Sensex edges lower from five-week highs as telecom stocks slump

MUMBAI (Reuters) - The BSE Sensex fell on Thursday after earlier marking its highest levels in five weeks as mobile carriers such as Idea Cellular slumped on possible high bidding prices at a spectrum auction next month after eight companies applied to bid.

Idea Cellular Ltd slumped 7.5 percent, marking its biggest single-day percentage fall since May 2010, while Bharti Airtel Ltd provisionally fell 5 percent, the most since September 2013.

The benchmark BSE Sensex provisionally fell 0.21 percent, while the broader Nifty ended down 0.1 percent, after earlier marking their highest intraday levels since December 9.
