ChiNext Index Rebounds 4.16% as Robot Concept Stocks Surge

The scale of the intraday reversal, from a 3% morning drop to a 4.16% close, points to dip-buying conviction rather than a single catalyst, and the concentration in robot-concept names like Unitree suggests thematic momentum is doing much of the work. The breadth, with more than 4,500 stocks higher and turnover near 1.97 trillion yuan, matters more than the index print because it signals participation beyond one crowded trade. Whether robot names can hold their gains once limit-up flows fade, and whether turnover sustains at this level, is the open question for mainland risk appetite.
