The BSE Sensex fell 520 points, or 0.6%, to 81,735 in morning trade on Friday, extending losses from the previous session and hitting its lowest level in nearly four weeks. The decline was mainly driven by weakness in banking, financial services, realty, and tech sectors. Traders remained cautious amid ongoing uncertainty over trade deals with the U.S. ahead of the August 1 deadline. Concerns were also heightened as investors awaited earnings results from several companies, including Reliance Industries, which is set to announce its results later today. Axis Bank plunged 4.5%, set for its worst day in six months, after a surprise quarterly profit drop due to increased bad loans from a one-time industry benchmarking exercise. Meanwhile, LTIMindtree slipped 1.9% despite reporting earnings broadly in line with market expectations. For the week, the Sensex is on track for a 0.9% decline, marking its 3rd straight weekly drop amid ongoing uncertainty surrounding US–India trade negotiations.
