AI Caution Rocks Taiwan Stocks, TAIEX Dips
17 Sep
Summary
- Taiwan's stock index fell due to investor caution over AI development.
- TSMC shares saw a slight increase, while MediaTek and Foxconn declined.
- Cybersecurity and quartz component stocks gained amid AI focus.

Taiwan's benchmark stock index, the TAIEX, extended its losses on Tuesday, closing down 351.03 points, or 0.77%, at 45,511.49. Investor sentiment remained cautious following signals from major US tech firms suggesting a slower pace for AI model development.
Leading stocks showed mixed performance. Taiwan Semiconductor Manufacturing Company (TSMC) added 0.21%, while MediaTek and Foxconn experienced declines. However, Delta Electronics and ASE saw gains, reflecting sector-specific movements within the broader market.
Cybersecurity stocks garnered significant interest, with several hitting their daily limits. This surge followed Nvidia CEO Jensen Huang's identification of the sector as crucial for AI advancements. Quartz component manufacturers also advanced due to the increasing demand from AI servers and high-speed communications.
Conversely, the memory sector faced pressure due to high inventory levels reported by Kioxia, potentially leading to oversupply. Cooling module stocks also saw profit-taking after previous gains based on AI server upgrade expectations.
Analysts anticipate the market will remain range-bound through the fourth quarter, with AI-related sectors continuing to be a core investment focus. Key areas include AI infrastructure, semiconductor construction, advanced packaging, and optical communications.
