U.S. Stocks retreated on Thursday as oil prices surged above $107 a barrel amid escalating tensions in the Strait of Hormuz, halting a weeks-long rally that had pushed major indices to record highs.
The S&P 500 fell 0.4%, the Dow Jones Industrial Average dropped 179 points (0.4%), and the Nasdaq composite declined 0.9% from its own record level. The pullback followed mixed earnings reports from major corporations, with technology and software stocks bearing the brunt of the selloff.
Technology stocks faced particular pressure as the Technology Select Sector SPDR ETF (XLK) appeared poised to end its 16-day winning streak, trailing all ten of its sector peers. In contrast, the iShares Semiconductor ETF (SOXX) continued its strength, hitting its 12th consecutive intraday high and on track for a 17th straight daily gain.
Tesla contributed to the downturn despite reporting better-than-expected quarterly results, falling 3.6% as investors focused on CEO Elon Musk’s warning of a significant increase in capital expenditures for factory expansion to produce robots and other products. Software company ServiceNow dropped even more sharply, declining 17.7% after matching earnings expectations, as concerns grew that AI-powered competitors could undermine its business model.
In the energy sector, Brent crude for June delivery rose 3.1% to settle at $105.07, briefly exceeding $107 per barrel before pulling back. The more widely traded July contract settled at $99.35 after reaching as high as $101. The spike followed heightened uncertainty over maritime traffic in the Strait of Hormuz, where a ceasefire remains in place between the U.S. And Iran but commercial tankers face obstruction.

Why did software stocks fall despite solid earnings?
Investors looked beyond current profitability to future competitive threats, particularly from AI-driven alternatives that could erode market share for established software providers like ServiceNow, even when quarterly results met expectations.

How did oil prices affect different sectors?
Rising crude prices increased operating costs for airlines, yet American Airlines benefited from strong demand while Southwest underperformed, showing that pricing power and operational efficiency can offset fuel cost pressures in the transportation sector.
