The wide-based National Stock index Nifty crossed 4,800-points level for the first time in almost 15 months, while the BSE benchmark Sensex surged by over 122 points in opening trade on Tuesday on increased inflow of foreign funds driven by firming trends in other Asian markets.
The broader-based National Stock Exchange index, Nifty, rose by 38.40 points to 4,821.30 points- a level last seen on June 2, 2008.
The 30-share BSE Sensex shot up by 122.11 points to trade at the years high of 16,139.27 points in opening trade with most of the heavyweight stocks quoting in positive territory.
The BSE barometer had rallied almost 617 points in the past two trading sessions.
Brokers said buying activity in the domestic markets picked up momentum largely on the back of a firming trend in other Asian equity markets, which were up almost 0.80 per cent in morning trade.
Major gainers, which supported the indices were Reliance Industries, Larsen and Toubro, BHEL, Tata Steel, Hero Honda Motors and State Bank of India.
