Shares in companies controlled by billionaire Gautam Adani shed quite $6 billion on Monday despite rejecting media reports that said accounts of three investor funds that own stocks had been frozen. Adani Group flagship Adani Enterprises closed down 6.3 percent after plunging the maximum amount as 25 percent, its steepest fall in nearly a decade. The freezing of the three accounts was first flagged in a piece of writing within the Economic Times on Monday. The Adani Group firms involved rejected reports about the NSDL freezing the funds’ accounts as “blatantly erroneous” in identical statements issued to stock exchanges.
