標普將梅賽德斯-奔馳評級下調至“A-”；展望穩定。

After a sharp early drop, China’s three major A-share indices staged a brief rebound—STAR 50 briefly turned positive—but weakness returned in the afternoon and volume contracted. At the close, Shanghai Composite -1.10%, Shenzhen Composite Index -2.57%, ChiNext Index -3.99%, STAR 50 -2.6%; turnover CNY1.6trn; more than 4,700 stocks fell. Most sectors were down; compute‑power infrastructure-related names led losses, with PCB, CPO and component stocks among the biggest decliners. Seed, grain and power sectors outperformed, and banks showed afternoon buying interest.

Semiconductor equipment ETFs from GF, Guotai and E Fund, among others, turned positive after an early-session decline of more than 6%.
