IndusInd Bank and Hero MotoCorp may be dropped from the Nifty50 in the September review, with Max Healthcare and IndiGo likely replacements, according to Nuvama. Max could see $400 million in passive inflows if included. BSE is unlikely to enter the Nifty50 or even the Nifty Next 50 unless its stock surges over 40% and sustains the rally through July.
