Taiwan Stocks Surge 85% on AI Chip Boom
Taiwan’s main stock market index has risen sharply because investors are buying technology and chip companies.
These companies are benefiting from huge spending on artificial intelligence equipment.
Taiwan Semiconductor Manufacturing Company is especially important because it makes up more than 40% of the index.
Some other companies, such as King Slide Works and MediaTek, also gained a lot.
Traditional businesses like plastics and textiles did not rise as much.
The index has gained about 85% since August 2025, according to one analyst.
However, investors are now worried that AI companies may be too expensive.
These concerns have caused the market to fall from its June peak and become more volatile.
Taiwan’s TAIEX has risen roughly 85% from August 2025 to about 44,800.
The rally has been led by chip and AI-related companies, especially TSMC.
Taiwan Semiconductor Manufacturing Company accounts for more than 40% of the index’s market value.
