Buying in blue chips, cooling oil triggers mixed action on D-St
Mumbai: Stock market benchmark indices ended on a mixed note on Thursday, with the Sensex climbing 374 points and the Nifty closing flat, drawing support from moderation in crude oil prices and buying in heavyweights Reliance Industries and ICICI Bank.

After starting the session on a positive note, the 30-share BSE Sensex remained in the positive territory throughout the day. It climbed 373.76 points, or 0.48 per cent, to settle at 78,954.76. The 50-share NSE Nifty traded in a narrow range for the day and edged marginally higher by 11.35 points, or 0.05 per cent, to end at 24,636. During the day, the benchmark hit a high of 24,677.05 and a low of 24,604.15.
Since Monday, both the benchmark indices have been facing divergence after stock exchanges introduced a new auction mechanism for shares having futures and options (F&O) contracts. The Closing Auction Session (CAS) in the equity cash segment became operational on Monday, introducing a new auction-based mechanism for determining the closing prices of eligible stocks in a move aimed at making the price discovery process more transparent and robust.
“Indian equity markets ended the session on a mixed note, with the benchmark indices displaying a notable performance divergence even as investor sentiment remained cautiously constructive amid continued optimism over a potential diplomatic resolution to the Middle East conflict,” Hariselvan Radhakrishnan, Founder & CEO of HST Wealth, a Research Analyst firm, said. The Nifty traded within a narrow range and finished largely unchanged, while the Sensex posted a modest gain, supported primarily by strength in a heavyweight constituent, he said.
“Four sessions into the NSE’s Closing Auction Session (CAS), the divergence between the Sensex and the Nifty is increasingly reflecting differences in market liquidity rather than a transitional anomaly. The same 20-minute closing auction continues to produce contrasting outcomes for the two benchmarks because institutional order flow is concentrated more heavily in Nifty constituents than in the Sensex basket. As a result, the Nifty’s closing level remains more sensitive to auction-driven price discovery, while the Sensex has been relatively less affected,” he added.
