Benchmark indices Sensex and Nifty significantly fell from their highs to trade in deep red on October 23 due to various reasons, including FII selling and rising crude prices.
At 10:59 am, the Sensex was down 627.39 points or 0.86% at 72,622.00, and the Nifty was down 249.40 points or 1.1% at 22,438.25. About 519 shares advanced, 3,245 shares declined, and 140 shares were unchanged. Sensex fell 1,100 points from day's high while Nifty was trading below 22,450-mark.
Mahindra & Mahindra, Titan Co., and Hindalco Industries added significant downside pressure on the 50-stock index while IT giants Infosys, Tata Consultancy Services, and Reliance Industries lent support. TCS rose 3% and was the top gainer in the key index while Hindalco Industries fell over 2% to be the worst-hit stock. Ahead of reporting its earnings for the September quarter, Infosys rose around 2.5%.
While the Nifty Smallcap 100 fell a touch over 3%, mid-cap trackers lost around 1.4% each. On the National Stock Exchange, the advance-decline ratio leaned sharply towards the laggards.
On 22nd October 2026, FIIs remained net sellers, offloading equities worth Rs 3,459 crore, while DIIs provided buying support with net purchases of Rs 2,891 crore. However, domestic institutional buying only partially offset the sustained selling pressure from foreign investors.
