China A-share semiconductor sector weakens; Rockchip hits limit-down

A broad, news-free selloff in A-share semis often reflects positioning and liquidity rather than fundamentals, and Rockchip's limit-down is the clearest signal of that. The absence of company-specific catalysts makes it hard to attribute the weakness to any single earnings or policy trigger. What matters next is whether the declines stay concentrated in individual names or spread across the wider domestic chip supply chain, and whether any official disclosure later explains the move.
