Shennan Circuits hits daily limit-up with turnover of 3.038 billion yuan

A limit-up lock on roughly $420 million of turnover signals conviction rather than a thin squeeze, which matters for a circuit-board supplier whose demand story is tied to AI and high-end electronics buildout. The move is a read on how aggressively domestic capital is repricing hardware supply-chain names, not a company-specific disclosure — the item carries no catalyst. Worth watching is whether the locked bid holds into the next session and whether turnover stays this heavy, since a limit-up on volume that large can mark either accumulation or distribution.
