China’s A-share Indexes Turn Positive; CPO Stocks Lead Gains

The rotation into CPO names suggests the market is treating optical communication components as the cleanest listed proxy for AI datacenter buildout demand, rather than a broad risk-on move — the breadth of over 3,000 advancers makes the index turn look more like a sentiment repair than a sector-specific story. The sympathy gains in Zhongji Innolight and Eoptolink matter because they show the bid is spreading across the supply chain rather than concentrating in one name. Whether that leadership holds once the broader index loses its early momentum is the open question.
