U.S. equities drifted into fresh highs on Monday even as crude lurched higher and U.S.–Iran diplomacy frayed. Mega-cap technology and semiconductors absorbed most of the oxygen while energy equities participated in the oil rebound.

Session snapshot

Trading was orderly: gains were narrow at the index level, but leadership under the surface skewed toward chips and select software names. Bond yields took a back seat to geopolitical headlines and positioning ahead of Tuesday’s consumer inflation release.

Oil, Iran, and risk appetite

Crude futures jumped nearly 3% after remarks that the ceasefire framework was under strain and diplomatic gaps remained wide. Brent approached mid-session highs above $105 before settling firmer, while WTI pressed toward $100 intraday. With the Strait of Hormuz still impaired for normal flows, refiners and integrated producers repriced scarcity risk even as broader equities looked past the energy tax on consumers for another session.

Earnings fabric and the inflation calendar

First-quarter results continued to validate elevated estimates across much of the S&P 500, with beats concentrated in technology hardware and internet platforms. Management commentary tilted toward AI-related capex and enterprise spending resilience.

The imminent CPI report loomed large: economists projected an uncomfortable monthly print reflecting passthrough from energy, with core inflation still elevated enough to keep Federal Reserve deliberations nuanced. Derivatives pricing suggested investors expect officials to emphasize patience unless goods disinflation reasserts.

Tape drivers worth tracking

  • Semiconductors: Equipment suppliers and handset-adjacent chipmakers extended leadership as investors rotated behind AI infrastructure demand.
  • Energy: Integrated names and services exporters leveraged crude strength even as macro strategists debated persistence above $100.
  • Macro catalysts: Tuesday inflation data and scheduled diplomacy later in the week framed hedging activity across rate-sensitive sectors.
