Stock markets declined for the third day on Monday, with benchmark indices Sensex and Nifty tumbling nearly 1 per cent following heavy selling in Kotak Mahindra Bank and uncertainty related to the India-US trade deal.

The 30-share BSE Sensex tanked 572.07 points or 0.70 per cent to settle at 80,891.02. During the day, it slumped 686.65 points or 0.84 per cent to 80,776.44.
The 50-share NSE Nifty declined 156.10 points or 0.63 per cent to 24,680.90.

From the Sensex firms, Kotak Mahindra Bank tumbled 7.31 per cent after the company reported a consolidated net profit of Rs 4,472 crore for the June quarter, and flagged stress on the retail commercial vehicle portfolio due to adverse macroeconomic conditions.
