About Nifty 50

NIFTY 50 & History

The NIFTY 50 is the flagship index on the National Stock Exchange of India (NSE). It includes 50 of all companies listed on the NSE. The index, trading since April 22, 1996, covers 13 major sectors of the Indian economy. The NIFTY 50 is owned and managed by NSE Indices (previously known as India Index Services & Products Limited, India's first specialised company focused on an index as a core product). The index captures approximately 65 percent of its float-adjusted market capitalisation and is a true reflection of the Indian stock market. NIFTY 50 is one of the two main stock indices used in India, the other being the BSE SENSEX.​

NIFTY 50 selection criteria

  • The security should have traded at an average impact cost of 0.50% or less during the last six months for 90% of the observations for a basket size of Rs. 2 crore. Impact cost is cost of executing a transaction in a security in proportion to the weightage of its free float market capitalisation as against the index free float market capitalisation at any point of time. This is the percentage mark-up suffered while buying / selling the desired quantity of a security compared to its ideal price (best buy + best sell)
  • A company which comes out with an IPO will be eligible for inclusion in the index if it fulfils the normal eligibility criteria for the index like impact cost, market capitalisation and floating stock, for a 3-month period instead of a 6-month period.
  • The constituents should be available for trading in the derivatives segment (Stock Futures & Options market) on NSE.
  • A stock may be replaced from an index due corporate actions, delisting etc. In such a scenario, the stock having largest free float market capitalisation and satisfying other requirements related to liquidity, turnover and free float will be considered for inclusion.
  • A stock may be replaced also when a better candidate is available in the replacement pool. For example, if a stock with the highest free float market capitalisation in the replacement pool has at least twice the free float market capitalisation of the index stock with the lowest free float market capitalisation. But a maximum of 10% of the index size (number of stocks in the index) may be changed in a calendar year.
