The sell-off was primarily driven by uncertainty surrounding US President's planned 'Liberation Day' reciprocal tariffs scheduled for April 2. IT and banking sectors were most affected due to US market exposure. Among the 30 Sensex components, 28 declined, with HCL Tech, HDFC Bank, and Infosys among the biggest losers.
