SanDisk shares delivered a remarkable 500% gain over the course of 2025, outpacing nearly every other component of the S&P 500. That momentum carried into 2026, with the stock surging an additional 43% in just the first three trading sessions of the year. In early January, SanDisk climbed 28% in a single session, marking one of its best trading days ever and underscoring the strong investor appetite for memory and storage names.

On January 6, comments by Nvidia CEO Jensen Huang at CES in Las Vegas highlighted an “unserved market” for AI-specific storage and memory. Investors responded immediately, sending SanDisk shares up 27% the following day. Huang’s assertion that AI workloads will likely create the largest storage market in history provided a clear catalyst, driving a surge in demand forecasts and reinforcing SanDisk’s positioning as a key beneficiary of the AI data center buildout.

At 10:13 AM EST on January 7, SanDisk triggered a Power Inflow alert at a price of 336.55, signaling heavy institutional buying pressure. This bullish order-flow indicator appeared after the stock had dipped roughly 4% in the hour preceding the alert, suggesting smart-money accumulation. Traders who track these signals view it as confirmation that large funds are positioning for further upside in SNDK shares.
