Markets regulator SEBI has asked the Supreme Court for more time for its investigation into the allegations levelled by US-based short-seller Hindenburg on billionaire Gautam Adani's conglomerate. Earlier On March 2, the Supreme Court set up an expert committee amid the controversy arising out of a report by US short-seller Hindenburg Research on the Adani Group. It directed SEBI to investigate whether there has been a violation of Section 19 of SEBI rules and any manipulation of stock prices.
