China A-share robot stocks extend rally; Jingcheng shares up 3rd limit day

The breadth of the move — multiple names up sharply alongside consecutive limit-ups in Jingcheng and Fulai — suggests this is a sector-wide rotation into robot-concept names rather than a single-stock story. Limit-up streaks in A-shares tend to reflect momentum and constrained supply more than fresh fundamentals, which makes the durability of the rally the key question. Whether the buying broadens beyond the current cluster or narrows back to the leaders is worth watching, since a widening list of gainers would signal more conviction than a top-heavy tape.
