Micron's 23% Slide From Peak: A Chip Sector Reset, a Chinese Challenger, and a Strike Vote in Taiwan

Micron slid 4.8% to EUR 845.20 as semiconductor stocks sold off on AI spending doubts and CXMT's 4F² DRAM plans; DA Davidson kept a $3,000 target.

Micron Technology shareholders watched the memory-chip maker's stock retreat 4.8% to EUR 845.20 in today's session, extending a decline that has now left the equity 23% below its 52-week high. The pullback was not a Micron-specific event: a broad sell-off swept the semiconductor complex, dragging Nvidia, Broadcom, and Qualcomm down alongside it.

At the root of the sector-wide weakness, according to reporting from Reuters and the Associated Press, are mounting investor doubts about the durability of artificial intelligence spending and fresh questions about the competitive landscape. Those two anxieties collided this week, and memory producers sat squarely at the intersection.

CXMT's 4F² Ambitions Reshape the Supply Picture

The immediate catalyst was news surrounding ChangXin Memory Technologies, the Chinese memory manufacturer working on a denser 4F² DRAM cell design. CXMT is reportedly targeting shipment of DDR5 server products by the end of 2026 — a timeline that, if met with reliable manufacturing yields, would inject additional supply into a segment that has long been a margin engine for incumbents.

That prospect matters because the memory market's recent strength rested heavily on the assumption that AI infrastructure buildouts would absorb every available unit of high-performance memory. Should a credible alternative supplier emerge, the pricing power that established players have enjoyed could come under pressure. The market has a habit of discounting such structural shifts well before they materialize, meaning margin compression could arrive ahead of the actual product launch.

The debate now turns on a single question: can demand from global data centers continue to soak up supply, or are large customers beginning to order more cautiously? If the latter, the pricing framework for advanced chips shifts quickly.

DA Davidson's Luria Stays Bullish With a $3,000 Target

Not everyone reads the sell-off as a warning sign. Roughly a week ago, DA Davidson analyst Gil Luria raised his price target on Micron from $2,100 to $3,000 while reiterating a buy rating. Rosenblatt Securities also lifted its target, moving to $1,900 from $1,500.

The optimistic case rests on the argument that the market still undervalues Micron's technological relevance for complex computing architectures. From this vantage point, sector corrections function as entry opportunities for long-horizon investors, provided the company's technological leadership remains intact. Demand for advanced DRAM solutions, bulls contend, has not gone anywhere.

Taoyuan Union Vote Adds an Operational Wildcard

Layered atop the sector dynamics is a labor dispute at Micron's Taoyuan facility in Taiwan. Unionized workers voted overwhelmingly to authorize a strike, with 1,994 members — 99% of those voting — backing the mandate. The disagreement centers on the company's bonus system.

No strike date has been set. The union has announced a rally for October 19 and has floated the possibility of unannounced work stoppages should negotiations fail. Management said it takes employee concerns seriously and intends to continue the dialogue.

Buyback Authorization Offers a Capital Backstop

On the capital side, Micron's board expanded its share repurchase authorization to $35.16 billion. Buybacks under that resolution become available from December 9, 2026, though the board has made no binding commitment to purchase.

The Technical Line in the Sand

For chart watchers, the near-term picture hinges on whether buyers can reclaim the 50-day moving average of EUR 857.80. With the stock having slipped beneath that level, momentum remains impaired and the market is hunting for a floor. A swift recovery above it would calm nerves; continued skepticism about AI budgets — or further evidence of rapid competitor progress — would risk widening the correction.

The end of 2026 now serves as the overarching checkpoint, when it will become clear whether CXMT's server products genuinely reach market readiness and reshape the global memory cycle.
