On 4 August 2026 the Taiwan Weighted Index stayed just above the 43,000‑point level, slipping marginally to 43,360.66. Institutional investors added roughly NT$25 billion, buoying memory‑chip and co‑packaged optics stocks, while major semiconductor leaders such as TSMC fell more than 2 %. The market focus was on mid‑cap rebound stocks and analysts urged a medium‑ to long‑term view ahead of U.S. economic data. Three days later, on 7 August 2026, the index surged 2.9 % to a new high of 44,611, breaking the 44,000‑point barrier. Both foreign and domestic funds poured in, concentrating on memory chips, copper‑clad laminates, ABF substrates and AI‑cooling companies. The rally was reinforced by gains in the Philadelphia Semiconductor Index and a modest rise in TSMC ADRs. After an initial opening gain, the market retreated below 44,217 as investors defended a seasonal trend line, and a newly announced 15 % U.S. tariff on polysilicon added pressure to silicon‑wafer makers. Trading volume remained robust, indicating sustained interest despite the short‑term pullback. Further data from the same day showed the index, after hitting the record, closed about 170 points lower. The week‑long rally added 1,106 points, pushing total market capitalization past NT$144 trillion. Foreign investors net bought about NT$20.2 billion, while domestic institutional investors added roughly NT$94.1 billion, focusing on memory chips, copper‑clad laminates, ABF substrates and AI‑cooling components. ETFs such as the 00685L “positive‑2” fund posted strong gains, and foreign and mainland Chinese investors trimmed holdings in panel and memory stocks, adding short‑term volatility.
