Memory chips have quietly taken center stage in the AI boom. For months, the narrative revolved around GPUs and accelerators—until investors realized that the real bottleneck might be the high-bandwidth storage feeding those hungry processors. Micron Technology has ridden that shift to a scorching rally, but the past week delivered a sharp reminder that scarcity premiums come with volatility.
On Friday, the stock slipped 3.55% to €829.00, adding to a 7% intraday drop from the previous session triggered by disappointment elsewhere in the semiconductor sector. Yet even after the pullback, the shares remain up 46.05% over 30 days and have surged 208.18% year to date. The 12-month gain stands at an eye-popping 792.17%, with the stock still 11.69% below its recent all-time high. This is not a quiet recovery—it is a momentum regime that has pushed the market cap to roughly €1.03 trillion.
The catalyst for that momentum is a fundamental re-ranking of what matters in AI. At Computex 2026, Micron explicitly positioned memory and storage as strategic infrastructure for data centers and edge applications. The message resonated: DRAM, NAND, and especially high-bandwidth memory (HBM) are no longer commodity components but constrained assets in the AI buildout. That scarcity narrative has lifted the stock far above its traditional valuation anchors.
Enter Morgan Stanley. Analyst Joseph Moore more than doubled his price target on Micron from $520 to $1,050, citing supply tightness that he expects to persist for two to three years. The note points to DRAM prices surging 40% in the quarter ended May and anticipates another 15% gain in the August quarter. Earnings estimates for 2027 have been revised up by roughly 48%. Additional pricing power looms: HBM contract renegotiations are scheduled for late 2026, and Morgan Stanley sees significant upside there. The “Overweight” rating stays.
Yet the same week that saw that bullish call also brought a notable insider transaction. CEO Sanjay Mehrotra sold approximately 37,400 shares on May 29 at an average price of around $960, netting nearly $36 million. The sale was executed under a pre-arranged trading plan established in January. After the transaction, Mehrotra still holds roughly 387,000 direct shares worth over $370 million. Such sales are routine but inevitably raise eyebrows near a stock’s peak.
Should investors sell immediately? Or is it worth buying Micron?
The broader sector also threw cold water on the rally. Broadcom beat earnings expectations but guided its third-quarter AI chip revenue to $16 billion, below the $17.2 billion analysts had hoped for. That miss triggered a broad sell-off in semiconductor names. Micron closed Thursday at €859.50, down more than 7% intraday. The relative strength index now sits at 70, a level often considered overbought.
The next major test arrives on June 24, when Micron reports results for its fiscal third quarter. Markets will be looking for concrete numbers on HBM revenue and gross margins, which recently stood at 75%. The company’s market capitalization crossed the trillion-dollar threshold in late May, and the earnings report will need to validate that valuation. Some optimists on the Street have lifted their targets as high as $1,750, while the consensus price target of €623.78 sits roughly 25% below the current level—a spread that highlights the gulf between hope and fundamentals.
The dichotomy is striking. On one hand, the scarcity story feels more durable than in past memory cycles. HBM and AI storage do not behave like plain-vanilla DRAM. On the other, the stock has already priced in a great deal of that narrative. The tension between a sector-wide capacity crunch and a stock that trades far above its averages will define Micron’s trajectory. Every sign of normalization—whether from easing supply, weaker demand, or a broader tech correction—would test the premium embedded in the shares.
For now, Micron is less a chip stock and more a wager on the evolving hierarchy of AI infrastructure. Memory has become strategic, and that shift makes the stock both fascinating and fragile. The daily fluctuations matter less than the underlying question: how high can the scarcity premium go before the market demands proof in the numbers?
