Mumbai Aug 30 (IANS) Profit booking ahead of the August futures and options expiry and a weak rupee subdued the key Indian indices on Thursday.
Both the key indices -- S&P BSE Sensex and NSE Nifty50 -- ended marginally lower paring their major losses made earlier in the day.
The Indian currency earlier in the day plunged to 70.81-82 per dollar the lowest-ever level which dampened the domestic investor sentiments.
At 3.30 p.m. the Nifty50 on the National Stock Exchange (NSE) provisionally closed at 11 676.80 points lower by 15.10 points or 0.13 per cent from its previous close.
The benchmark BSE Sensex which had opened at 38 796.98 points provisionally closed at 38 690.10 points lower by 32.83 points or 0.08 per cent from the previous close of 38 722.93 points.
It touched an intra-day high of 38 819.06 points and a low of 38 581.83 points.
The top gainers on the Sensex were Sun Pharma Tata Steel ITC Bharti Airtel NTPC; while Maruti Suzuki IndusInd Bank Reliance Industries Tata Motors(DVR) and Axis Bank lost the most.
