Market Roundup: Sensex sheds 173 pts amid F&O expiry; Nifty slips below 11,700

Mumbai: Equity benchmark Sensex tumbled 173 points on Thursday, tracking losses in index majors HDFC twins, L&T and HUL as volatility persisted amid expiry of monthly derivatives contracts. Lacklustre cues from global markets also kept domestic investors on the edge, traders said. The 30-share BSE Sensex ended 172.61 points or 0.43 per cent lower at 39,749.85. The broader NSE Nifty fell 58.80 points or 0.50 per cent to 11,670.80.
