China A-share battery supply chain stocks slump; Shidai Wanheng hits limit-down

The move is notable less for any single name than for its breadth: the selling ran through components and equipment alike, suggesting a sector-wide repricing rather than an issue-specific reaction. That pattern points to sentiment on the battery supply chain as a whole, where positioning and demand expectations tend to move together. Shidai Wanheng's limit-down is the clearest signal of how forcefully the pressure hit. Whether the weakness stays concentrated in the smaller component and equipment names or spreads to the larger chain is the open question worth watching.
