Memory and storage stocks jumped again on Tuesday, as investors continue to flock to the space amid the artificial intelligence spending boom.
Micron (MU) shares rose more than 6% in early trading, while Sandisk (SNDK) surged nearly 19%. Western Digital (WDC) and Seagate Technology (STX) saw gains of 7% and 5%, respectively. Over the past year, gains in the aforementioned companies have topped more than 200%, and in the case of Sandisk, more than 600%.
Micron reported its most recent quarterly results and guidance in December that were significantly better-than-expected. As such, a number of Wall Street firms said the company is in the midst of a “supercycle.”
Memory, in particular, high-bandwidth memory, has experienced a shortage as data centers and GPUs gobble up memory for their needs. It was reported earlier this week that Samsung Electronics (SSNLF) and SK hynix (HXSC.F), the two biggest memory makers, are discussing raising prices for server memory by up to 70% in the first quarter.

Last month, Wedbush Securities analyst Matt Bryson said that the surge in demand for memory that started in March 2025 became “even more pronounced in Q4.”
“While we believe Nanya (and to some extent module makers) are benefitting from DDR4 shortages tied to the rapid EOL of this product set, we see strength now as much broader based due to unexpected upticks in demand from [cloud service providers] in the August and September periods which have created shortages throughout DRAM and NAND,” Bryson said. “We now expect trends will continue into 2026, with [cloud service providers] having significantly lifted their outlook for requirements through next year.”
