Sensex, Nifty, Share Prices: In a volatile trading session, Indian equity markets witnessed a sharp decline on Friday, with the benchmark indices closing significantly lower. The BSE Sensex plunged 808.65 points or 0.98 per cent to end at 81,688.45, while the Nifty 50 fell 200.25 points or 0.79 per cent to close at 25,049.85. The sell-off was primarily attributed to rising geopolitical tensions in the Middle East, which pushed crude oil prices higher and dampened investor sentiment. Brent crude surged by $5.5 per barrel to $78, raising concerns about inflationary pressures and potential delays in interest rate cuts. Market breadth remained negative, with 2,387 stocks declining against 1,563 advances on the BSE. The mid-cap and small-cap indices outperformed large-caps, losing 3.1 per cent and 1.8 per cent respectively over the past week, compared to the 4.2 per cent decline in the Nifty-50 and Sensex.
