BSE enters India's benchmark Nifty 50, replacing Wipro after a 6-month average free-float market cap of ₹1.4 lakh crore. The reshuffle triggers passive fund rebalancing by September 29.
BSE, India's oldest stock exchange, will join the Nifty 50 index on September 30, replacing Wipro in the National Stock Exchange's half-yearly rebalance. The move reflects a shift in market capitalisation: BSE's six-month average free-float market cap stood at ₹1,40,879 crore, more than double Wipro's ₹55,930 crore, NSE said on Monday. The changes take effect after the close of trading on September 29.
Under the methodology, an incoming stock must have a free-float market capitalisation at least 1.5 times that of the smallest existing Nifty 50 constituent. TVS Motor Company and Divi's Laboratories, with respective averages of ₹84,566 crore and ₹82,930 crore, fell short of that threshold, NSE said.
Wipro, which exits the benchmark, will move to the Nifty Next 50. The tech firm's WIT stock page carries an Alpha Score of 46/100, labelled Mixed, reflecting middling momentum and valuation signals. Its departure from the Nifty 50 means passive funds tracking the index will need to sell roughly ₹5,000–6,000 crore of Wipro stock and buy a similar amount of BSE, based on free-float weighting.
Broader index reshuffles accompany the change. Hitachi Energy India, Polycab India, Vedanta Aluminium Metal and Vodafone Idea will enter the Nifty 100, replacing Indian Hotels, Lodha Developers, REC, Shree Cement and United Spirits. In the Nifty 200, Life Insurance Corporation of India, Meesho, Bank of Maharashtra, Hindustan Copper, NLC India and REC are added. The Nifty Midcap 100 loses 10 stocks, including BSE, Alkem Laboratories and Hitachi Energy India, which graduate to the large-cap indices. The Nifty 500 will see 27 additions and 27 deletions.
For index-tracking funds, the September rebalance is the most consequential in several quarters. The simultaneous promotion of multiple stocks from mid- to large-cap – and the exit of a heavyweight like Wipro – will force portfolio managers to adjust positions across a spectrum of holdings. Liquidity in some of the incoming names, particularly Meesho and Vodafone Idea, could amplify execution costs during the rebalance window.
BSE's inclusion caps a years-long rally in the exchange's shares, driven by record derivatives volumes and a widening retail footprint. The stock now commands a free-float weight that places it among the top 20 Nifty 50 constituents by market cap, NSE data show.
