Micron Stock (MU) Jumps Today, but This Top Investor Has a Warning for Bulls

Micron (NASDAQ:MU) stock jumped ~8% today as the broader market rallied on news of a ceasefire between the U.S. and Iran, a development that eased geopolitical tensions and triggered a broad relief move across equities. Oil prices fell sharply on expectations that energy supply routes, including the Strait of Hormuz, could reopen, which in turn improved the outlook for inflation and interest rates.

Beyond the day’s rally, the bigger conversation around Micron hasn’t gone away. The stock has long been viewed as a cyclical name, given its role as a supplier of computer memory, a segment historically defined by boom-and-bust cycles. But the industry appears to be going through a seismic change, and that means Micron might need to be assessed in a different light from here on in.

AI-driven demand is driving huge revenue growth and margin expansion. Although the memory chip industry has traditionally been highly cyclical and intensely price-competitive, the current severe supply shortage has allowed manufacturers like Micron to exert unusually strong pricing power. This dynamic was evident in the company’s latest quarterly results, where revenue rose 75% sequentially and 196% year over year to $23.9 billion, far exceeding the guidance of $18.7 billion. Gross margins climbed to 75%, while the balance sheet shifted from $4.8 billion in net debt in the second quarter of 2025 to $6.6 billion in net cash.

Looking forward, the company expects FQ3 revenue of roughly $33.5 billion, implying 260% growth versus the year-ago period and 40% sequential growth.

As all this has been taking place, top investor Julian Lin concedes that he was wrong about Micron and says that this time is “indeed different.”

“Micron has defied expectations, so much so as to cause me to withdraw my prior bearishness,” said the 5-star investor. “It is becoming increasingly clear that the AI story is far from being played out, even if AI companies like MU are delivering unprecedented numbers. MU has seen both growth rates and profit margins turn hyperbolic, leading to a significant windfall for the balance sheet.”

But that begs the question, if Micron’s business is seeing such unprecedented success, and the stock is trading at a “low-single-digit multiple of out-year earnings,” why has Lin not become a fully-fledged bull?

That’s because Lin continues to view Micron’s memory business as structurally similar to another sector – the oil industry. While there has been genuine product innovation, the market still remains driven by supply dynamics, and supply is likely to catch up with demand over time. Competitors like Samsung and SK hynix, alongside Micron, are strongly incentivized to ramp capex to capture demand, which can ultimately pressure pricing, much like what happens when oil supply expands after price spikes.

Although this supply response might take time, the sector’s history of operating margins peaking and then reverting sharply – sometimes to zero or negative levels – suggests cyclicality will remain a persistent overhang. As a result, Lin thinks Micron’s valuation is likely to stay constrained, since cyclical stocks often appear cheapest at low P/E multiples and most expensive at high ones due to earnings volatility.

“I think there’s considerable risk that MU stock stays in a range of 2x to 3x earnings, which would put a lid on the potential upside and make it difficult to justify an outright bullish rating,” Lin summed up, assigning MU shares a Hold (i.e., Neutral) rating.

On Wall Street, 3 analysts are also on the Micron fence, yet with an additional 25 Buys, the stock claims a Strong Buy consensus rating. Based on the $543.13 average price target, shares could trade at a ~34% premium over the next year. (See Micron stock forecast)
