Eligibility Criteria for Nifty 50 Index Listing

To be included in the Nifty 50 Index, a company must satisfy certain eligibility requirements prescribed by NSE Indices. 

• Domicile and Listing Requirements

The company must be domiciled in India and listed on the National Stock Exchange (NSE). The security should be available for trading on the NSE and meet the exchange's listing and trading requirements.

• Inclusion in the Nifty 50 100 Universe

Generally, only stocks that are part of the Nifty 50 100 Index are considered for inclusion in the Nifty 50 Index. This ensures that eligible companies already belong to the broader universe of large and liquid listed stocks.

• Eligibility in the Futures and Options (F&O) Segment

The stock should be eligible for trading in the NSE Futures and Options (F&O) segment. This requirement helps ensure sufficient market participation and liquidity.

• Liquidity Requirements

The stock must demonstrate adequate liquidity over a specified review period. NSE Indices evaluates liquidity using measures such as impact cost, which reflects the potential price change resulting from a transaction of a defined value.

• Free-Float Market Capitalisation

A company's free-float market capitalisation plays a key role in determining eligibility. Free-float market capitalisation refers to the market value of shares readily available for trading by the public, excluding promoter holdings and other restricted shares.

• Trading Frequency

To qualify for inclusion, the stock is generally required to maintain a high trading frequency over the review period. Regular trading activity helps ensure that the stock remains sufficiently liquid for index tracking and investment purposes.

• Differential Voting Rights (DVR) Shares

Equity shares with differential voting rights may be considered for inclusion, subject to meeting specific free-float market capitalisation and liquidity requirements prescribed by NSE Indices.

• Eligibility of Recently Listed Companies

Recently listed companies, including those that have completed an Initial Public Offering (IPO), may be considered for inclusion if they satisfy the prescribed criteria relating to free-float market capitalisation, liquidity, and trading history within the specified evaluation period.

• Periodic Review and Rebalancing

The Nifty 50 Index is reviewed periodically to ensure that constituent stocks continue to meet the eligibility requirements. Companies that no longer satisfy the criteria may be replaced by eligible stocks that more accurately represent the index objectives.
