After months of selling Indian equities aggressively, foreign portfolio investors (FPIs) seem to be making a comeback. Net FPI inflows have hit Rs 54,925 crore ($5.8 billion) over the past three weeks – a sharp reversal from the relentless selling that weighed on Indian equities. Experts say that several reasons have contributed to this. These include, a sharp fall in crude oil prices, improving corporate earnings and growing unease over the artificial intelligence (AI) boom in global markets.
