TAIPEI (Taiwan News) — Taiwan’s stock market fell on Friday, recording its largest single-day drop in over a month as electronics, traditional industries, and financial shares weakened.
The Taiwan Capitalization Weighted Stock Index, or TAIEX, fell 443.53 points to end at 25,580.32, with turnover reaching NT$480 billion (US$15.7 billion). Despite the decline, the index gained 1.95 points for the week, marking a five-week winning streak, according to CNA and CTEE.
TSMC fell 1.52% to NT$1,300, cutting its market value by NT$518.6 billion. Over three sessions, the stock dropped from NT$1,340, reducing TSMC’s market capitalization by more than NT$1 trillion to NT$33.71 trillion.
Foxconn slid 4.57% to NT$219.5. MediaTek lost 2.6% to NT$1,310, and Delta Electronics dropped 4.07% to NT$848.
In contrast, Techman Robot debuted with a rally, climbing 107% from NT$238 to NT$493, an increase of 107%. The rise generated gains of nearly NT$260,000 per lot, or 1,000 shares, for investors.
Lotus Pharmaceutical also performed strongly despite US plans to impose a 100% tariff on imported pharmaceuticals starting Oct. 1. The stock closed at the daily limit of NT$255 for a third consecutive session, rising 34% over five sessions following the announcement of a NT$20 billion acquisition that will position it among the world’s top 20 specialty drugmakers.
In traditional industries, plastics, machinery, cables, rubber, autos, and construction sub-indexes all fell more than 1%. Glass stocks led losses with a decline exceeding 7%.
Walsin Lihwa traded heavily as global copper prices weakened. The stock closed 4.39% lower at NT$25.05 with 244,000 lots, the second-highest market volume.
Shipping shares also retreated. Evergreen Marine remained optimistic, citing expected fourth-quarter demand, while Yang Ming Marine Transport took a more cautious stance.
Mega International Investment Services Vice President Huang Kuo-wei (黃國偉) noted the TAIEX has climbed over 9,000 points since its April low of 17,306.97, prompting some investors to take profits. PGIM High Growth Fund manager Liao Ping-kun (廖炳焜) said September saw multiple record highs and warned of potential short-term volatility with upcoming Mid-Autumn Festival and National Day holidays.
Liao added that Taiwan’s artificial intelligence-driven growth remains strong, supported by continued investment from global technology leaders and steady increases in Nvidia’s GB-series shipments. He highlighted long-term opportunities in AI-related suppliers, advanced chip manufacturing, chip design, edge computing, optical communications, memory, specialty chemicals, heavy electrical equipment, and biotechnology.
