China A-share computing power leasing stocks jump; Runjian shares hit limit up

The move looks thematic rather than company-specific: a single name hitting its daily limit pulled a cluster of computing power leasing peers higher, which suggests the concept label is doing more work than individual fundamentals. That matters for traders tracking how loosely defined AI-infrastructure baskets in the A-share market can move on sentiment. Whether the rally broadens beyond these localized gains, or fades once the limit-up name cools, is the open question worth watching.
