On October 22, the Sensex and Nifty fell over 1% amid a broad-based sell-off, driven by rising US treasury yields and disappointing Q2 earnings. The Sensex dropped 931 points to 80,220, while the Nifty declined 309 points to 24,472, with heightened market volatility reflected in a 4% spike in the India VIX. Financials, oil & gas, and auto stocks were particularly hard hit as investors reacted to the bearish sentiment.
