Sandisk Takes the Lead: AI Storage Sparks 2026’s Top Market Run
SanDisk has surged as 2026’s top S&P 500 performer, rising about 780% year‑to‑date and more than 3,900% since its 2025 spin‑off from Western Digital. The rally is driven by an AI storage boom that boosts NAND flash demand across data centers and devices, aided by disciplined memory supply and rising NAND prices. While Micron trails, the memory cycle remains highly cyclical, so investors should expect greater volatility in the second half of 2026 even if profits stay solid and AI infrastructure spending remains robust.
