TAIPEI (Taiwan News) — Taiwan’s stock market opened higher on Wednesday but retreated as selling pressure emerged, with the Taiwan Capitalization Weighted Stock Index, or TAIEX, falling after a mid-session gain of more than 450 points.
It closed down 101.49 points at 33,337.62. Turnover totaled NT$736.4 billion (US$23.1 billion), according to CNA and CTEE.
TSMC declined 0.27% to NT$1,840. MediaTek fell 1.85% to NT$1,590, Delta Electronics dropped 2.26% to NT$1,515, while Foxconn rose 0.25% to NT$200.5.
Memory stocks came under pressure despite Nanya Technology’s private placement attracting major international investors, including Sandisk, Kioxia, SK Hynix’s Solidigm, and Cisco. Nanya opened at its daily limit-up but ended the session down 0.44%, as weakness in the broader memory sector dominated.
Other memory-related companies, including Macronix International, Team Group, and Goldkey Technology hit limit-downs. Innodisk, Adata, Winbond, PSMC, Transcend, Elite Semiconductor, Apacer, Silicon Power, and Phison Electronics also posted declines.
In contrast, firms linked to low-Earth orbit (LEO) satellites continued to show gains. Universal Microwave Technology, Gemtek Technology, Chin-Poon Industrial, Hitron Technologies, Lightel, and Co-Tech Development reached daily limits.
Optical communication companies supporting satellite systems, such as LandMark Optoelectronics and Intelliepi, also recorded intraday limit-ups. The performance follows the recent Satellite 2026 exhibition, where 21 Taiwanese companies showcased their technologies, highlighting the increasing role of LEO satellites as critical infrastructure rather than supplementary networks.
Concerns over potential raw material shortages affecting plastics and sanitary products supported gains in the petrochemical and plastics sector. Usi, Asia Polymer, and Taita Chemical reached limit-ups.
Marbo Investment CEO Wang Jung-hsu (王榮旭) noted that Taiwan's stock market remains sensitive to news. Investors are reducing holdings ahead of the weekend due to ongoing Middle East geopolitical uncertainties.
Wang added that while foreign investor sentiment has slightly improved, overall market caution remains. Monitoring oil prices, inflation, and US Treasury yields will be important, as rising costs and inflation concerns could continue to affect equities.
