Sandisk shares surged 143% in January and have rallied more than 1,700% over the past year, driven by a severe memory chip shortage and booming AI demand for data-center capacity. On a single trading day last week, the stock jumped 15%, pushing its price level to a record high that sits roughly 380% above its 200-day moving average—an 8-sigma statistical anomaly given the historical standard deviation of ±45.40%. Such an extreme deviation underscores both the ferocious momentum behind the rally and the nonlinear risk that could emerge if supply-demand dynamics shift or broader market sentiment turns.

In the second quarter, Sandisk reported revenue of $3.03 billion, up 61% year-over-year, and adjusted earnings per share of $6.20, more than doubling consensus expectations. Net income climbed by over 670% compared with the prior year, while gross margins expanded to an all-time high above 50%. Management cited robust enterprise and hyperscale customer orders, particularly for its high-performance NAND flash modules and solid-state drives designed for AI inference workloads.

Looking ahead, the company forecast third-quarter adjusted EPS between $12.00 and $14.00, implying a further doubling of profitability on sustained pricing power. NAND flash contract prices have risen sharply over the past six months, reflecting tight industry supply and strong backlog commitments from cloud service providers. Wall Street analysts have responded by raising target prices across the board—benchmark firms have lifted their estimates by as much as 60% in recent weeks—while maintaining unanimous buy ratings based on the expectation of continued margin expansion and cash flow generation.
