The Most Dramatic Index Reshuffle in Years | BSE Enters Nifty 50

Stock exchange BSE will be included in the Nifty 50 index as part of the semi-annual review by NSE Indices, replacing IT firm Wipro, with the changes effective September 30, 2026. That announcement dropped Monday evening — and it immediately changed the conversation for two very different stocks. BSE's inclusion is based on its six-month average free-float market capitalisation of Rs 1.40 lakh crore, at least 1.5 times that of Wipro, whose average free-float market cap stood at Rs 55,930 crore. The gap between the two numbers tells the entire story of what AI disruption anxiety has done to India's IT sector over the past 18 months. BSE's scrip rallied 4 per cent on Monday in anticipation of the inclusion, ending at Rs 3,596 per share. For $WIPRO , the exit is more than symbolic. The switch comes as concerns over artificial intelligence and slowing global technology spending weigh on India's biggest software services firms, making Wipro's Nifty exit a reflection of structural market forces rather than a one-off corporate event. The stock is down over 30 per cent from its 52-week high and carries among the lowest valuations in the large-cap IT pack. Beyond the headline change, NSE also rejjigged several indices — Nifty 100, Nifty 500, Nifty SmallCap 250, Nifty MidCap 150 and Nifty Next 50, with BSE, Hitachi Energy India, Polycab India, Vedanta Aluminium Metal and Vodafone Idea among the Nifty 100 entrants. Wednesday's session will be the first full trading day after these announcements. Passive index funds and ETFs tracking the Nifty 50 will need to buy BSE and sell Wipro before September 30 — and that forced buying will be one of the most closely tracked institutional flows of the quarter.
