SanDisk delivered the S&P 500’s top return last year, rallying more than 1,000% between February and December 2025. Since the spin-off from Western Digital, the company’s market capitalization has expanded to around $74 billion, propelled by an 11-month surge in demand for high-speed storage. Trading volumes have averaged roughly 13 million shares daily, underscoring heightened institutional interest in the stock.

The February 2025 separation from Western Digital allowed SanDisk to focus exclusively on its NAND flash and solid-state drive business. Data center revenue, now accounting for approximately 12% of total sales, is growing at a 42% year-over-year pace and is poised to become the primary growth driver. Hyperscale cloud providers have ramped purchases to accommodate AI training workloads, creating a widespread storage shortage that has enabled SanDisk to raise selling prices and surpass its cash generation target six months ahead of schedule.

Analysts project SanDisk will trade at roughly 31 times next-year’s earnings, a valuation premium above long-established tech leaders but below some AI hardware peers. Consensus estimates call for fiscal 2026 revenue of $10.45 billion and earnings per share of $13.46, reflecting strong operating leverage as fixed manufacturing costs are absorbed. Given this profile, many portfolio managers recommend dollar-cost averaging into the stock rather than deploying a lump-sum position, mitigating the risk of a near-term pullback following the stock’s rapid ascent.

Despite the current supply shortage, memory markets remain cyclical. J.P. Morgan analysts warn that once wafer capacity shifts back from high-bandwidth memory to standard NAND production, pricing pressure could intensify, leading to margin contraction. Their models indicate a potential downside of more than 50% from current levels if flash inventory builds exceed demand. Investors are thus advised to monitor fab utilization rates and customer inventory trends closely as early indicators of a market inflection.
