Indian stock markets opened lower, with the Sensex slipping by 82 points and the Nifty 50 dropping below the 25,900 mark. The cautious investor sentiment is largely attributed to ongoing trade negotiations between India and the US, which have created uncertainties in the market. Analysts note that until there is more clarity on the trade discussions, investor confidence remains fragile. The broader market also showed weakness, with sectors sensitive to global trade fluctuations, such as IT and pharmaceuticals, facing downward pressure in early trading.
