Tech Weakness Pulls Stocks Lower

Stocks finished mixed Monday as optimism around tentative U.S.-Iran progress and lower oil prices was outweighed by weakness in megacap technology and AI-linked names. The S&P 500 slipped, the Nasdaq underperformed, and the Dow held slightly higher, while Treasury yields rose and crude retreated after the U.S. authorized limited Iranian oil sales. The day’s tone was less about broad risk-off stress and more about investors reassessing stretched AI expectations, funding needs, and geopolitical uncertainty.

Key Headlines & Market Movers:

• Tech and AI Leaders Drag the Market Lower: Alphabet led losses among megacap technology shares after news that Google DeepMind executive John Jumper is leaving for Anthropic. SpaceX also fell sharply, pressured by concerns around its first investment-grade bond sale and broader questions about heavy AI-related capital spending. The move fed into investor debate over whether AI infrastructure investment can keep generating attractive returns.
• Oil Falls as U.S.-Iran Talks Show Some Progress: Crude prices declined after the U.S. issued a 60-day license allowing Iran to sell oil internationally, easing near-term supply concerns. Markets also took some comfort from reports of progress in negotiations, even though U.S. and Iranian officials offered conflicting descriptions of what had been agreed. Geopolitical risk remains elevated, but the immediate oil-market reaction suggested traders saw reduced odds of a near-term supply shock.

Rates Add Pressure as Investors Watch Inflation: The 10-year Treasury yield moved higher to around 4.50%, adding another headwind for growth stocks and long-duration assets. The rise followed last week’s hawkish Fed tone and comes ahead of Thursday’s May PCE inflation report. Investors are likely to focus on whether inflation data support the Fed’s openness to further rate hikes later this year.

S&P 500 Sector Performance

Looking Ahead

The key near-term catalyst is Thursday’s PCE inflation release, which could shape expectations for the Fed’s next policy moves and influence whether higher yields continue to pressure equities. Markets will also watch whether U.S.-Iran talks can translate into a more durable reduction in geopolitical risk, particularly for oil. Within equities, the AI trade remains central: strong earnings and infrastructure demand are still supportive, but investors appear increasingly sensitive to financing needs, return-on-investment concerns, and signs of crowding in the sector.
