On Wednesday, the storage sector showed notable strength against the broader market trend. Western Digital (WDC.US) shares surged more than 5%, while SanDisk (SNDK.US) gained over 3%. Seagate Technology (STX.US) advanced nearly 2%, and Micron Technology (MU.US) rose close to 1%.

Catalyst for the Move

The positive movement follows the latest industry survey from TrendForce, which indicates a significant acceleration in conventional DRAM contract prices for the first quarter of 2026. The report highlights a quarterly increase of approximately 93-98%, driving an estimated 81% quarter-over-quarter growth in overall industry revenue to around $97 billion.

The shift in AI applications from large language model training towards AI inference is noted as a key factor. This transition is prompting cloud service providers to expand their data center focus from AI servers to general-purpose servers. Consequently, the demand for memory products is broadening from high-bandwidth options like HBM3e, LPDDR5X, and high-capacity RDIMMs to include RDIMM products across various capacity specifications.
