From Iran War Panic to New Peaks: How U.S. Indexes Rallied Right Through the Fear

The article explains why U.S. equity indexes, led by the S&P 500, rallied to new highs despite a short-lived panic over the 2026 Iran conflict and surging oil prices. Investors appear to be looking past a temporary energy shock—oil briefly doubled to about $120/barrel—because the market is dominated by AI-driven technology and semiconductors (notably Nvidia and Intel), which are less exposed to oil-driven input-cost shocks. Wall Street forward-looking expectations, plus a ceasefire and manageable shipping disruptions, helped stocks recover; J.P. Morgan warned that sustained $110 oil could shave S&P 500 earnings by 2–5% in 2026. The piece concludes that quality, AI-exposed stocks are the focus for long-term investors even if oil volatility persists.
