The Nasdaq Composite surged to a new all-time intraday high on Wednesday, gaining 1.4% as the S&P 500 rose 0.8% and the Dow Jones Industrial Average climbed 236 points, or 0.5%, following President Donald Trump’s extension of the U.S. Ceasefire with Iran.
The move came shortly after Tuesday’s market close, when Trump cited Iran’s “seriously fractured” government and referenced appeals from Pakistani Prime Minister Shehbaz Sharif and Field Marshal Asim Munir as justification for delaying military action. He directed the military to maintain the blockade while remaining ready to act, stating the ceasefire would continue until Tehran submitted a unified proposal for negotiations.
Despite the diplomatic pause, tensions in the Strait of Hormuz persisted, with Iran’s navy seizing two container ships on Wednesday, underscoring the fragility of the de-escalation. Oil prices reacted sharply, with Brent crude futures surpassing $100 a barrel, reflecting continued market sensitivity to supply risks in the critical waterway.
Yet equity markets appeared to appear beyond the geopolitical strain, buoyed by a strong start to earnings season. Boeing shares rose 5% after reporting a smaller-than-expected first-quarter loss, while GE Vernova jumped 12% on better-than-anticipated revenue. More than 80% of S&P 500 companies that have reported so far have exceeded forecasts, according to FactSet data, reinforcing investor confidence in corporate resilience.
Ben Fulton of WEBs Investments noted the shift in market sentiment, observing that investors are increasingly treating Middle East developments as background noise. “A week ago, I said, ‘The risk was on the upside.’ The market moves so much that now I look and go, ‘No, the risk is on the downside,’” he said in an interview, adding that it’s time to “put it in the rear view mirror” and stay the course.
The rally extended into sector-specific trends highlighted by Yahoo Finance, with the XLK ETF on track for a historic 16th consecutive win and the SOXX semiconductor ETF logging ten straight intraday record highs. Other intraday peaks were seen across the Dow Jones Transportation Average and sector ETFs covering telecom, steel, publishing, and tech hardware, underscoring broad-based strength in U.S. Equities.
Analysts suggest the divergence between persistent geopolitical friction and rising asset prices reflects a growing conviction that U.S. Markets can outperform global peers, supported by domestic earnings momentum and reduced reliance on volatile international developments.
Why did oil prices rise despite the U.S. Extending the ceasefire with Iran?
Oil prices increased as Iran’s navy seized two container ships in the Strait of Hormuz, indicating ongoing tensions in the critical shipping route even amid diplomatic pauses, which markets interpret as a continued risk to global supply chains.

What does the strong earnings performance suggest about market resilience?
With over 80% of reporting S&P 500 companies beating estimates and major industrials like GE Vernova and Boeing exceeding expectations, the data suggests corporate strength is providing a buffer against geopolitical uncertainty, supporting further equity gains.
