The mobile telephony major Vodafone Idea (Vi) stock is in the news for two major developments that have taken place in the last couple of days. The first one is with respect to the offer from its non-executive chairman Kumar Mangalam Birla to step down one and hand over the promoter’s stake to the government. The second one is related to government’s move to introduce a bill to scrap retrospective taxation. Because of these two developments that can impact the future growth prospects of the mobile-cellular company, existing shareholders are in a state of confusion and are unable to take an informed decision as to whether to continue with the stock or make an exit.
