The benchmark BSE Sensex fell over 100 points in early session on Tuesday, breaking its three-day winning run as metal, IT, realty and banking stocks retreated, tracking sell-off in the global market.

The 30-share index dropped 104.41 points, or 0.29 per cent, to 35,670.47 points in opening trade. The gauge had rallied about 633 points in the previous three sessions.

The NSE Nifty, too, fell 36.80 points, or 0.33 per cent, to 10,726.60.

Brokers said besides a weak trend at other Asian markets amid sharp losses at the Wall Street, profit-booking by investors in recent gainers also dampened the sentiment here.

Meanwhile, signalling a temporary truce, the Reserve Bank and the government on Monday agreed to refer to an expert committee for the contentious issue of appropriate size of reserves that the RBI must hold, while restructuring of stressed loans of small businesses would be considered by the central bank.
