China A-share CPO and Optical Communication Stocks Fall in Afternoon Session

The selloff is concentrated in the CPO and optical communication names that have been the most crowded AI-infrastructure trades in China's A-share market, so the sharp moves in Star-Net Ruijie and Xunjiexing say more about positioning than about any company-specific development. The read-through is that domestic AI hardware sentiment can decouple from global demand narratives when local flows turn. Whether the weakness broadens into other AI supply-chain segments, or stays contained to the highest-beta optical names, is the open question worth tracking.
