TAIPEI (Taiwan News) — Taiwan’s stock market briefly climbed above the 44,000-point level on Tuesday to set a new intraday record before giving up gains as investors locked in profits following a strong recent rally.
The Taiwan Capitalization Weighted Stock Index (TAIEX) reached an intraday high of 44,097.63 points. It closed down 119.03 points at 43,525.37 points, according to CNA and CTEE.
Turnover totaled NT$1.47 trillion (US$46.8 billion). Market capitalization of listed companies stood at NT$141.97 trillion, according to the Taiwan Stock Exchange.
TSMC fell 1.73% to NT$2,270. Foxconn declined 0.77% to NT$259.
Delta Electronics rose 2.62% to NT$2,350, and MediaTek gained 0.47% to NT$4,265. Both recorded historical intraday and closing highs.
Trading activity also showed signs of broadening participation in higher-priced stocks. The number of listed shares trading above NT$1,000 rose to 52 at the close, with new additions including printed circuit board maker Unimicron Technology and construction and engineering services firm Acter.
Capital rotated into silicon photonics and co-packaged optics. Ezconn hit its daily limit-up at NT$2,265, LandMark Optoelectronics advanced 8.03% to NT$3,160, and Fiber Optic Communications rose 4.61% to NT$885.
CPO is a silicon photonics application that integrates electronic and optical components into the same package. By placing optical engines closer to CPUs and GPUs, it shortens signal transmission distances, reducing latency and power consumption, according to Sinotrade.
The memory sector also attracted strong buying interest. Winbond Electronics hit its daily limit-up, Nanya Technology rose 2.53%, PSMC gained 4.73%, and Macronix International advanced 5.25%.
Analyst Hsieh Chen-yen (謝晨彥) said Taiwan’s equity market is likely to remain volatile in the short term following the recent rally, with profit-taking pressure emerging at higher levels. He added that artificial intelligence has shifted from a short-term investment theme to a broader phase of strategic competition.
He noted that AI-related investment is expanding beyond chips into wider data center infrastructure. This includes high-bandwidth memory, liquid cooling systems, high-power power supply equipment, server rack integration, and high-speed connectivity components.
Hsieh said Taiwan’s semiconductor and electronics ecosystem is well-positioned to benefit, given its integrated manufacturing base across these segments. He described the current trend as a potential broadening of the AI growth cycle, with multiple parts of the supply chain likely to see stronger demand rather than growth being concentrated in a few core chipmakers.
However, he cautioned that the index remains at elevated levels after a rapid advance, making short-term fluctuations likely. He advised investors to avoid chasing gains and instead focus on companies with stronger fundamentals and clearer visibility in AI infrastructure demand.
