Taiwan chip packaging firm Chipbond is rallying hard as its move into optical communications pays off, good news for holders and for the broader optical chip trade.

• Chipbond stock jumped more than 9% at one point, crossing above NT$206.
• Foreign investors, local funds, and dealers all turned buyers at once, snapping up over 9,000 lots in a single day.
• Profit margins improved sharply last quarter, helped by price increases and new silicon photonics work.
• The company is sitting on more than 30 optical communications projects and pushing into LPO, a cheaper way to move data inside AI data centers.

Outlook: Analysts expect Chipbond's optical business to grow another 30% this quarter, which should keep lifting profits.
