Sandisk Stock Is Up More Than 5,900% Since It Spun Off From Western Digital. Is It Too Late to Buy?

SNDK has rallied nearly 6,000% since spinning off from Western Digital in February 2025, fueled by AI data center demand for its NAND flash memory and solid-state drives. The stock now trades with a forward price-to-earnings ratio above 33, while the analyst consensus price target of $1,863 implies shares have moved slightly ahead of Wall Street's valuation.

Despite the sharp run, 86% of analysts maintain buy ratings on the name. The Motley Fool recommends dollar-cost averaging into the position rather than entering at current levels in a single transaction.

The separation from Western Digital has allowed SNDK to capitalize on accelerating infrastructure buildouts for AI workloads, where high-performance storage solutions command premium pricing. The company's pure-play exposure to NAND and SSD technology positions it at the intersection of two growth vectors: enterprise AI adoption and the ongoing shift from hard disk drives to flash-based storage.
