Micron Holds $861 as the Broadcom AI-Capex Scare Drags Memory Off Its High

The Catalyst That Won't Let Go

This is the same fire, now in its third session. It started when Broadcom posted record Q2 revenue of $22.2 billion but guided Q3 AI chip sales to roughly $16 billion against a $17.2 billion consensus — and pointedly declined to raise its full-year AI forecast. CEO Hock Tan added that Broadcom will now sell custom AI chips only rather than full systems. Because Broadcom is the foundry-to-silicon partner for the largest AI buildouts, its guidance functions as a demand gauge for the whole hardware stack. When that gauge wobbled, the single-day drop erased about $350 billion in market value and dragged HBM-levered names with it. Micron had no news of its own — it just sits at the most cyclical, highest-beta corner of the AI memory trade, so it took the brunt.

No Cushion After a Parabolic Run

The reason an 11% leg lands this hard is the run that preceded it. Micron ripped roughly 93% in a single month, closing at an all-time high of $1,079.57 on June 3, fueled by a UBS price-target hike from $535 to a Street-high $1,625 and a genuine HBM shortage — Micron has sold out its entire 2026 HBM4 capacity and is filling only 50–65% of key customers' demand. That's a real fundamental story, but at $1,079 it was priced for perfection. From that close to today's $861.70 is a ~20% drawdown in three sessions. When positioning is that crowded and the chart is that vertical, you don't need bad company news to unwind it — you just need the marginal buyer to hesitate, which is exactly what Broadcom delivered.

The Macro Tap on the Shoulder

Friday added a second, smaller weight. The May employment report showed 172,000 nonfarm payrolls added against an 80,000 estimate, reviving fears the Fed leans hawkish into year-end — a direct headwind for long-duration, high-multiple tech. Notably, even an unambiguous positive landed flat: Nvidia certified Micron's HBM chips for its AI accelerators, but that was already priced into the stock. That's the tell of an overextended name — good news does nothing, and any wobble gets sold. Worth flagging too: insider filings show 65 discretionary transactions from March through June, all sales, with zero open-market buys.

What June 24 Settles

The argument resolves on June 24, when Micron reports fiscal Q3. Guidance already points to roughly $33.5 billion in revenue and ~81% gross margin — numbers that, if confirmed, hand the bulls a memory super-cycle and make this pullback a dip. If management hedges on pricing or 2027 HBM demand, it confirms the bear read that AI memory capex is plateauing right as the stock went parabolic. Until then, MU trades as a high-beta proxy for the entire AI capex debate, and the perp will move on Broadcom-adjacent and macro headlines more than anything Micron-specific. The June 3 high at $1,079.57 and the broad analyst average near $828 frame the range the tape is currently arguing over.
