Dalal Street, the Indian stock market, saw a surge in the sensex, closing at 66,079 with a 567-point gain on Tuesday. This increase was attributed to strong buying by domestic investors and short-covering by speculators, despite foreign investors being net sellers. Falling crude oil prices also contributed to improved investor sentiment. Stocks from various sectors, including ICICI Bank, Infosys, and HDFC Bank, played a significant role in this gain.
