China Stocks Mixed at Midday as Solar Surges, ChiNext Gains 1.24%

The divergence between the broad Shanghai Composite and the growth-heavy ChiNext and STAR 50 points to a market rotating toward policy-sensitive, high-beta sectors rather than a uniform risk-on move. Solar's cluster of limit-up names, including Maxwell and Jinko, is the clearest signal of concentrated conviction in one theme, while the breadth — 4,457 advancers against 660 decliners — suggests the rally is wider than the headline indices imply. Whether solar leadership holds through the full session, or the STAR 50's sharp intraday pullback foreshadows fading momentum, is the open question worth watching.
