U.S. Stocks Slip as Oil Prices Surge and Tech Selloff Eases, Healthcare Stocks Rally on Rotation

U.S. equities retreated in Friday’s session as a rebound in oil prices weighed on sentiment and pressure in tech eased only partly after earlier losses. The S&P 500 slipped around 0.2%, adding to Thursday’s more pronounced decline, while investor caution weighed on indices tracking broad U.S. equities. According to press reports, three of every four S&P 500 stocks ended the day lower amid elevated oil prices, now at their highest since March.

Thursday’s market session had already seen sharp weakness, with the S&P 500 tumbling 1.2% and the Nasdaq Composite plunging 2.6%. The tech-heavy Nasdaq’s decline reflected an intense sell-off in technology names that momentarily overpowered strength elsewhere in the market.

Oil Surge Adds Pressure, Treasury Yields Ease Tech Concerns

A spike in crude prices—driven by rising geopolitical tensions and potential supply disruptions—heightened inflation concerns and pressured equities broadly. Brent crude lifted to five-month highs, contributing to the S&P 500’s decline, while a partial relief emerged as Treasury yields eased, providing some breathing room for tech valuations.

Even so, the lingering uncertainties around AI-related spending and mounting capital demands continued to weigh on mega‑cap tech stocks, suppressing short‑term market rebounds.

Sector Rotation: Healthcare Leads Gains

Amid the broader volatility, the healthcare sector stood out, rallying sharply as investors rotated toward defensive value plays. Healthcare outpaced other sectors with gains, supported by strength in key drugmakers including Eli Lilly, UnitedHealth, Merck, Johnson & Johnson and Amgen. Eli Lilly emerged as a major driver, pushing the sector to a record high.

The Dow outperformed, buoyed by these defensive stocks, while tech- and oil-exposed sectors lagged behind. This shift underscored a growing investor preference for stable and earnings-resilient themes amid macro uncertainty.

Why It Matters

The pullback in equities highlights investor sensitivity to commodity‑driven inflation pressures and the fragile footing within AI‑focused technology sectors that have been under strain from funding concerns. At the same time, the healthcare-led rally illustrates a rotation toward safety and value in anticipation of continued macroeconomic headwinds.

Looking ahead, markets are likely to remain volatile as investors weigh the outlook for oil-driven inflation, tech‑sector earnings resilience, and the durability of sector rotation flows. Healthcare names may continue attracting attention as more defensive anchors in a choppy market environment.

That said, any stabilization in energy prices or improvement in tech funding sentiment could quickly reshape sector leadership. For now, the cautious tone prevails, with investors favoring earnings stability over aggressive growth exposure.
