Taiwan chipmaker Win Semiconductors opened sharply higher, good news for holders betting on the AI and optical networking buildout.

• A European brokerage repeated its positive call, saying the optical side should get stronger month by month and ramp up next year.
• The stock climbed about 6% early, with heavy trading volume.
• Third-quarter sales are expected to grow at a low double-digit pace from the prior quarter, led by optical and infrastructure work.
• Foreign investors were big buyers the day before, with Goldman Sachs, Merrill Lynch and UBS Singapore among the main buying desks.
• The company sees demand from 800G and 1.6T optical links, satellites and AI data centers pushing profit to a six-year high next year.

Outlook: The product mix keeps shifting away from phones toward AI and optical gear, which should support earnings into next year if that demand holds.
