Snapping its five-day rising streak, equity benchmark Sensex closed 346 points lower after a highly volatile session on Wednesday, dragged by losses in index heavyweights Reliance Industries, Infosys and TCS amid weak cues from global peers. After opening on a positive note, the 30-share index sank 594.26 points from the day's high and finally settled 345.51 points, or 0.95 per cent, lower at 36,329.01. Similarly, the NSE Nifty dropped 93.90 points, or 0.87 per cent, to close at 10,705.75. Bajaj Finance was the top laggard in the Sensex pack, tumbling over 4 per cent, followed by Asian Paints, Bajaj Finserv, HCL Tech, Maruti and Infosys. On the other hand, IndusInd Bank, SBI, HUL, Tata Steel and ITC were among the gainers. -- PTI
