Asia’s oldest stock exchange, BSE Ltd, and InterGlobe Aviation Ltd., operator of budget carrier IndiGo, are likely to be added to India’s benchmark Nifty 50 index at the National Stock Exchange’s semi-annual review in August, according to multiple media reports citing people familiar with the process. The shake-up would remove IndusInd Bank Ltd. and two-wheeler maker Hero MotoCorp Ltd. from the 50-stock gauge, with the changes expected to take effect in September once the review is ratified. BSE qualifies despite being listed solely on the NSE, meeting free-float market-capitalisation and liquidity thresholds. Its shares have surged roughly 120% from March lows on rising derivatives activity. IndiGo has climbed about 22% in the past six months as air-travel demand rebounds. IndusInd Bank has fallen about 11% over the same period amid fraud and regulatory concerns, while Hero MotoCorp has struggled with tepid demand and higher financing costs. The Nifty 50 is rebalanced twice a year using six-month trading data, and index changes typically spur passive fund inflows for entrants and outflows for those deleted.
