Why Sandisk Stock Rocked the Market Last Month

Sandisk stock surged over 11% in September 2026 due to optimistic forecasts about persistent memory shortages driven by AI demand. Intel's CEO warned of memory scarcity extending to 2028, while Citigroup predicted shortages lasting until 2031. Analyst upgrades from Rosenblatt (buy rating, $2,400 target) and Mizuho, plus Sandisk's addition to the S&P 100 index, further boosted the stock. The company is well-positioned as a trusted flash memory manufacturer to benefit from the AI infrastructure build-out.
