China A-share PCB Stocks Rebound; Yidun Electronics Hits Limit Up

The rebound looks technical rather than fundamental: a broad, single-session recovery across PCB names after recent swings, with no fresh catalyst in the item. The dispersion matters — one limit-up and a handful of mid-single-digit gainers suggest selective positioning, not a sector-wide re-rating. For RWA and tokenization watchers, A-share PCB sentiment is a read-through on China's hardware supply chain, not on crypto rails. Whether the bounce holds beyond the session, or fades like the prior swings, is the open question.
