During mid-morning trading, the S&P BSE Sensex plunged 1,126.31 points or 1.45%, settling at 76,370.05. The decline was primarily driven by rising oil prices and a weakening Indian rupee, which reached a record low. The Nifty 50 index also fell 348.10 points or 1.44%, dropping below the 23,850 mark to close at 23,830. Realty stocks faced significant pressure, with the Nifty Realty index declining 2.17% after a previous gain. Key players like Aditya Birla Real Estate and DLF saw declines of 3.10% and 1.83%, respectively. The broader market also reflected this downturn, with the BSE 150 MidCap Index down 1.38% and the BSE 250 SmallCap Index down 0.95%. Investor sentiment was further dampened by continued selling from foreign institutional investors and the approaching monthly Sensex derivatives expiry, which heightened volatility. The NSE's India VIX, a measure of market volatility, surged 10.36% to 19.25. In contrast, Mphasis reported a 15.26% increase in net profit, boosting its stock by 2.31%.
