Why Sandisk Stock Rocked the Market Last Month

SNDK jumped more than 11% in September 2026 as traders priced in a longer-than-expected memory shortage tied to AI demand.

Two forecasts drove the move. INTC's CEO warned that memory scarcity could extend to 2028. C went further, predicting shortages lasting until 2031. The three-year gap between those timelines matters: the longer the supply squeeze, the longer flash memory makers like SNDK can command pricing power. That is interpretation, not reported fact.

Analyst support added fuel. Rosenblatt rates SNDK a buy with a $2,400 price target. Mizuho also upgraded the stock. The upgrades arrived alongside SNDK's addition to the S&P 100, which broadens its institutional ownership base and puts the name in front of index-driven buyers.

The bull case rests on SNDK's position as a trusted flash memory manufacturer positioned to benefit from AI infrastructure build-out. Note that the rally leaned heavily on forward-looking shortage forecasts rather than reported results, so the stock now carries expectations that supply tightness persists for years.
