Micron Slides Under $884 as the Broadcom AI-Memory Unwind Hits a Third Session

The Broadcom Domino

This is not a Micron problem — it's a basket problem. The selloff started Wednesday when Broadcom guided Q3 AI chip sales to roughly $16 billion against a $17.2 billion consensus and, more importantly, declined to raise its 2026 AI semiconductor forecast. For a market that had priced in an ever-steeper AI capex ramp, a held-flat number reads as a downgrade. The reaction was indiscriminate: Broadcom, Micron, ARM, Marvell and Intel all sank together, and by Friday Micron was leading the S&P 500 lower with a double-digit intraday drop alongside roughly 11% declines in Intel and SanDisk. The HIP-3 perp print of -9.84% over 24 hours to $883.80 captures the second-derivative pain: a name with no bad news of its own getting marked down on someone else's guidance.

Good News That Didn't Matter

Here's the tell that this is sentiment, not fundamentals. In the same window the stock was being dumped, Micron confirmed it had entered high-volume production of HBM4 designed for Nvidia's Vera Rubin platform, delivering over 2.8 TB/s of bandwidth — a 2.3x improvement over HBM3E. Jensen Huang publicly certified Micron alongside Samsung and SK Hynix as a Vera Rubin HBM4 supplier. On any normal tape that's a green light. Instead the market shrugged — partly because Micron is the junior supplier in that group, with analysts estimating SK Hynix at 60-70% of Vera Rubin HBM4 volume and Micron taking the remainder. When confirmed design wins can't put a floor under the stock, the move is about positioning, not the business.

No Cushion Left

The reason this hurts is that the run into it was vertical. Micron was up roughly 93% in a single month and 266% year-to-date, printing near $1,053 just three sessions before this $883.80 mark — call it a ~16% drawdown off the top in days. That's the math of a parabola with no support beneath it: the consensus analyst target sat near $726, *below* the pre-selloff price, and insider activity over the run showed dozens of discretionary sales with zero open-market buys. A name that has tripled on the year doesn't need a fresh negative catalyst to fall; it just needs the marginal buyer to blink, and Broadcom gave everyone the excuse. The next hard catalyst is fiscal Q3 earnings on June 24 — until then the perp is trading pure flow and the memory-cycle-has-peaked debate.
