Opened Lower and Lost the 45,000-Point Mark
Affected by across-the-board losses in the four major U.S. indices, with the Nasdaq and Philadelphia Semiconductor Index both falling over 1%, and a 643-point plunge in TAIFEX night-session futures, Taiwan stocks on October 30 opened down 228.54 points at 46139.79 points. Subsequently, under broad weakness in major heavyweights such as 台積電 and 台達電, high-priced thousand-dollar stocks, and AI and semiconductor-related groups, the index moved lower during the session, falling to an intraday low of 44726.26 points, down 1652.07 points, and losing the 45,000-point mark. Buying emerged at lows, but follow-through was insufficient. The加權指數 closed at 45211.83 points, down 1156.50 points, or 2.49%, falling below the six-month moving average, with turnover reaching 877.7 billion New Taiwan dollars.
Heavyweight Electronics Stocks Under Pressure Across the Board
Among heavyweights, 台積電 fell 45 yuan to close at 2370 yuan, down 1.86%; 聯發科 plunged 130 yuan to close at 3915 yuan, down 3.21%; 台達電 fell directly to limit-down to close at 1335 yuan; 鴻海 fell 2.5 yuan to close at 245.5 yuan; 日月光投控 fell 15 yuan to close at 668 yuan. In addition, 台光電 fell 6.69%, 欣興 fell 4.9%, and 聯電 fell 3.46%, with electronic heavyweights almost entirely under pressure. Among listed sector indices, gainers were few and losers many, with the electronic components sector plunging 6.46%, the optoelectronics sector falling 6.34%, and the petrochemicals sector falling 4.25%, becoming the heaviest selling pressure on the market.
Shipping and Food Buck the Trend to Close Higher
Only a few sectors including shipping, food, trade and department stores, and cement closed higher against the trend, with the 中航運 sector up 1.93%, leading gainers, food up 0.89%, and trade and department stores up 0.67%. Shipping stocks became a safe haven for funds, driven by the countdown to European and U.S. port strikes and tensions in the Middle East, with 長榮 and 萬海 both surging over 4%, and 裕民 and 陽明 also rising over 2%. Food stocks were led by 味全 surging to limit-up, with 味王, 大成, 統一 and 宏亞 closing higher together; 統一超 in the trade and department store sector rose over 1% on record-high third-quarter revenue and profit for the period, showing defensive resilience.
Selling Pressure Spreads Across AI Supply Chain
AI concept stocks faced across-the-board profit-taking, with none of the 46 thousand-dollar stocks spared, including 致茂 and 台達電 hitting limit-down, and another 24 falling over 5%. In the PCB group, 欣興 and 南電 fell over 4%; passive components leader 國巨 plunged over 7%, while 鈺鎧 and 華新科 hit limit-down; in the silicon wafer group 台勝科 hit limit-down, while 環球晶, 嘉晶 and 昇陽半導體 fell over 7%; memory stocks 南亞科, 華邦電, 力積電, 旺宏 and 群聯 fell over 3% together. In addition, IC packaging and testing stocks including 超豐, 京元電, 欣銓 and 力成 fell over 5%, optical communications stock 群光環 hit limit-down, 聯亞, 全新, 前鼎 and 環宇-KY fell over 7%, and petrochemical stock 南亞 with AI themes also plunged over 5%, showing selling pressure spreading from heavyweights to the entire AI supply chain. According to statistics, listed and over-the-counter stocks totaled 18 limit-up stocks, including 科妍, 冠西電, 和暢科技, 全景軟體 and others.
