Micron’s shares weakened over October 2–6 even as the company reported record results. The tension is between strong current demand and uncertainty about how long unusually high memory prices and earnings can last. Management expects supply to remain tight through 2028; Morningstar’s more cautious view is that capacity additions could eventually push prices down. The stock’s decline alone does not establish that a peak has arrived—or explain each day’s move.

What happened to Micron shares
Micron closed at $1,074.89 on October 2, $1,063.96 on October 5 and $1,045.56 on October 6. The available price record also showed overnight trading at $1,045.20 late on October 6. Those figures document the slide, but not its precise cause.

The broader debate is visible in the coverage: investors were weighing the company’s strong outlook against the possibility that a cyclical memory boom will eventually cool. Reports also pointed to heavy spending plans as a consideration, despite the positive earnings outlook.

Record results strengthen the bullish case
For the fiscal fourth quarter ended September 3, Micron reported $54.23 billion in revenue, compared with $11.32 billion a year earlier. Fiscal 2026 revenue was about $133.2 billion. The company also guided to $61.5 billion in revenue for its next quarter, according to its earnings-call coverage.

Management said memory and storage supply-demand conditions were expected to be tighter in fiscal 2027 and 2028 than in 2026. More than 75% of fiscal 2027 output had already been committed, while discussions for 2028 were underway. That outlook supports the view that customer demand and constrained supply could sustain strong results in the near term.

Why some investors worry the cycle could turn
Memory chips are cyclical: an eventual increase in supply can put pressure on prices, which can affect earnings. Morningstar lowered its fair-value estimate for Micron from $850 to $700 and retained a two-star rating. Its analyst expects substantial new capacity to pressure memory prices over time, while still describing pricing as strong through 2027.

Morningstar’s October forecast that memory supply could double by 2028—and that earnings could peak around then—is a model, not an observed turning point. Its estimate of $250 per share in 2028 is likewise a projection, not a reported result.

Acer CEO Jason Chen has also questioned how durable the shortage will be as Chinese producers add capacity. That is a warning about the future supply picture, not proof that Micron’s current shortage or earnings have already peaked.

The counterargument: prices may not have peaked yet
Barron’s reported that fears of a cyclical earnings peak were weighing on Micron, while memory prices told a different story. That is a reason not to read the share-price decline as a direct signal that chip prices have turned down. The article’s framing and management’s tight-supply outlook support the near-term bull case, though neither settles what supply and pricing will look like in later years.

What the pullback does—and does not—show
The October decline is consistent with investors looking beyond a record quarter to questions about valuation, spending and the durability of unusually strong memory pricing. But the cited reports do not pin each session’s move on one specific event.

One margin comparison also needs care: the earnings-call coverage reports fiscal 2026 gross margin of 81.1%, up from 41.1% in fiscal 2025. That is an annual comparison; it should not be treated as interchangeable with a trailing-year margin figure.

The key issue is therefore not whether Micron’s latest results were strong—they were—but whether today’s supply constraints and pricing can persist long enough to support future earnings. Management’s outlook and Morningstar’s cycle forecast offer competing views of that timeline; neither makes the peak certain.
