Mumbai: The BSE Sensex on Friday zoomed 516 points, biggest jump in two months, on funds buying blue-chips such as RIL and Infosys amid global rally on easing euro-zone debt crisis and hopes of a pause in RBI rate hikes.

Sensex, which had gained over 500 points in the last three trading sessions, shot up 515.97 or 2.98 per cent to 17,804.80, recording biggest one-day jump after August 29. It touched the day's high of 17,908.13.

Similarly, the broad-based National Stock Exchange index Nifty zoomed past 5,300 level, ending with a gain of 158.90 points or 3.05 per cent at 5,360.70.

Metal, realty and banking sector stocks gained by up to 6.34 per cent.

A firm trend in global markets followed European leaders' pact to expand a bailout fund to stem euro-zone's debt crisis and growth in the US economy.

Besides, Reserve Bank of India (RBI) hinted earlier this week that it may pause hiking lending rates. RBI has raised the lending rate by 375 basis points since mid-March 2010 to tame high inflation.

The two most-heaviest on the Sensex, with 20 per cent weight, Reliance Industries and Infosys Ltd ended with handsome gains. The RIL spurted by 2.82 per cent and Infosys by 0.74 per cent.

In the 30-share BSE index, barring Bharti Airtel, Bajaj Auto and Maruti Suzuki, 27 stocks ended with gains.

The metal sector index was the star performer, up 6.34 per cent to 12,142.72.
