Zee was already weak for some time now and that is one of the reason the stock price was down. But the real trigger on 17 March was rightly said the ED summons to the chairman of Zee. In fact, Naresh Goyal of Jet Airways and Subhash Chandra of Zee have been summoned on 18 March in connection with their deals with Yes Bank. Before that the promoters of DHFL are already summoned on 17 March by the ED in the Yes Bank case. In addition, Anil Ambani has been summoned on 19 while Gautam Thapar of CG has been summoned on the 21 of March. All these are in connection with the deals with Rana’s Yes Bank. Rana is already in judicial custody as of now.
