The Sensex plunged 800 points while the Nifty slipped below 24,300, driven by widespread selling across sectors. Metal stocks were the hardest hit, with the Nifty Metal index sliding 2.4%. Steel giants like JSW Steel, Tata Steel, NMDC, and SAIL saw losses of 3-5%, impacted by uncertainty over China's policy measures. A stronger dollar, rising U.S. Treasury yields, and weak Asian markets added to the pressure. By 9:50 AM, Sensex fell 568 points to 80,721, while 2,143 stocks declined, highlighting market pessimism.
