Why Is Sandisk (SNDK) Stock Price Up 11.90% Today, Sep 4? AI Storage Demand Drives Massive Double-Digit Rally

Sandisk (SNDK) rallied 11.9% as investors repriced the memory sector on expectations of AI-driven NAND demand and tight supply, reinforced by peer strength and Nvidia's Hugging Face acquisition as an AI capex read-through. The move appears headline- and sector-led rather than driven by new Sandisk guidance, leaving near-term follow-through dependent on NAND pricing data, enterprise SSD demand, and any company-specific order or outlook commentary.
