India's BSE Sensex lost further ground to close about 1% down at 81,692 on Thursday, the lowest since mid-May, halting slight gains from yesterday. Investors opted for profit-booking amid uncertainties surrounding the US-China trade deal and rising tensions in the Middle East, along with renewed tariff threats by President Donald Trump. A plane crash in western India further dampened sentiment. On the domestic data front, inflation for May drew attention, following a positive US inflation report the day before that raised expectations of interest rate cuts by the Federal Reserve. On the corporate front, multiple sectors saw losses. Tata Motors was the top loser, falling 2.98%, followed by Titan (-2.62%) and Eternal (-2.3%). Asian Paints, Bajaj Finserv and Tech Mahindra were the only gainers.
