TAIPEI (Taiwan News) — Taiwan’s benchmark stock index traded around the 47,000-point level throughout Wednesday.
The Taiwan Capitalization Weighted Stock Index, or TAIEX, closed up 893.08 points at 47,018.99. Turnover totaled NT$1.32 trillion (US$41.4 billion), according to Taiwan Index Plus.
Large index-weighted stocks, which have the greatest influence on TAIEX movements, showed mixed performance. TSMC rose 3.94% to NT$2,505, providing main support for the index, according to Anue.
MediaTek gained 2.12% to NT$4,335, Delta Electronics added 2.05% to NT$1,990, and ASE rose 3.38% to NT$703. Foxconn fell 1.2% to NT$248.
The silicon wafer sector continued its gains. Sino-American Silicon Products, GlobalWafers, Formosa Sumco Technology, and Wafer Works all hit their daily limit-ups, according to CTEE.
Silicon wafers, a foundational material for semiconductor production, reflect broader demand trends across both mature and advanced process nodes. As market conditions tighten, major Taiwanese producers have indicated continued price increases.
Semiconductor equipment stocks also attracted buying interest. Mirle Automation, Gudeng Precision Industrial, and Gallant Micro Machining all reached limit-ups, reflecting expectations of sustained demand driven by AI-related advanced manufacturing and advanced packaging expansion.
The passive component sector also rose on reports of a new round of price increases. Leader Yageo has reportedly informed clients that it will raise quotations across multiple capacitor products from Wednesday, according to EBC.
The company reached a post-split record high of NT$1,220 during the session before easing to close flat at NT$1,140. Kaimei Electronics, Polytronics Technology, Hua Jung Components, and Prosperity Dielectrics all closed at limit-ups.
Power semiconductor stocks, which had recently attracted investor interest, showed mixed performance. Upi Semiconductor and Advanced Power Electronics reached daily limits.
Panjit International and Eris Technology rose more than 3%. In contrast, Mosel Vitelic, Sdi, Episil-Precision, Episil Technologies, and Vanguard International Semiconductor fell more than 3%.
Memory-related stocks weakened after China’s NOR flash market leader GigaDevice signaled potential price declines, while South Korean memory stocks also eased. Winbond Electronics, Nanya Technology, Macronix International, and PSMC all fell more than 6%.
Senior analyst Lee Yung-nien (李永年) said the memory sector’s performance reflects a faster rotation among individual stocks and sectors within the TAIEX.
Panel makers were among the most actively traded stocks, but performance was weaker. AUO and HannStar Display both fell more than 6%, while Innolux also edged lower, indicating a divergence between trading volume and price performance.
Market analyst Tsai Ming-han (蔡明翰) said recent gains in equities have been driven less by short-term catalysts and more by expectations of long-term AI demand growth. He added that TSMC’s US-listed shares recently reached a record high, helping attract global capital back into semiconductor supply chains.
Concord Securities Chief Investment Officer Liao Chi-hung (廖繼弘) noted that earlier overheated conditions have eased, while domestic investors helped stabilize the market. He added that Taiwan equities remain in an upward trend supported by fundamentals and upcoming second-quarter earnings, with the index expected to continue fluctuating while testing higher levels.
Fubon Research Chair Chen Yi-kuang (陳奕光) said that as the second half of the year begins, investors will start assessing whether the large-scale AI investments made by major cloud companies can be effectively turned into profits. He said the market is not bearish on AI, but has become more cautious about overly optimistic expectations, and suggested investors remain alert to potential risks.
