SanDisk Shares Climb 600% YTD as Short Interest Hits Record High
SNDK•SanDisk's shares have surged 600% year-to-date and over 50% in the past month, coinciding with record-high short interest levels. This reflects AI-driven memory chip demand and tight supply enabling price hikes and fueling both bullish momentum and bearish skepticism.
1. Record-High Rally and Short Interest
SanDisk's shares have exploded higher in 2026, rising roughly 600% year-to-date and over 50% in the past month. At the same time, short interest has climbed to its highest level ever, suggesting that bearish investors are betting on a potential setback after this unprecedented rally.
2. AI-Driven Demand and Supply Tightness
The surge is being driven by robust AI capital expenditures, with hyperscalers building data centers that require vast amounts of memory. Persistent supply tightness in the memory chip market has allowed manufacturers to hike prices, boosting revenues but also raising concerns about sustainability of current valuations.
