Micron Sinks 6%, Western Digital Falls 5% but SanDisk Holds Steady - 24/7 Wall St.

At midday Tuesday, semiconductor and storage stocks were under pressure, but not all names were affected equally. Micron Technology (MU) shares dropped 6%, and Western Digital (WDC) fell 5%, while San... Read original →

The divergence in memory stocks reflects a strategic realignment, not just profit-taking. Micron and Western Digital’s pullback stems from stretched valuations amid slowing AI server build-outs, while SanDisk’s resilience signals a market shift from commodity NAND to high-margin enterprise SSDs—evidenced by its 645% YoY datacenter revenue surge. Technically, sub-3nm scaling intensifies EUV dependency, limiting Micron’s NAND agility despite DRAM leadership; SanDisk, leveraging Kioxia’s Japan-based mature nodes, secures supply amid geopolitical friction. Regulatory tightening on China exports forces all three to reconfigure Taiwan, China and Southeast Asian fabs as compliance silos, raising costs. Over the next 12 months, HDDs will linger in cold storage, but AI clusters are irreversibly migrating to NVMe SSDs. If SanDisk sustains >78% gross margins and deepens integration with NVIDIA’s GPU stack, it could become the AI hardware rotation’s new cornerstone.
