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:
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.
