Sandisk Stock Is Surging Wednesday: What's Going On?

Sandisk Corp. (NASDAQ:SNDK) is gaining traction from rising AI-driven storage demand, tighter NAND supply expectations and longer-term customer commitments as investors look toward the company’s next earnings report. The stock rose more than 4% Wednesday, outperforming a volatile technology sector. The move follows growing investor focus on the company’s exposure to AI data center spending and improving expectations for NAND pricing. BMO Sees NAND Supply Tightness BMO analyst Harsh Kumar recently said he expects the broader memory industry to remain undersupplied through 2027 and potentially into 2028 as AI demand increases across DRAM, HBM and NAND. Kumar expects NAND to become the next major supply bottleneck and potentially experience the strongest price increases next year. He also noted that adding new fabrication capacity takes time, with plants typically requiring two to three years to build and costing about $8 billion to $10 billion. Cantor Pushes Back On Capacity Concerns Sandisk shares recently came under pressure after reports that Toshiba plans to expand hard-drive capacity. However, Cantor Fitzgerald analysts C.J. Muse, Matthew Prisco, Jamison Phillips-Crone and Galahad Caer argued that the sell-off was excessive, calling it a case "where the headline is worse than reality." They said demand continues to exceed supply and maintained their long-term bullish industry thesis. Institutional researcher Nicholas Mugalli also characterized the pullback as a potential buying opportunity.
