The Bombay Stock Exchange (BSE) is set to enter India’s benchmark Nifty 50 index, replacing information technology major Wipro from September 30, 2026. The change was announced as part of the latest semi-annual review by NSE Indices and marks a significant shift in the composition of one of India’s most closely tracked stock market indices.
The move reflects the changing structure of India’s equity market. BSE’s six-month average free-float market capitalisation has risen significantly, allowing it to meet the eligibility requirement for inclusion in the Nifty 50. Under the index methodology, a stock must have a free-float market capitalisation at least 1.5 times that of the smallest Nifty 50 constituent for the replacement to take place. BSE met that threshold against Wipro.
For BSE, the inclusion is an important milestone. The stock exchange has seen a strong rally in its shares over the past year, helped by growing activity in India’s equity and derivatives markets. Its inclusion in the Nifty 50 will also increase its visibility among domestic and international investors.
BSE shares gained sharply after the replacement announcement, with the stock rising more than 3% during Monday’s trading session before paring some gains. The stock has been among the stronger performers in the financial market segment this year, reflecting expectations around the exchange’s expanding business and increased trading activity.
The Nifty 50 tracks 50 large and liquid companies listed on the National Stock Exchange. It is widely used as a benchmark by mutual funds, exchange-traded funds and other investment products. Passive funds that track the index generally adjust their holdings whenever the index composition changes.
That is why the BSE-Wipro switch could result in significant fund flows. Analysts estimate that passive funds could direct about $691 million towards BSE shares following its inclusion, while Wipro could see outflows of around $240 million as funds tracking the Nifty 50 remove the stock from their portfolios.
Such flows are largely mechanical and do not necessarily reflect a sudden change in the fundamental outlook for either company. Index funds are required to adjust their portfolios to match the new composition, creating additional buying demand for the incoming stock and selling pressure on the outgoing one.
For Wipro, the exclusion is a notable development. The IT services company has been a long-standing member of the Nifty 50, although it has faced sustained pressure in recent months. The company’s shares have declined significantly this year amid broader concerns over the outlook for Indian IT services companies.
One of the biggest issues confronting the sector is the growing use of artificial intelligence. Investors have been assessing whether rapid advances in AI could reduce demand for some traditional software and technology services, potentially affecting revenue growth and margins for established IT companies.
Wipro has also faced broader sector-wide concerns, with Indian IT stocks under pressure as investors reassess valuations and long-term growth prospects. The Nifty IT index has experienced a significant decline this year, reflecting these worries.
The Nifty 50 change does not mean Wipro is being removed from the stock market or that its business has become fundamentally weaker. It simply means that, under the index’s rules, another company currently has a stronger position based on market-capitalisation and liquidity criteria.
Wipro’s exit will nevertheless matter because of the large amount of money benchmarked to the Nifty 50. Index-tracking funds will have to reduce or eliminate their Wipro holdings as the new composition takes effect. This could create short-term selling pressure around the implementation date.
BSE, meanwhile, stands to benefit from the opposite effect. Funds tracking the benchmark will need to acquire the exchange’s shares, potentially creating additional demand. The company could also receive greater visibility among global investors who use the Nifty 50 as a primary gauge of Indian equities.
The inclusion is particularly interesting because BSE operates in the same broad capital-markets ecosystem as the National Stock Exchange. The exchange has been expanding its presence in equity derivatives and other market segments, benefiting from the rapid growth of retail participation in Indian financial markets.
India has seen a substantial increase in household participation in equities through direct investing, mutual funds and systematic investment plans. Rising participation has contributed to higher trading volumes and greater activity across the country’s stock exchanges.
The Nifty 50 reshuffle therefore reflects more than a change in two stocks. It highlights how quickly market leadership can change as companies grow, valuations shift and investor participation evolves.
For investors, the immediate focus will be on how BSE and Wipro shares behave between now and September 30. BSE could continue to attract attention because of expected passive fund buying, while Wipro may face pressure from index-related selling.
However, market participants are likely to distinguish between these technical flows and the companies’ underlying fundamentals. Once the index adjustment is completed, stock prices will ultimately depend on earnings, business growth, valuations and investor expectations.
The BSE inclusion also strengthens the exchange’s standing in India’s capital-market ecosystem. For Wipro, meanwhile, the exit represents a difficult phase for a company that has been a familiar name in the benchmark for years.
The Nifty 50 reshuffle will officially take effect on September 30. Until then, investors are likely to track BSE’s share-price performance, Wipro’s response and estimates of index-related fund flows. The change serves as another reminder that India’s benchmark index is constantly evolving with the changing fortunes of its listed companies.
