The Bombay Stock Exchange benchmark Sensex on Thursday shot up by over 175 points in early trade on buying by funds as well as retail investors in heavy-weight stocks, triggered by firming global markets.
The 30-share index, which had gained 225.49 points on Wednesday in volatile trade, moved up by another 175.10 points to 17,153.45 in the first five minutes of trade.
Similarly, the National Stock Exchange index Nifty surged by 48.35 points to 5,060.10.
Marketmen said firming trends in the global markets mainly fuelled fresh buying by funds in index-related stocks.
They said with the improvement in the sentiments, buying interest was also seen in mid-cap and non-sensex stocks.
Major gainers which supported the Sensex were Reliance Industries, Reliance Energy, BHEL, Larsen and Toubro, Tata Steel, Maruti, Grasim Industries, ACC, Sterlite Industries, Hindalco, State Bank of India and Infosys Technologies.
