TAIPEI (Taiwan News) — Taiwan's stock market reached new highs Tuesday, led by TSMC and Delta Electronics.
The Taiwan Capitalization Weighted Stock Index (TAIEX) rose as much as 1,013.16 points during trading, marking the second-largest intraday gain on record. It finished up 927.56 points at 34,700.82, the second-largest single-day point increase, according to CNA.
Turnover totaled NT$837.07 billion (US$26.7 billion). The combined market capitalization of listed companies reached NT$113.99 trillion, exceeding the previous record of NT$110.08 trillion set Monday.
TSMC rose 3.42% to close at a record NT$1,965, contributing about 540 points to the TAIEX. Delta Electronics gained 6.13% to NT$1,385, contributing roughly 68 points.
Foxconn gained 1.53% to NT$232. MediaTek added 1.67% to close at NT$1,825.
Printed circuit board makers rose after Morgan Stanley said demand for Ajinomoto Build-up Film substrates could enter another upcycle. Nan Ya PCB exceeded NT$500 for the first time in nearly four years, while Unimicron Technology and Kinsus Interconnect Technology also reached limit-ups, according to CTEE.
ABF is an insulating material used in advanced semiconductor packaging, and demand is rising with artificial intelligence, high-performance computing, and 5G applications, according to Pocket Securities. Upstream materials suppliers, including Glotech Industrial, Taiwan Glass, Nan Ya Plastics, and Fulltech Fiber Glass, also posted gains.
The memory sector saw active trading as shortages of some chips led to continued price increases. Macronix International hit its daily limit at NT$113.5, a new high.
PSMC also hit limit-up. Winbond Electronics and Phison Electronics posted notable gains.
Companies in low-Earth-orbit satellite supply chains moved higher, including Unitech PCB and Win Semiconductors, both of which reached limit-ups. Silicon photonics-related firms Fiber Optic Communications, Pcl Technologies, LuxNet, and FitTech also hit their daily limits.
Passive component makers rose, led by Yageo. The company moved above NT$300, gaining 6.93% to NT$301.
Walsin Technology reached limit-up for a second consecutive session at NT$149. Leatec Fine Ceramics also hit its second straight daily limit.
The gains followed signals of price increases for multilayer ceramic capacitors (MLCCs), the most widely used passive components across electronic devices. Global MLCC leader Murata hinted at a potential price adjustment, while Samsung Electro-Mechanics is reportedly planning a price hike starting in April, according to CTEE.
Liu Cheng-yu (留政鈺), senior vice president of research at First Capital Management, said recent declines in US equities were partly linked to concerns that AI could disrupt traditional software companies. Taiwan’s technology sector, however, is largely focused on hardware.
Liu noted that semiconductor shares have continued to advance this year. From the start of 2026 through Monday, the PHLX Semiconductor Index rose 15.9%, while the S&P 500 fell about 0.1% and the Nasdaq Composite declined 2.6%.
Senior analyst Chien Po-yi (簡伯儀) said the TAIEX has closed higher for six consecutive sessions and remains above key moving averages. With sector rotation continuing, buying interest in stronger stocks could continue.
