Key Takeaways
Micron Technology Inc. capped a historic 32% weekly rally, its best since 2008, as overwhelming demand for memory chips used in artificial intelligence servers creates a widespread supply shortage.
“Recent headlines point to robust AI infrastructure demand,” BNP Paribas analyst Nick Jones wrote in a research note.
The surge left Micron (MU) up 102.7% year-to-date, far outpacing the broader tech sector. Peer Sandisk (SNDK) also jumped 26% this week. Despite the gains, Micron trades at just 8.6 times forward earnings, a steep discount to the PHLX Semiconductor index average of 25.9.
The rally is underpinned by a severe supply-demand imbalance for high-bandwidth memory (HBM), with customers of chip makers like SK Hynix reportedly offering to directly fund production lines. With HBM supply for 2026 already sold out, the dynamic points to sustained pricing power for memory producers.
Micron sits at the center of the AI buildout, with its HBM3E and HBM4 memory being critical components for high-performance GPUs. Nvidia Corp. has confirmed Micron as a core supplier for its upcoming GeForce RTX 50 Blackwell GPUs, cementing its role in the AI supply chain. This has translated into formidable financial performance. For the second quarter of fiscal 2026, Micron reported revenues of $23.86 billion, a 196% year-over-year increase, while non-GAAP earnings per share surged 682% to $12.20. The company's non-GAAP gross margin expanded to 74.9% from 37.9% in the year-ago quarter.
While the fundamental picture appears strong, a recent regulatory filing shows a notable insider sale. Micron President and CEO Sanjay Mehrotra sold 39,995 shares for a total of $21,450,554 on May 1, 2026. The transactions were executed at prices ranging from $511.91 to $545.39 per share.
The sale was conducted under a Rule 10b5-1 trading plan, which was adopted by Mehrotra on January 30, 2026. These plans allow insiders to sell shares at predetermined times to avoid accusations of trading on non-public information. However, the large size of the sale during a record-setting rally has caught the attention of market participants, adding a layer of context to the stock's recent performance.
