On April 13, 2026, the Taiwan stock market (Taiex) closed at 35457.29 points, an increase of 39.46 points. The total transaction value was NT$778.766 billion. The three major institutional investors collectively net sold NT$5.005 billion. Dealers (proprietary traders) net bought NT$3.988 billion, investment trusts net bought NT$7.137 billion, and foreign and Mainland Chinese investors net sold NT$16.13 billion after four consecutive days of net buying. Foreign investors' top 5 net sell stocks/ETFs were UMC (聯電) with 50,562 shares, Unimicron (欣興) with 30,543 shares, Fubon Taiwan High Dividend ETF (00919), Fubon Global Innovation Active ETF (00988A), and Fubon Taiwan Growth Active ETF (00981A). Foreign investors' top 5 net buy stocks/ETFs were Formosa Plastics (台塑) with 57,997 shares, Formosa Chemicals & Fibre (台化) with 52,424 shares, Yuanta Taiwan 50 ETF (0050), Nan Ya Plastics (南亞), and Yageo (國巨). Huang Wen-ching, Vice President of Taishin Securities Investment Advisory, stated that since the start of US-Iran negotiations, the Taiex index reached a new high on April 10 and again on April 13, indicating strong investment sentiment. However, significant disagreements in the US-Iran negotiations make a short-term agreement unlikely, leading to a wait-and-see approach in the market, though it does not affect the bullish sentiment. Several sectors performed strongly, and the market is observing international developments. Strong industry sectors with good fundamentals, such as passive components, packaging and testing, some optical communication, and silicon photonics, showed stable performance. Tourism and leisure stocks also strengthened, with no signs of weakening. Looking ahead, the market will focus on TSMC's investor conference on April 16. If US-Iran negotiations do not completely break down, the stock market atmosphere is cautiously optimistic, and the Taiex index is expected to reach new highs.
