Why Is SK hynix (SKHY) Stock Up 7.05% Today, Sep 9? Memory Recovery Hopes and Strong HBM Demand Lift Shares

SK hynix shares jumped 7.05% as investors rotated into memory names on improving expectations for the DRAM/NAND cycle and strong AI-driven HBM demand. A more constructive sell-side view and light positioning likely amplified the move, with no company-specific catalyst cited. Short term, sentiment may support further relative strength in AI memory exposures, but follow-through will hinge on HBM shipment trends, pricing data, and hyperscaler order signals.
