Nifty 50, also known as the National Stock Exchange Fifty or simply Nifty, is a benchmark stock market index of the National Stock Exchange of India (NSE). It was introduced in April 1996 and comprises the 50 largest and most liquid companies listed on the NSE. The Nifty 50 is widely considered as one of the most important indices of the Indian equity market.
The Nifty 50 index is calculated using free-float market capitalization weighted methodology, which means that the weightage of each company in the index is based on its market capitalization multiplied by the free-float factor. The free-float factor represents the proportion of shares that are available for trading in the market, after excluding shares that are held by promoters, governments, and strategic investors.
The Nifty 50 index provides a snapshot of the overall performance of the Indian stock market, as it includes companies from various sectors such as banking, information technology, energy, consumer goods, and healthcare. The index is also a popular tool for investors to track the performance of their investments, as it reflects the collective movement of the top 50 companies in the market.
The companies included in the Nifty 50 are periodically reviewed and replaced if they no longer meet the eligibility criteria. The eligibility criteria for inclusion in the Nifty 50 index include:
1. The company must be listed on the NSE.
2. The company must have a listing history of at least six months.
3. The company must have a free-float market capitalization of at least INR 20 billion.
4. The company must have traded at an average impact cost of 0.5% or less during the last six months.
