Mumbai: Led by ICICI Bank and RIL, the Sensex Friday surged over 337 points -- the biggest single day gain in two months -- on all-round buying by funds after European Central Bank announced a potentially unlimited bond-buying plan to revive Eurozone's ailing economies.
The BSE benchmark index, which had gained 33 points ahead of the ECB meet yesterday, was off to a rollicking start today tracking overnight gains in US stocks and early Asian cues.
The 30-share Sensex opened 229 points higher and thereafter built on gains with ICICI Bank, RIL, Infosys and L&T leading the rise. Sensex finally ended at 17,683.73, up 337.46 points, or 1.95 percent.
The Sensex's gains were supported by Tata Steel that rose 5.72 percent, Tata Motors (4.40 percent), Hindalco (3.39 percent) and Sterlite (2.83 percent).
Today was the best single day performance since June 29 when Sensex rose by 439 points. Overall, nearly 1,800 stocks rose and investor wealth surged by Rs 84,000 crore.
Brokers said trading sentiment was bolstered as ECB's new bond buying plan will likely lower the borrowing costs for the region's debt-ridden nations and ease fears over euro's fate.
Capital stocks were among the best performers on the back of foreign funds flow while realty and metal stocks were also among the biggest gainers.
Most banking stocks, including ICICI Bank up 4.68 percent and SBI which gained 2 percent, also rose on expectations of a rate cut in RBI's policy meet on September 17, said dealers.
RIL rose 3.08 percent to Rs 791 on reports of a foreign upgrading its rating.
