Sensex, Nifty, closing market update: Indian benchmark indices closed sharply higher on Thursday, marking a third consecutive session of gains as investors rotated into financial and energy heavyweights amid the expiry of Nifty weekly and monthly derivatives contracts.

The BSE Sensex surged 1,000.36 points, or 1.21 per cent, to finish at 83,755.87, while the NSE Nifty 50 climbed 285.15 points, or 1.13 per cent, ending the day at 25,529.90. The values represent the strongest single-day gains in nearly three weeks, supported by widespread buying in blue-chip counters.

Top Sensex gainers included Adani Ports, Bajaj Finance, Eternal (Zomato), Bharti Airtel, Reliance Industries, and HDFC Bank, while Tech Mahindra, SBI, Sun Pharma, and Trent were among the laggards.

In the broader market, the S&P BSE MidCap index rose 223.86 points, or 0.49 per cent, to 46,330.31, and the S&P BSE SmallCap index advanced 61.79 points, or 0.11 per cent, to 53,959.04.

Sectoral performance was led by banking, with the Nifty Bank index hitting an intraday record high of 57,076.95, driven by Axis Bank, HDFC Bank, and ICICI Bank. The Nifty Oil & Gas index added 0.88 per cent, and the Nifty Metal index gained 0.46 per cent, further supporting the bullish trend.

Not all sectors participated: the Nifty Realty index fell 1.8 per cent, while the Nifty PSU Bank index dropped 0.52 per cent.

Thursday’s rally unfolded amid muted volatility despite the F&O expiry, suggesting that much of the associated positioning had already been absorbed earlier in the week. With financials and energy leading the advance and broader market breadth remaining firm, investor sentiment remains upbeat as the new derivatives cycle begins.
