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.
