- TSMC fell 2.30% and accounted for about 440 points of the index decline, according to Focus Taiwan.
The Taiwan Weighted index ended Thursday's session sharply lower as selling in semiconductor and other large-cap technology stocks intensified. The benchmark closed at 43,091.87, down 1,165.28 points, or 2.63%, on November 12, 2026.
Focus Taiwan, citing the Central News Agency, reported that the index traded above the previous close for much of the morning before turning lower around noon. The session range was 42,943.50 to 44,525.24, while turnover reached NT$1.01 trillion.
Technology shares drive the retreat
TSMC reversed earlier gains to finish 2.30% lower at NT$2,340.00. Focus Taiwan reported that the company, which represents more than 40% of the market's total capitalization, contributed about 440 points to the TAIEX decline. MediaTek fell 3.51% to NT$3,850.00, Nanya Plastics lost 3.68% to NT$379.50, and ASE Technology Holding dropped 5.02% to NT$586.00.
Hon Hai Precision Industry was comparatively resilient, declining 0.83% to NT$240.00. Investors also moved toward selected defensive shares: Uni-President Enterprises gained 1.43%, Great Wall Enterprise rose 2.62%, and Chunghwa Telecom added 0.62%, according to the same report. The financial sector edged down 0.05%.
Nvidia news weighs on sentiment
The immediate pressure came from the global technology complex. Reuters, published by the Fort Worth Star-Telegram, reported that Nvidia shares fell 8.8% in extended trading after reports that the company's board was considering whether to remove CEO Jensen Huang. Reuters said the news weighed on chip stocks across Asia, with Taiwan's benchmark among the region's major decliners.
Focus Taiwan quoted equity analyst Tsai Ming-han as saying that investors feared weakness in Nvidia could spread to other artificial-intelligence-related stocks when US markets opened. That backdrop helps explain the concentration of the TAIEX decline in large electronics companies, although it does not establish a direct one-to-one relationship between the news and every index component.
Foreign institutional investors sold a net NT$684.50 million of shares on the main board, according to the Taiwan Stock Exchange data cited by Focus Taiwan. The next session's direction will likely remain sensitive to developments in global technology shares and investor assessments of AI-related valuations.
