Taiwan Stocks Plunge Over 1000 Points as Over 1200 Companies Fall

Taiwan's stock market, often referred to as the "Great Taiwan Rollercoaster," experienced a sharp decline on Wednesday, with more than 1200 companies seeing their stock prices fall. The main index plummeted over 1000 points, reflecting a broad market sell-off.

The downturn was triggered by a combination of factors, including a slump in US tech stocks and concerns over potential Taiwanese government regulations on semiconductor exports to China. Major tech giants and semiconductor companies, including TSMC, UMC, and MediaTek, opened lower, dragging the index down significantly.

Initially, the index fell 122.99 points to open at 44581.45. The decline accelerated as popular stocks in semiconductors, memory, ABF substrates, IC design, and AI sectors all experienced widespread drops. Even the financial sector, which had shown strength the previous day, saw a downturn.

Despite a brief recovery attempt, with some sectors like optoelectronics and communication networks showing upward movement and certain stocks like UMC and Winbond turning positive, investor sentiment soured. High-priced stocks led the sell-off, causing the index to drop 519 points and test the 44185 level. Ultimately, the market continued its downward trend, with the index falling 1060 points to a low of 43644, breaking below the 44,000 mark.

The broader market context included a decline in the S&P 500 and Nasdaq on Tuesday, influenced by US President Trump's remarks about responding to Iran's downing of a US helicopter. The Philadelphia Semiconductor Index also fell 1.93%, though TSMC's ADR saw a slight increase.
