Bharti Airtel fell by 2.43 per cent to end at Rs 393.35 on the BSE. Bajaj Auto lost 1.08 per cent to Rs 2,612.40.
Marketmen said that selling pressure was seen in these stocks on concerns that exports to Nigeria will be hit following devaluation of their currency.
Nigeria has devalued its currency Naira to the US Dollar by over 8 per cent to about 168 per dollar and at the same time, it has raised key interest rate to a record high.
Nigeria is also Bharti Airtel's biggest market in Africa.
