Benchmark Sensex and Nifty tumbled more than 1 per cent on Thursday after a two-day rally as investors remained on the sidelines ahead of the US Federal Reserve interest rate decision and unabated foreign fund outflows. The BSE Sensex tanked 836.34 points or 1.04 per cent to settle at 79,541.79.
During the day, it slumped 958.79 points or 1.19 per cent to 79,419.34. The NSE Nifty dropped 284.70 points or 1.16 per cent to finish at 24,199.35. From the 30-share Sensex pack, Tata Motors, Tech Mahindra, UltraTech Cement, JSW Steel, Sun Pharma, Asian Paints, IndusInd Bank and ICICI Bank were the major losers. State Bank of India emerged as the only gainer from the pack.
