The TAIEX, Taiwan’s benchmark stock index, climbed 902 points, or 2.0%, on Wednesday to close at 46,459, extending its winning streak to a fourth consecutive session. The index set a new record high and finished above the 46,000 mark for the first time, with nearly all sectors advancing, including electronic technology, financials, and commercial services.
Sentiment was buoyed by gains on Wall Street and sustained optimism over AI-related investment. Confidence was further supported by positive data from China, where business activity in the mainland’s private sector expanded in May at its fastest pace in three months.
Electronic technology stocks gained 1.8%, as persistent enthusiasm over AI demand continued to underpin the sector. TSMC, the world’s largest contract chipmaker and a heavyweight accounting for more than 40% of the market’s total value, rose 1.7%, adding to a 1.1% increase in the previous session. Among other major names, Delta Electronics advanced 3.2%, Hon Hai Precision added 2.8%, and ASE Technology jumped 4.9%.
