The Taiwan Stock Exchange and Taipei Exchange announced trading restrictions on Aug. 26 for I-Chiun (2486.TW), Ability Opto-Electronics (3362.TW) and Myson Century, formerly Century* (5314.TW), effective Aug. 27. All three shares moved from continuous trading to call matching every two minutes. Ability Opto-Electronics faces a seven-business-day restriction through Sept. 4, while I-Chiun and Myson Century face five-business-day restrictions through Sept. 2. On Aug. 28, Myson Century briefly reached its 11th consecutive limit-up at NT$41.8 before falling to the NT$34.2 limit-down, a 20% intraday swing, with about 20,000 lots traded and 2,098 sell orders queued at mid-session. The rally reflected the company’s pivot toward healthcare, wellness products and AI unmanned vehicle systems, as well as short-squeeze dynamics. As of Aug. 26, margin short positions stood at 4,806 lots and securities-lending sales at 12,855 lots; after stock-dividend obligations, estimated buyback pressure exceeded 55,000 lots and potential securities-lending short-seller impairment reached NT$1.29 billion. I-Chiun recorded a price-to-earnings ratio of 226.29x, a price-to-book ratio of 10.21x and a turnover rate of 7.29% after meeting the public-disclosure threshold for five consecutive business days. Ability Opto-Electronics had been restricted within the previous 30 business days and triggered heightened-alert criteria again over five business days; its price-to-book ratio was 7.6x, or 3.24 times its industry average, and its turnover rate was 21.24%. Yuanta Securities sold NT$1.67 billion, or about $52.5 million, of the stock, representing 25.89% of daily trading value. Myson Century had also faced a restriction within the previous 30 business days and met heightened-alert criteria for three consecutive business days; its closing price had gained 59.71% over six business days and 123.71% across the latest 30-business-day period, while E.Sun Securities’ buy orders accounted for 33.45% of daily trading volume. Skyworth (6225.TW) and Pell Bio-Med (6949.TW) entered the potential-restriction watchlist after appearing as alert stocks on Aug. 25-26. The measures reflect trading-alert triggers and do not necessarily indicate fundamental problems, but restrictions can reduce execution flexibility, compress liquidity and heighten risks if selling pressure increases.
