Hong Kong optical comm stocks slide; Xizhi Tech down 8%

The broad, synchronized slide across Hong Kong-listed optical communication names suggests a sector-wide repricing rather than company-specific shocks. The magnitude of the declines, with leaders like Xizhi Tech down 8%, points to possible sentiment shifts around demand outlooks or valuation recalibration after prior gains. The fact that component makers and assemblers are all affected indicates the move is likely tied to supply-chain or end-market concerns. What warrants watching is whether this is a one-day correction or the start of a sustained de-rating, and whether mainland A-share optical peers follow suit.
