Shares of gallium arsenide foundry AWSC surged to the daily limit up and climbed back above their yearly moving average, good news for shareholders, though heavyweight and high-priced stocks across the Taiwan market were broadly weaker on the same day.

• AWSC's fourth-quarter capacity is already fully booked, with clear visibility on orders, breaking with the traditional off-season pattern.
• Its market share in China's handset market has expanded, with its PA products designed into Chinese-brand flagship phones, while order transfers from Korean customers have also beaten expectations.
• Non-handset applications are gaining traction at the same time, with drones, optical communications, low-earth-orbit satellites and solar materials progressively contributing to revenue.
• The company aims to cut the combined revenue share of handset and WiFi PAs to below 60% next year, diversifying away from reliance on a single market.
• High-priced stocks slumped the same day: Aspeed briefly hit limit down and lost the NT$16,000 level, while King Slide took two consecutive limit-down sessions after September revenue fell 30% month-on-month.

Outlook: With the gallium arsenide market recovering and its product lines diversifying, AWSC's near-term share performance looks positive, but the broader index remains volatile ahead of the 50,000-point threshold, with foreign investors net sellers for several sessions running.
