Equity benchmarks Sensex and Nifty opened on a choppy note on Wednesday, led by weakness in index-heavyweight IT stocks amid tepid cues from global markets. Despite opening with mild gains, the 30-share Sensex turned volatile to trade 41.84 points or 0.07 per cent lower at 58,237.64. Similarly, Nifty slipped 15.35 points or 0.09 per cent to 17,346.75 in initial deals.

Infosys was the top loser in the Sensex pack, shedding over 1 per cent, followed by PowerGrid, HCL Tech, TCS, Tech Mahindra, Maruti and Bajaj Auto. On the other hand, Bharti Airtel, IndusInd Bank, NTPC, Axis Bank, ITC, ICICI Bank, SBI and Bajaj Finance were among the gainers.
