Micron Technology (NASDAQ: MU) delivered a painful month for late buyers, with the stock falling more than 20% between July 1 and July 31.
As a result, a $1,000 investment made at the start of the month would now be worth about $797.
Micron stock closed at $1,032 on July 1 and finished July 31 at $823, representing a decline of approximately 20.25% over the month.
Based on that move, a $1,000 investment made at the start of July would have lost roughly $203, leaving investors with about $797 by month-end.
The decline follows a historic rally that transformed Micron into one of the biggest beneficiaries of the artificial intelligence boom.
The company surged to record highs after reporting fiscal third-quarter 2026 results on June 24. Revenue climbed to $41.46 billion, up 346% year over year, while adjusted earnings per share reached $25.11, comfortably ahead of Wall Street expectations.
Micron’s profitability also reached unprecedented levels. Gross margin expanded to approximately 84.6%, up from 37.7% a year earlier, driven by soaring demand for high-bandwidth memory (HBM), DRAM, and NAND products used in AI infrastructure.
Following the earnings report, Micron stock briefly traded near $1,255, marking an all-time high before retreating throughout July.
Despite record earnings and bullish guidance, investors took profits after the stock’s rapid advance.
Meanwhile, the broader technology sector experienced increased volatility during July, weighing on several AI-linked names. Concerns about future AI spending growth and elevated expectations following Micron’s explosive rally added to the selling pressure.
The weakness culminated on July 31, when Micron shares fell nearly 6% in a single session.
Micron’s bullish run
Even after the recent correction, Micron remains one of the market’s strongest long-term performers, having gained several hundred percent over the past year while maintaining a market capitalization approaching $1 trillion.
Although Micron stock performance disappointed investors over the past month, the company’s underlying fundamentals remain exceptionally strong.
The memory maker guided for fiscal fourth-quarter revenue of approximately $50 billion, significantly above analyst expectations. Adjusted earnings per share are projected to reach roughly $31, while gross margin is expected to approach 86%.
At the same time, demand for AI memory products continues to outpace supply. Micron has indicated that its HBM production for 2026 is fully sold out, with portions of 2027 capacity already committed.
The company has also secured 16 strategic customer agreements backed by approximately $22 billion in customer deposits and more than $100 billion in minimum revenue commitments, providing greater earnings visibility than the memory industry has historically enjoyed.
Although investors who bought at the beginning of July are sitting on losses, Wall Street continues to view Micron favorably.
