Micron's HBM4 Is Fully Booked, Yet Technicals Warn the Party May Be Overdone
01.06.2026 - 19:31:46 | boerse-global.de
Micron shares blasted to a fresh all-time high on Monday, climbing roughly 7% to €891.60, as the memory giant confirmed that its entire HBM4 production capacity is spoken for through the end of 2026. The rally has been nothing short of extraordinary — the stock has more than tripled since January and gained over 900% on a 12-month basis, pushing its market capitalization past $1 trillion. Yet beneath the euphoria, a chorus of technical and valuation signals is urging caution.
Chief executive Sanjay Mehrotra provided the headline catalyst, quantifying a stark supply-demand mismatch: Micron can currently fulfill only 50% to 65% of medium-term customer inquiries. The driver is an unrelenting build-out of AI infrastructure among hyperscale cloud providers, which have shifted from quarterly or annual purchase agreements to multi-year binding commitments. That shift has handed Micron revenue visibility stretching to 2028 — a radical departure from the boom-and-bust cycles that have historically defined the memory industry.
The bullish backdrop was reinforced by developments at the Computex trade show in Taipei, where Nvidia CEO Jensen Huang unveiled the "RTX Spark Superchip," an AI processor for PCs and laptops developed jointly with Microsoft. Micron supplies the DRAM and HBM for that chip and is widely viewed by analysts as one of the chief beneficiaries of the upcoming hardware upgrade cycle. The company has already begun HBM4 production for Nvidia's forthcoming "Vera Rubin" architecture.
The market's response has been an aggressive round of price-target upgrades. UBS lifted its target to $1,625, citing sustained pricing power, while Susquehanna raised its target to $1,750. Despite the recent share-price surge, the forward price-to-earnings ratio stands at roughly 16 — below the multiples assigned to other AI-chip peers. Some analysts argue the market is underestimating a structural transformation: Micron is evolving from a cyclical commodity producer into a growth company with durable competitive advantages.
Should investors sell immediately? Or is it worth buying Micron?
But on the other side of the ledger, the technical picture looks stretched. The relative strength index has pierced 90, a level that historically signals extreme overbought conditions. The stock now trades nearly 80% above its 50-day moving average and almost 200% above its 200-day moving average — distances that outstrip any precedent in the last five years.
Valuation metrics sourced from a widely followed fair-value model peg the stock's intrinsic worth at roughly $360 per share, implying an overvaluation of almost 170% against Monday's closing price of approximately $971. The trailing price-to-earnings ratio of 46 is more than double the five-year average of 21, suggesting new buyers are paying a hefty premium relative to historical norms. With annualized 30-day volatility approaching 89%, Micron remains one of the most jittery names in the semiconductor space.
The next major catalyst lands on June 24, when Micron reports fiscal third-quarter results. Analysts expect revenue of around $33.9 billion — an increase of more than 260% year-over-year. Management itself has telegraphed record revenue, gross margin, and free cash flow. Capital expenditure on new fabrication plants in the United States and Taiwan is set to exceed $25 billion in 2026.
Micron at a turning point? This analysis reveals what investors need to know now.
For now, the bulls have the narrative — sold-out HBM, multi-year contracts, and a new AI PC cycle — but the technicals are shouting that much of that good news is already priced in. The true test will come when earnings confirm whether the current stock price is a reflection of fundamental substance or simply a market trading on anticipation.
