Trading sentiment turned bullish following a rise in global stock markets after US manufacturing increased last month, easing concern world's biggest economy will fall into a recession.
The Institute for Supply Management's manufacturing index rose to 50.7 in January from 48.4 in the previous month.
Reliance, which runs the world's third biggest refinery, gained Rs 85.35 to Rs 2,627. ICICI, country's second-largest lender, climbed Rs 34.20 to Rs 1,231.95. The two stocks account for about a quarter of the Sensex's weight.
