Indian stock markets closed marginally lower on Thursday, with the Sensex falling 32 points and the Nifty50 ending slightly up. The decline was primarily driven by significant losses in FMCG stocks, particularly ITC and Godfrey Phillips, which experienced sharp drops following a government announcement on new tobacco product cess. Gains in auto and IT sectors, along with select heavyweights like NTPC and Larsen & Toubro, helped to limit the overall market fall.
