SanDisk's stock soars 4,086% in 15 months, outpacing Nvidia's 9-year AI memory growth.

SanDisk has surged 4,086% since its February 2025 spin-off, achieving in 15 months what Nvidia took nearly nine years to do. This rapid growth is driven by a severe supply shortage in AI memory chips, including NAND flash, DRAM, and HBM, crucial for AI data centers. SanDisk's focus on NAND flash and lean production during downturns positioned it well to benefit from soaring demand and high margins, with revenues and datacenter sales sharply increasing. Despite this, the market still prices memory stocks like cyclical commodities, suggesting potential for further re-rating as AI demand continues to grow.
