S&P 500 — daily market movers
Macro backdrop
All three major indexes fell. The S&P 500 slipped 0.77%, the Nasdaq 0.92%, and the Dow 0.67%. President Trump's rejection of an Iranian peace proposal reignited Middle East tensions, sending WTI crude sharply higher, while the 10-year Treasury yield climbed to a multi-year high near 5.2%. With Fed officials flagging AI-driven inflation, growth and semiconductor names came under pressure, while healthcare and biotech bucked the trend to lead.

Common Themes
The gainers split along two lines, defensive and thematic. Five healthcare/life-science names - VTRS, ISRG, MTD, WAT and COO - drew safe-haven flows as pharma and biotech led against the down market, while PANW and CRWD reflected a stronger cybersecurity group driven by PANW's upgrade and AI-security catalyst. PSKY (M&A progress) and ODFL (a rate increase) had their own standalone catalysts.

Common Themes
The losers clustered in rate-sensitive, high-multiple growth. Consumer-internet, high-duration names like DASH, CVNA and RDDT were sold as the 10-year yield topped 5.2%; tech and semis such as QCOM, INTC, COHR and META weakened on profit-taking and an AI-hardware pullback (INTC also hurt by Apple distancing itself). BA and NEM fell on geopolitics/oil and weaker gold respectively, while REGN dropped on Eylea competition fears.
Overall read
Money rotated clearly out of rate-sensitive, high-multiple tech and consumer-internet and into defensives such as pharma and life-science tools. Rising Treasury yields and Middle East geopolitical risk were the day's dominant drivers - a classic risk-off rotation rather than a broad, uniform selloff.
