Zhongji Innolight A-share turnover tops 20 billion yuan, shares fall over 6%

The signal here is the pairing of a sharp decline with exceptionally heavy turnover, which points to a genuine repricing of positions rather than thin, headline-driven drift. Optical-module names sit close to the AI-infrastructure trade, so outsized activity in one of the mainland's busiest stocks can reflect sentiment shifts across that complex, not just company-specific news. Whether the elevated volume persists, and whether it stays concentrated in this name or spreads to peers, is the open question worth watching.
