Indian equity benchmarks saw a major selloff on Friday, with investors rushing to cut exposure amid concerns over weak monsoon forecasts, continued foreign fund outflows, and lingering geopolitical uncertainty. The sharp decline dragged both the Sensex and Nifty deep into the red, erasing nearly Rs 5 lakh crore in investor wealth in a single session. The BSE Sensex plunged 1,092 points to settle at 74,775.74, while the NSE Nifty 50 slid more than 359 points to close at 23,547.75.
