Technical Analyst, Ashwani Gujral is of the view that one can buy Bharti Airtel.

Gujral told CNBC-TV18, "Yesterday there was a significant statement made that people were shorting Bharti Airtel and buying MTN. That was a great place to be buying Bharti Airtel around Rs 815-820 and this short covering can probably take the stock back upto Rs 900. So Bharti Airtel is definitely a buy right now."

Disclosure: It is safe to assume that analyst and his clients may have an interest in the above stock/sector.
