Mumbai, April 24 -- Stock markets fell for the second consecutive day on Thursday, with the benchmark Sensex tumbling 852.49 points, as crude oil prices breached the $100 per barrel mark again amid stalled US-Iran negotiations. Sustained foreign fund outflows, along with a weak trend in Asian and European equities, also unnerved investors. The 30-share BSE Sensex tumbled 852.49 points, or 1.09%, to settle at 77,664. During the day, it fell 942.31 points, or 1.20%, to 77,574.18. A total of 2,517 stocks declined, while 1,762 advanced and 170 remained unchanged on the BSE. The 50-share NSE Nifty slipped 205.05 points, or 0.84%, to end at 24,173.05. "Indian equity markets extended their decline, turning decisively negative as geopolitical tensions intensified. Sentiment deteriorated following stalled Iran peace talks despite US President Donald Trump announcing an indefinite ceasefire extension, which lacked clear confirmation from Iran. "Escalating concerns around tightening control over the Strait of Hormuz and the continuation of the US naval blockade pushed the Middle East situation back to a critical juncture," Ponmudi R., CEO of Enrich Money, an online trading and wealth tech firm, said.From the Sensex pack, Trent, Bajaj Finserv, Tech Mahindra, Mahindra & Mahindra, Infosys and HDFC Bank were among the major laggards. In contrast, Adani Ports, Larsen & Toubro, Sun Pharma, Bharti Airtel and Bharat Electronics were the winners. Brent crude, the global oil benchmark, traded 1.89% higher at $103.8 per barrel. "Indian markets extended their losing streak, with the Nifty witnessing back-to-back bearish sessions and correcting over 400 points across the last two trading days. The price action reflects a clear shift in market tone-from resilience to risk aversion-as global uncertainties intensify and domestic triggers fail to provide immediate support," Hariprasad K., Research Analyst and founder, Livelong Wealth, said. The BSE MidCap Select index declined 0.39%, and the SmallCap Select index dipped 0.34%. On the sectoral front, PSU Bank dropped 2.36%, Auto (2.27%), Realty (1.91%), Consumer Discretionary (1.71%), Consumer Durables (1.63%) and Bankex (1.46%). On the other hand, Healthcare jumped 1.66%, Capital Goods (0.40%), Power (0.40%) and Industrials (0.11%). "Concerns surrounding disruptions in the Strait of Hormuz have significantly dented investor confidence, introducing a fresh layer of uncertainty into global markets. This has directly translated into a spike in crude oil prices. For an import-dependent economy like India, this creates a dual pressure, rising inflation expectations and stress on corporate margins," Hariprasad said. Foreign Institutional Investors (FIIs) offloaded equities worth Rs.2,078.36 crore on Wednesday, per exchange data. The rupee extended its losing streak for the fourth consecutive session, settling 33 paise lower at 94.11 (provisional) on Thursday. In Asian markets, South Korea's benchmark Kospi ended higher, while Japan's Nikkei 225 index, Shanghai's SSE Composite index and Hong Kong's Hang Seng index settled lower. Markets in Europe were quoting lower in mid-session deals. "Domestic equities witnessed a broad-based decline, as elevated crude prices above $100 per barrel, amid the impasse in US-Iran negotiations, continued to weigh on sentiment. The risk-off mood was further intensified by weak global cues, persistent FII outflows, and a depreciating rupee alongside higher US Treasury yields," Vinod Nair, Head of Research, Geojit Investments Ltd, said....
