December 18, 2025 — Sandisk Corporation stock rallied sharply on Thursday, extending a powerful 2025 run as investors piled back into memory and storage names. The move came amid a one-two catalyst: Micron’s standout outlook for AI-driven memory demand and a fresh wave of bullish analyst commentary on Sandisk’s positioning as a “pure-play” NAND flash beneficiary of the current pricing cycle.

Sandisk Corporation is back in the spotlight on Tuesday, December 16, 2025, as investors weigh a sharp rebound in the shares against a market narrative that’s increasingly dominated by AI-driven data center buildouts, memory pricing, and the question of whether the storage rally is cyclical—or structural.

Sandisk Corporation ended Monday, December 15, 2025, on another volatile note as investors continued to reassess the fast-moving “AI storage” trade and position ahead of a data-heavy Tuesday. The stock finished regular trading lower, then stayed relatively calm in early after-hours trading—an important detail given how sharply the shares have been swinging in recent sessions.
