While the broader stock market has spent years fixated on the processors that allow artificial intelligence (AI) to think, a massive rotation is occurring into the hardware required to provide AI with a memory. Approximately one year ago, Western Digital (NASDAQ: WDC) spun off its flash memory business to create SanDisk (NASDAQ: SNDK) as a standalone entity. The market response has been nothing short of historic.
SanDisk has surged approximately 1,500% since listing in early 2025, including a 140% gain in just the last 30 days. As of Feb. 3, 2026, SanDisk stock is trading near all-time highs of $665. Meanwhile, its former parent company, Western Digital, has also seen stellar gains, rising about 350% over the last year to trade in the $280-$290 range.
