Tech stocks trigger the S&P 500's worst day since October, rates-cut hopes fade fast

The U.S. stock market logged its worst day since October on Friday, and it wasn’t a slow leak. The S&P 500 dropped 2.6%, and the Nasdaq sank 4.2%, as a sell-off in big technology companies spilled into the broader index. The move mattered because it came right on the heels of a market run that had powered the S&P 500 through a series of records over the past two months. When the leaders stumble this hard, “risk off” stops being a vibe and becomes a mechanism.

Tech names set the tone in a way that’s hard to ignore. Nvidia fell 6.2%, Broadcom dropped 7.9%, and Micron Technology slid 13.3%, the biggest loss among S&P 500 stocks. Meta also got hit, falling 5.5% after a published report said the social media company may seek a new stock offering to raise funds for spending on AI infrastructure. Even with stocks inside the S&P 500 not far from evenly split between gainers and losers, the largest tech companies carry enough weight and valuation gravity to pull the index.

Underneath the equity tape, the rate story got louder, and fast. Bond yields jumped after a Labor Department report showed the U.S. added 172,000 jobs in May, surprising markets and strengthening the case that the Federal Reserve will not be in “cut” mode soon. The same dynamic played through the Treasury curve: the 10-year Treasury yield rose to 4.54% from 4.50% just before the report, while the 2-year Treasury yield climbed to 4.16% from 4.04% prior to the release. For decision-makers watching the cost of capital, those are not trivia moves. They signal the market is repricing future policy, and that repricing tends to hit long-duration assets hardest, including high-multiple growth tech.

The market’s framing for Fed policy is now grim on cuts. Policymakers were expected to keep interest rates steady at the June 16-17 meeting, despite pressure from President Donald Trump to lower borrowing costs. But longer-term, the market sees a better than 60% chance the Fed pushes rates higher by the end of the year, according to CME FedWatch, and “little to no chance of a cut.” In a research note, Ronald Temple, chief market strategist at Lazard, said: “Any hopes of a Fed rate cut have effectively been eliminated with this morning’s strong jobs report.” Whether you manage a portfolio, a balance sheet, or a board agenda, that sentence is the core of the day.

This is also happening in a macro environment where inflation pressure is not fully gone. Prices were already ticking higher from the impact of tariffs, and the U.S. war with Iran has essentially blocked crude oil shipments from moving through the Strait of Hormuz. That showed up in oil prices quickly: Brent crude fell 2% to settle at $93.09, down from a roughly $70 per barrel level earlier. The surge in energy costs then fed into broader fuel costs, contributing to inflation risk and threatening to slow growth. A measure of inflation preferred by the Fed showed prices rose 3.8% overall in April, marking the biggest increase in two years. In other words, even if Wall Street wanted the Fed to cut, the background math has been fighting that instinct.

Corporate earnings were supposed to stabilize things, and for a while they did. Wall Street had been anticipating negotiations to end the war would eventually succeed, and most reports from companies had been surprisingly good, helping the market’s record run. With earnings now in the background, the focus is shifting to valuation and affordability. Analysts have been warning that the tech companies benefiting from interest in artificial intelligence may have become too expensive, and that could mean a slowdown for a market that has posted a solid gain in 2026, with the S&P 500 up 7.9% for the year.

In the meantime, investors also had to process “real economy” pressure signals coming in alongside earnings. Lululemon slumped 8.6% after trimming its revenue and profit forecasts. That’s not an AI story, but it’s the kind of guidance reset that tends to matter when financing costs rise and consumers feel squeezed. All told, the S&P 500 fell 200.57 points to 7,383.74 on Friday. The Dow dropped 695.15 points to 50,866.78, and the Nasdaq lost 1,121.53 points to close at 25,709.43. Markets were mixed in Europe after markets in Asia fell, underscoring that this was not a uniquely U.S. phenomenon.

For executives and boards, the second-order implication is simple: when markets lose faith in the timing of rate cuts, you do not just see stock volatility. You see re-tuning across capital plans, risk budgets, and expectations about fundraising windows. If your company is in the long-duration growth bucket, or depends on cheap financing assumptions, this kind of day is an early warning system. And if you’re a tech leader with expensive valuation multiples, it’s also a reminder that the “AI winners” narrative can reverse just as quickly as the rates narrative turns against you.
