BSE Stock Poised for Massive Surge as it Replaces Wipro in Key Nifty 50 Index
The National Stock Exchange of India (NSE) has announced a significant shakeup to the Nifty 50 index, confirming that BSE Ltd. will replace technology firm Wipro starting September 30. This move is poised to trigger major passive fund flows as analysts track the shift in market capitalization between two long-standing constituents.BSE shares are set to join the benchmark index, marking a substantial endorsement of the exchange company's value and stability within the capital market landscape. The inclusion comes as BSE Ltd. has shown strong performance this year, posting gains of 36.8% so far.
Impact of Company Replacement on Passive Funds
The transition from Wipro to BSE is expected to result in substantial passive fund movement across the market. Nuvama Alternative and Quantitative Research estimates that while BSE may see inflows amounting to $741 million, Wipro is projected to incur passive outflows totaling $246 million. These flows are directly attributable to tracking funds adjusting their portfolios to align with the new Nifty constituents.Wipro Ltd., a long-term member of the 50-stock benchmark since January 17, 2002, is set to see declines as it exits the index. Conversely, BSE's entry signals increased recognition for its market influence within the NSE ecosystem.
Index Eligibility Criteria and Rationale
The NSE clarified that BSE Ltd. was included in the Nifty 50 based on specific free-float market capitalization criteria. The company maintained an average free-float market capitalization of ₹1,40,879 crores over a six-month period. This figure meets the mandate which requires it to be at least 1.5 times the 6-month average free-float market capitalization of the smallest existing constituent, Wipro Ltd., which stands at ₹55,930 crores.The index review also addressed two other high-potential candidates that did not meet the selection threshold for inclusion in the Nifty 50. TVS Motor Company and Divi's Laboratories were determined to be outside the scope of the current index composition.
Broader NSE Index Changes Announced
Beyond the notable change involving BSE Ltd., the National Stock Exchange also provided updates regarding other benchmark indexes. The exchange announced changes affecting the broader Nifty 500, Nifty 100, and Nifty Next 50 lists. These adjustments reflect a continuous calibration of index weights and constituents to mirror current market dynamics across different segments.In contrast to BSE's strong showing, Wipro is currently facing significant pressure in the stock market, having fallen by 1.1% at the close of the day after it had been down 30.6% so far in 2026.
