Taiwan's benchmark stock index came under heavy selling pressure on the 11th, falling more than 900 points to an intraday low of 45,997 and breaking below the psychologically important 46,000 level. Electronics, financial and traditional-industry shares declined together, while trading volume stood at about NT$720 billion, or approximately $22.8 billion, around 10 a.m. International pressure intensified as oil prices moved above $100 a barrel, U.S. Treasury yields approached 5%, all four major U.S. indexes closed lower on Thursday (the 10th), and the Philadelphia Semiconductor Index fell 2.66%. TSMC dropped to NT$2,410, while several major technology companies declined between 1% and 7%. Financial shares and Nan Ya Plastics also weakened. Decliners outnumbered advancers by more than 4-to-1, reflecting broad profit-taking rather than a single-sector retreat. The index had already fallen 242.87 points on Wednesday (the 10th) to 46,940.49, bringing its two-session decline to more than 1,100 points. Analysts cited Middle East tensions, higher oil prices, weaker Apple shares after its product launch event, rising U.S. yields and uncertainty over inflation data and next week's Federal Reserve interest-rate decision. A break below monthly moving-average support could expose the quarterly moving average, although shrinking volume suggests panic selling has not emerged. Market participants expect international factors to remain decisive while investors focus on capital management and risk control.
