The TAIEX, Taiwan’s benchmark stock index, rose 191 points, or 0.5%, to 39,807 in Tuesday morning trading, tracking gains in US stock futures ahead of a wave of earnings reports from major technology companies. The index set a record high for the third consecutive session, having briefly crossed the 40,000 mark for the first time just minutes after the market opened on Monday. Sentiment remained buoyant on optimism over AI infrastructure development and regulators’ plans to relax a long-standing rule that capped fund managers’ exposure to any single stock at 10% of assets. Gains were led primarily by the energy minerals, health technology, and commercial services sectors. Among the standout performers, Macronix International, Kaimei Electronic, and Chieftek Precision each jumped around 10%. In contrast, contract chipmaker TSMC, which represents more than 40% of the market’s total capitalization, slipped 1.1% as traders took profits following Monday’s advance.
