Indian stock markets tumbled in early trade on Monday amid rising US-Iran tensions after US airstrikes on Iran’s nuclear sites. The Sensex dropped 791.58 points to 81,616.59 and Nifty fell 244.25 points to 24,868.15 by 9:53 am. IT stocks led the decline, with Infosys down 2.01%. Other major losers included HUL, Asian Paints, and HCL Tech. Only Nifty Media saw slight gains, while most sectoral indices opened in the red. Dr. VK Vijayakumar of Geojit said the market impact may be limited unless Iran’s response escalates. Broader indices also weakened, while India VIX rose 4.86%, indicating increased market volatility.
