Wall Street's record-setting rally came to an abrupt halt as escalating conflict in the Middle East sent oil prices surging and triggered a sharp rotation out of growth stocks and into defensive sectors.
The S&P 500 fell 2.1%, snapping a six-day winning streak, while the tech-heavy Nasdaq Composite dropped 3.2% in its worst session since March. The selloff erased roughly $800 billion in market capitalization, with mega-cap technology names bearing the brunt of the damage.
The catalyst: Iran's strikes on UAE port facilities and commercial shipping in the Strait of Hormuz pushed crude oil above $118 per barrel, raising fears of sustained inflation and forcing investors to reassess valuations for high-multiple growth stocks.
"Higher oil prices are a tax on consumers and a direct hit to corporate margins," said Emily Nakamura, chief market strategist at JPMorgan Asset Management. "When you combine that with already-elevated equity valuations, you get the kind of violent repricing we saw today."
The sector rotation was textbook: energy stocks soared while consumer discretionary and technology names cratered. Exxon Mobil gained 7.8% and ConocoPhillips jumped 9.2% as investors positioned for extended high oil prices. Defense contractors also rallied, with Lockheed Martin up 4.1% and Northrop Grumman adding 5.3%.
On the losing side, the carnage was concentrated in rate-sensitive names. Apple fell 3.8%, Microsoft dropped 4.2%, and tumbled . The logic: higher oil prices typically lead to higher interest rates as central banks combat inflation, and elevated rates compress valuations for long-duration growth stocks.
