Indian benchmark indices, Sensex and Nifty, closed lower on Wednesday, ending their eight-day rally as investors exercised caution ahead of the US Federal Reserve's interest rate decision and mixed global market trends. The 30-share BSE Sensex lost 161.41 points or 0.26% to settle at 61,193.30, while the broader NSE Nifty fell 57.80 points or 0.32% to end at 18,089.85. Stocks of information technology, metals and public sector banks witnessed a decline of roughly 1% each. Reliance Industries, Tata Consultancy Services, Infosys, and Larsen & Toubro were among the index majors that added to the weak trends in equity, while Hindustan Unilever, Asian Paints, Tata Motors, UltraTech Cement, ITC, and Nestle ended among the gainers. The caution ahead of the Fed's decision was also prompted partly by fears among investors that any upward rate hike could lead major economies into a recession and hinder growth. Foreign institutional investors, however, bought equities worth Rs. 1,997.35 crore according to exchange data.
