SanDisk Shares Are Already Up 105% in 2026. How Much Higher Can SNDK Stock Go This Year?

With AI-backed demand, memory maker stocks are in overdrive. SanDisk (SNDK), after a strong 2025, has gone ballistic in the first few weeks of 2026. For year-to-date (YTD), the stock has returned 105%, and there appears to be no fatigue in the rally. 

Of course, there are strong fundamental factors that back the rally. Reports indicate that SanDisk is likely to double the price of its high-capacity 3D NAND memory devices. Further, the surge in demand is not temporary, and Nomura Securities expects short-term shortages coupled with mid-term growth of demand to be driven by AI.
