Taiwanese chipmaker Vanguard International Semiconductor rose against a falling market, good news for its shareholders on an otherwise ugly day for Taiwan stocks.

• Vanguard's shares opened lower but turned sharply higher, at one point jumping close to 5%.
• August sales came in strong, up 8% from July and about 40% from a year earlier.
• Demand for AI servers and power management chips is driving the gain, though limited factory capacity caps how much the company can ship.
• Foreign investors bought heavily the day before, adding to the push.
• The wider Taiwan market fell hard the same morning, dropping more than 600 points.

Outlook: Vanguard expects both shipments and chip prices to edge higher this quarter, so the sales momentum should hold as long as AI demand stays firm.
