Broadcom Just Broke the AI Trade

Broadcom dropped nearly 14% in after-hours trading after reporting second-quarter revenue below expectations. That single print did what three months of geopolitical chaos, spiking oil, and rising yields couldn't: it broke the tech rally that's carried the S&P 500 up 16% since April.

The market is finally pricing in that AI chip demand isn't infinite, and the rotation happening this morning is the tell. The S&P 500 declined 0.14% and the Nasdaq dropped 0.76%, while the Dow rose 1.08% as money fled semiconductors and piled into industrials and defensives. Investors shifted away from tech into blue-chip and defensive stocks as news of a ceasefire and cooling energy prices pumped the Dow.

This isn't a one-day blip. Broadcom's CEO did not raise the company's full-year target of $100 billion in AI chips, and the stock is down 13% in premarket. When the poster child for AI infrastructure buildout refuses to lift guidance three months into the year, it's a signal that either demand is softening or visibility is gone. Neither is bullish at 42 times earnings.

The concentration risk everyone warned about just became concentration pain. Intel, AMD, Palantir, Qualcomm, and Arm Holdings posted notable losses in the futures session, spreading the damage across the entire semiconductor complex. A small cohort of AI names accounts for over 40% of the year-to-date revision in S&P 2026 earnings, and when those names stumble, the index has no cushion.

The S&P 500 was up more than 16% over April and May, a magnitude that's only happened in four other instances since World War II, and the last time outside a recession was before the 1987 crash. The Shiller P/E ratio currently stands at 42.53 — its second-highest point since the 1999 high of 43.21, right before the dot-com crash. Those aren't scare tactics; they're math. And math works until it doesn't, then it works again very quickly.

The desk has seen this movie. A narrow rally driven by a single theme—dot-com, housing, anything-with-AI-in-the-name—runs until one of the leaders breaks ranks. Broadcom just did. The question isn't whether the AI thesis is real; it's whether the market priced in a decade of growth in six months and left no margin for a single quarter of disappointment. Today's price action suggests yes.

• Oil relief rally fading: WTI is down $3.19 at $92.83, taking pressure off inflation expectations and giving the Dow room to run while tech resets.
• Valuation ceiling hit: Evercore's year-end S&P 500 target of 7,750 implies only 2% upside from current levels — not enough to justify tech's risk premium.
• Sector dispersion widening: The Nasdaq-Dow spread of 185 basis points today is the widest since the March rotation, signaling smart money is hedging concentration.
• Warsh meeting in two weeks: The next FOMC meeting is June 16-17, the first under new Fed Chair Kevin Warsh, with rates held at 3.5-3.75% and no cuts priced for 2026.
