This methodology ensures that companies with larger free-float market capitalisation have a greater influence on index movements.

The Bank Nifty Index follows defined selection criteria to ensure it represents the banking sector effectively. Companies are evaluated using multiple parameters before being included in the index.

Liquidity

Stocks must demonstrate sufficient trading liquidity to qualify for inclusion. Higher liquidity supports efficient price discovery and allows the index to respond more accurately to changing market conditions.

Market capitalisation

Market capitalisation is another important selection factor. Companies with larger market capitalisation generally have a greater influence within the banking sector and are therefore more likely to qualify for inclusion.

Sector representation

The index aims to represent the Indian banking industry by including both public and private sector banks. This balanced representation provides a broader view of the sector's overall performance.

Corporate governance

Companies considered for inclusion are also assessed on their corporate governance practices. Organisations with transparent operations and established governance standards help strengthen confidence in the index and support its credibility.

Financial performance

The index includes banks with a record of sound financial performance and consistent profitability. This criterion helps ensure that the index represents established participants in India's banking sector.
