2. Why Are Bears Dominating? 6 Key Reasons

Market experts and analysts have identified six primary factors driving the current sell-off:

• 1. Crude oil surge: Brent crude traded at $91.46 per barrel, up 0.63%, raising inflationary concerns for India.[reference:5] Higher oil prices strain fiscal deficit, weaken the rupee, and prompt foreign capital outflows.[reference:6]
• 2. US-Iran geopolitical tensions: The temporary US-Iran ceasefire expired, with Iran warning of a “timely and precise” attack if diplomacy fails.[reference:7] President Trump ruled out an extension of the ceasefire arrangement.[reference:8]
• 3. Rising US Treasury yields: The US 10-year bond yield rose to 4.73%, reducing the appeal of emerging-market investments.[reference:9]
• 4. FII selling: Foreign Institutional Investors turned net sellers in the Indian stock market, with FIIs selling ₹2,535 crore of Indian stocks.[reference:10][reference:11]
• 5. IT sector weakness: The Nifty IT index fell 1.93%, ending as the top loser among sectoral indices.[reference:12] Infosys, Wipro, and HCL Technologies fell 2% each.[reference:13]
• 6. Rupee depreciation: The rupee depreciated by 7 paise to 95.68 against the US dollar.[reference:14]

Vinod Nair, Head of Research at Geojit Investments, noted: “Crude oil remained the primary drag on market sentiment, while rising U.S. bond yields and weak global cues prolonged the risk-off trend in Indian equities.”[reference:15]

3. Sectoral Performance: IT Bleeds, Auto Holds Strong

Realty stocks were among the top midcap losers, with Oberoi and Lodha among the top decliners.[reference:16] On the other hand, Tube Investments gained 8% following a positive outlook from brokerages, while Bosch extended its gaining streak and is up 19% this month so far.[reference:17]

Among individual stocks, Indo-MIM surged 10% on strong first-quarter results, with the stock almost doubling from its issue price.[reference:18]
