Another issue weighing on sentiment is the upcoming initial public offering of Chinese memory chipmaker ChangXin Memory Technologies (CXMT), which is expected to rank among Asia’s largest listings this year. While CXMT still trails industry leaders in advanced AI memory products, its planned IPO could provide billions of dollars to expand production and invest in new technologies, adding to uncertainty about the industry’s long-term competitive landscape.

The decline arrived after a strong run for Micron, which has benefited from booming demand for high-bandwidth memory used in AI servers. Although the shares have fallen about 35% from their June peak, they remain up nearly 223% for the year.

Many analysts still believe demand from hyperscale customers will support healthy results well into next year. However, one investor, known by the pseudonym Passage Research, believes the market has become far too optimistic about where Micron’s business is heading over the longer term.

“There is a lot of noise and a lot of chatter about whether Micron off the dip is a buying opportunity,” the investor wrote. “I believe that Micron represents a generational short opportunity and that the stock could experience material downside.”
