Bharti Airtel can give 15-20% upside: Diwan

Diwan told CNBC-TV18, "Bharti Airtel is a good stock and in the long run it definitely can provide you that kind of an upside. But essentially at the current levels I don’t think you need to go overboard. But in case there is a possibility it comes down because it is sensitive to regulatory changes, you could average down at a lower price. I won't advise you to buy more at this point in time but you can definitely hold on to what you have and expect at least about a 15-20% kind of upside in the next 6 months."
