Why Sandisk Stock Finally Popped Today

SNDK shares jumped 21.5% today, recovering a portion of the 37% decline suffered over the prior four trading sessions. The sharp reversal follows investor reassessment of two headwinds that had hammered the stock: Chinese competition in memory chips and uncertainty around AI hyperscaler capital expenditure.

The rebound centers on renewed confidence in demand from hyperscalers including Google and OpenAI. Despite profitability questions facing those customers, their ongoing AI infrastructure buildouts require significant memory chip volumes—a core SanDisk product line. The rally suggests traders are betting that hyperscaler spending momentum will outweigh competitive and margin pressures in the near term.

The four-day selloff had pushed SNDK to oversold levels before today's pop. The stock remains well below its pre-selloff baseline, leaving a material gap that bulls will need sustained hyperscaler order flow to close.
