Moody’s Investor Service downgraded Bharti Airtel Ltd. to junk. The downgrade comes on concerns that cash-flow generation for the telecom biggie will remain tepid for several quarters to come. This marks the first time an international rating agency has downgraded the stock. Bharti Airtel was at number one spot three years ago but is now at risk of dropping to third position as it tries to consolidate it’s business. Moody's expects profits from Bharti's Indian mobile segment to remain low, without a change in its pricing strategy.
