Micron's 15% Weekly Slide: AI Jitters, a Chinese DRAM Rival and a Taiwanese Bonus Standoff

Micron Technology shareholders endured a bruising finish to the trading week. The memory chipmaker's stock dropped 5.9% on Friday to close at EUR 781.80, capping a five-day rout that erased 15% of its value as a broad selloff swept through the semiconductor sector.

The retreat widened the gap to the shares' 52-week high of EUR 1,103.80. Market watchers pinned the sector-wide pullback on mounting doubts over whether the massive spending surge tied to artificial intelligence can be sustained — skepticism that hit chipmakers across the board in the final sessions of the week.

A Chinese Challenger Sharpens the Competition Picture

Competitive pressure added to the gloom. The broader withdrawal from memory chip names followed reports of technological strides at Chinese memory producer ChangXin Memory Technologies (CXMT). According to CXMT President Cao Kanyu, the company has made significant progress on a denser 4F² DRAM cell design, and it plans to bring a corresponding DDR5-RDIMM server memory product to market by the end of the year. The announcement stoked fears in the market about intensifying competition for established memory manufacturers such as Micron.

Taiwan's President Steps Into a Bonus Dispute

Separately, labor tensions are simmering at Micron's key manufacturing site in Taoyuan, Taiwan. Reuters reported that President Lai Ching-te on Thursday urged both Micron's management and worker representatives to negotiate in good faith to head off a threatened strike. The dispute centers on bonus payments at the Taoyuan plant. The local union has already secured authorization for strike action, though it has not yet set a concrete date — a timing problem the company's management could do without.

Taiwan is a critical node in the global semiconductor supply chain, and a walkout in Taoyuan would risk costly production delays. The fact that the island's head of state has personally intervened underscores how serious the situation on the ground has become.

Strong Fundamentals Beneath the Selloff

Reading the latest price action as the start of a fundamental downward spiral would be short-sighted. Micron delivered outstanding numbers for the fourth quarter of fiscal 2026 on September 30. Quarterly revenue climbed to $54.23 billion, while adjusted earnings per share reached $33.42.

That earning power is no one-off. Guidance for the first quarter of fiscal 2027 points to continued demand, with management targeting revenue of $61.5 billion, plus or minus $1.5 billion, and adjusted earnings of $38.15 per share. Operationally, the memory specialist is far from crisis mode.

Buybacks and a Bullish Analyst Call

The leadership also has considerable firepower for supporting the share price. A mandatory disclosure dated October 9 revealed that the board authorized a share buyback program totaling $35.16 billion, with purchases under the increase permitted from December 9, 2026. A repurchase volume of that magnitude signals confidence in the company's own balance sheet.

Wall Street has largely stayed optimistic as well. On October 7, D.A. Davidson raised its price target on the stock from $2,100 to $3,000 and reaffirmed its buy rating.

Regulatory filings painted a busier picture behind the scenes. Form 4 submissions to the SEC dated October 13 disclosed a series of transactions by Micron executives and board members — including CEO Sanjay Mehrotra — covering stock awards, the vesting of contractual claims and transactions for tax withholding purposes. The company also published the risk factors chapter of its annual report on Form 10-K for the fourth quarter of fiscal 2026.

The Verdict Hinges on the Negotiating Table

On balance, the upside still appears to outweigh the risks at the current price. The recent pullback already prices in a good deal of geopolitical and sector-specific turbulence. Should management resolve the bonus dispute quickly at the negotiating table, sentiment could calm just as fast. A formal strike resolution, by contrast, would keep the stock under near-term pressure.
