China A-Share Grid Equipment Sector Rises; Zhiguang Electric Hits Limit Up

A broad grid-equipment rally without a named catalyst is the notable part: the move is sector-wide rather than a single-name story, which suggests positioning or sentiment rather than company-specific news. The limit-up in Zhiguang Electric and the near-limit move in Huatong Cable matter mainly as signals of how concentrated demand for the theme has become. Whether the sector can hold gains once the volatile session passes is the open question, since nothing in the disclosed material explains the buying.
