Taiwanese chipmaking parts maker Gudeng jumped to its daily price limit, good news for shareholders riding the advanced-chip boom.

• Gudeng makes the sealed carriers that protect EUV photomasks, a key part for the most advanced chipmaking.
• The stock gapped up at the open and locked at its limit, with far more buy orders queued than shares traded.
• Foreign investors have been net buyers for six straight sessions, and local dealers joined in too.
• Chairman Chiu Ming-chien expects advanced packaging to take a bigger share of sales from 2026 through 2028, with double-digit growth in that business.

Outlook: As TSMC keeps pushing advanced processes and packaging, demand for these consumable carriers should keep rising into next year.
