The memory-chip giant closed the week with a painful 13% loss, despite Friday’s modest relief rally. Micron Technology shares ended at €746.30, nearly flat on the day but nursing deep wounds from a Wednesday that saw the stock plunge 7% after a double dose of bad news. The weekly decline stands at 32.39% below the 52-week high of €1,103.80 reached on June 25, yet any glance beyond the past month reveals a stock that is still up 664% over twelve months and has rallied 723% from its August 2025 low of €90.64.
The immediate trigger for the midweek sell-off was the announcement from Chinese rival ChangXin Memory Technologies (CXMT) of plans for an initial public offering on Shanghai’s STAR Market worth $8.5 billion. Analysts estimate CXMT’s market valuation at $85.5 billion, and investors immediately began pricing in the risk of future overcapacity and a potential price war in the memory space. That fear was compounded by reports that Washington is considering fresh export restrictions on high-performance memory chips.
Yet the fundamentals, taken in isolation, tell a story of unprecedented strength. Micron just delivered the strongest quarter in its history for the third fiscal quarter of 2026, with revenue of $41.46 billion — a 345.7% jump from the prior year and 17.6% above analyst expectations. The GAAP gross margin rocketed from 37.7% to a staggering 84.6%. The company has signed sixteen strategic customer agreements, including four hyperscalers, several mid-tier tech firms, and nine automotive suppliers, with contracts running through to 2030. During the week, Micron added seven Tier-1 auto giants to that list, securing fixed-volume, take-or-pay commitments that provide multi-year revenue visibility. Total customer deposits and letters of credit now stand at $22 billion — a cushion the memory industry has never seen in earlier cycles.
That contractual backbone explains why some of the selling feels overdone. Micron had already sold out its entire available HBM capacity through calendar 2026 before the stock began its descent. According to IDC, Samsung, SK Hynix, and Micron together control more than 95% of global DRAM production, and all three have shifted fab capacity aggressively toward HBM, where revenue per wafer is three to five times that of standard DDR5. Micron itself stated that tight supply conditions are likely to persist beyond 2026.
Should investors sell immediately? Or is it worth buying Micron?
So why is the stock tumbling? A 14-day RSI of 40.9 suggests neutral to slightly oversold conditions, but the annualized volatility has topped 100%. Part of the answer is simple profit-taking after a parabolic rally. But there are also new, concrete risks. The CXMT IPO is one. Another is a class-action lawsuit filed on June 25, accusing Micron, Samsung, and SK Hynix of antitrust violations by diverting production capacity to high-margin HBM and artificially constraining standard DRAM supply. And then there is Michael Burry. The investor famous for his prescient bet against the housing market disclosed a short position opened at €1,051.87, describing the rally as fueled by “AI hype and FOMO, not fundamentals.” A headline from an investor of his caliber was enough to spark de-risking in a stock that had run parabolic.
Wall Street remains broadly constructive. The average analyst price target stands at $1,299.51, implying about 74% upside from current levels, though the range — from $190 to $2,000 — reflects deep uncertainty about near-term direction. Jim Cramer issued a stark warning to investors with leveraged positions, predicting massive losses before the weekend.
The central tension for Micron shareholders is whether this 32% retreat from the June peak is a healthy pause within a structural super-cycle or the first crack in a narrative built on exceptionally optimistic assumptions. The company’s record margins, $22 billion in contractual deposits, and sold-out HBM pipeline through 2026 argue strongly for the former interpretation, but the market’s attention is momentarily fixed on a new Chinese rival, a prominent short seller, and the prospect of tighter export controls. The coming trading sessions — especially any news on US export rules — will offer early clues about which story prevails.
