The BSE Sensex dropped 178 points, or 0.2%, to 83,359 in morning trade on Thursday, extending its decline for a second consecutive session as traders weighed the prospects of a potential US-India trade deal. Investors also braced for the start of the June quarter earnings season, with TCS scheduled to announce its results later today. In a volatile session, the pharmaceutical and healthcare sectors led losses, each falling 0.7%, amid US plans to impose a 200% tariff on pharmaceutical imports. Meanwhile, the tech sector declined 0.5%, and consumer goods slipped 0.3%. The fall was somewhat limited by the Fed meeting minutes, which indicated expectations of interest rate cuts later this year. Additionally, an upbeat session on Wall Street overnight - fueled by a rally in the tech sector - helped prevent further declines in the index. Among the bottom performers were Bharti Airtel (-1.3%), HCL Tech (-1.0%), Infosys (-0.9%), Tech Mahindra (-0.8%), Asian Paints (-0.8%), and TCS (-0.2%).
