Taiwan stocks jumped to a fresh high as foreign investors kept buying, led by a record-setting MediaTek and a big rush into the two panel makers, AU Optronics and Innolux — good news for Taiwanese shareholders and the index's push toward 50,000.

• MediaTek hit a new all-time high and was the most heavily traded stock, pulling the whole market up more than 500 points.
• Foreign investors bought heavily for a third straight day, targeting panel makers AU Optronics and Innolux plus actively managed Taiwan ETFs.
• The three big institutional groups (foreign, dealers, local funds) all bought together, and foreign investors also cut their short bets on index futures.
• The Fed raised rates last week but the dollar weakened anyway, making it more attractive for foreign money to flow back into Taiwan.
• TSMC's chairman joked he hopes his stock catches up to MediaTek's share price, feeding investor chatter about where the chip stocks go next.

Outlook: Trading volume may thin out over three shortened holiday weeks, but the year-end shopping season and window-dressing should keep the index supported near 45,000 with a shot at 50,000.
