Micron Slides Under $850 as the Broadcom AI-Capex Scare Hits a Third Session

The Broadcom Domino

This is not a Micron-specific story — it's a sector repricing, and Micron happens to be the highest-beta way to express it. Broadcom reported fiscal Q2 after the close on June 3 and guided Q3 AI semiconductor revenue to $16 billion against the $17.2 billion analysts expected. The number itself was still up triple digits year over year, but the market doesn't trade levels — it trades the second derivative. Management held firm on its $100 billion full-year AI forecast rather than raising it, and CEO Hock Tan walked back the plan to ship complete integrated AI systems, pivoting to chips-only for select customers. Broadcom fell more than 15% in a single session and dragged roughly $350 billion in market cap out of the group, hitting AMD, Intel, Marvell, and Micron with it. For a name whose entire bull case is HBM demand from AI accelerators, any hint that hyperscaler capex is plateauing is the worst possible headline.

No Cushion After the Parabola

The depth of Micron's drawdown — leading the S&P 500 lower with a ~13% session the day after printing an all-time high — is a function of positioning, not new bad news about Micron. The stock had run roughly 93% in the prior month into Wednesday's top. When a name goes parabolic on momentum, there's no valuation floor to catch it on the way down; the marginal buyer was a trend-follower, not a value investor. The cruel tell here: Micron landed HBM4 qualification for Nvidia's next platform the same week and the stock still couldn't hold a bid. That's the signature of a sentiment-driven unwind rather than a fundamental one — good company-specific news gets ignored because the entire factor (AI memory) is being de-grossed at once. Raymond James had already flagged the risk of an early peak in the memory-chip cycle, and that thesis now has air cover.

What June 24 Decides

The next real catalyst is binary and dated: Micron reports fiscal Q3 on June 24. Consensus sits near $19.29 in EPS against $1.91 a year ago, on revenue around $33.88 billion versus $9.30 billion — numbers that only make sense if the AI memory cycle is still accelerating. That print is now the referendum on whether the Broadcom guide was a one-off or the first read on a broader demand rollover. Until then, MU is trading the macro AI-capex narrative far more than its own order book, which is exactly the environment where a perp with a deep book and clean two-way flow earns its keep. The $304 million in 24h volume on this market reflects how much positioning is being repriced into a single event window.
