MUMBAI: Helped by a smart rebound in rupee after current account gap moderated sharply, the S&P BSE sensex on Thursday surged by 324 points to end at one-week high of 18,875.95 on strong gains in RIL, HDFC Bank and Infosys. 
Hectic short-covering activity on last day of June derivative series as well as hopes of US Fed possibly delaying the planned tapering of monetary stimulus, also boosted the Indian markets, traders said. Investor wealth rose by over Rs 1 lakh crore as overall more than 1,200 stocks gained. 

The BSE 30-share gauge resumed higher following firm Asian cues triggered by strong rally on Wall Street yesterday and remained in positive terrain before settling at 18,875.95, a rise of 323.83 points or 1.75 per cent. This is its highest close since 19,245.70 on June 19.
