Nifty Semi Annual Review - Expected Changes


The NIFTY 50 is the flagship index on the NSE. The Index tracks the behaviour of 50 blue-chip companies selected from the universe of NIFTY 100 based on free-float market capitalization. The methodology also takes into account constituent changes in the index and corporate actions such as stock splits, rights issuance, etc., without affecting the index value.  The NIFTY 50 stocks represent about 66% of the total float adjusted market capitalization of the National Stock Exchange (NSE). It covers major sectors of the Indian economy and offers investment managers exposure to the Indian market in one efficient portfolio.

The review of NIFTY 50 is undertaken semi-annually based on data for six months ending January and July. The replacement of stocks in NIFTY 50 (if any) is generally implemented from the first working day after F&O expiry of March and September. In case of any replacement in the index, a four weeks’ prior notice is given to the market participants.
