Taiwan's stock market fell Monday as investors cashed in gains after a big summer run — a mild negative for buyers, but a normal pause rather than a breakdown.

• The Taiex slipped about 1% after climbing more than 13% since late July.
• Traders took profits once the index neared a tough resistance zone, and trading volume dried up.
• Big tech led the drop — TSMC fell, along with Nanya Technology, MediaTek and Hon Hai.
• Nan Ya Plastics and Formosa Plastics sank hard, dragged down by Nanya's slide; banks and insurers also fell.
• Foreign investors were net sellers on the main board.

Outlook: Attention turns to Nvidia's earnings this week, which will set the tone for AI-linked chip stocks in Taipei.
