The Indian stock market closed higher on Thursday, with the S&P BSE Sensex up over 500 points and the Nifty50 ending above 18200 levels. Telecom, banks, metal, and public sectors all contributed to the rally, while sell-offs were seen in FMCG stocks. Usha Martin, Cholamandalam Investment and M&M Financial Services emerged as some of the key gainers. Equity analyst Amol Athawale suggests buying Usha Martin, profiting off Cholamandalam Investment, and buying M&M Financial Services after a short-term correction.
