The Taiwan Weighted (TAIEX) ended Thursday's session on November 12, 2026, at 43,091.87 points, according to Focus Taiwan. The index lost 1,165.28 points, equivalent to 2.63%, compared with Wednesday's close of 44,257.15.
Technology shares drive decline
The index traded above the previous closing level for much of the morning before turning lower around noon, with selling accelerating later in the session. The TAIEX moved between 42,943.50 and 44,525.24 points, while turnover reached approximately NT$1.01 trillion.
Focus Taiwan, citing market dealers, said sentiment was hurt by an approximately 8% decline in Nvidia shares in after-hours trading. Investors were concerned that weakness in the U.S. chip designer could spread to other artificial-intelligence-related companies when U.S. markets opened. Dealers also pointed to reported controversy involving Nvidia chief executive Jensen Huang as a factor behind the more cautious tone. These comments describe the market explanation reported by dealers and do not establish a separate causal measure for the index move.
TSMC weighs on the benchmark
Large-cap electronics stocks led the decline. Taiwan Semiconductor Manufacturing Co. fell 2.30% to NT$2,340.00 and contributed approximately 440 points to the TAIEX decline, according to the same report. MediaTek dropped 3.51%, Nanya Plastics lost 3.68% and ASE Technology Holding fell 5.02%.
Some defensive sectors performed better. Uni-President Enterprises rose 1.43%, Great Wall Enterprise gained 2.62%, Taiwan Mobile added 0.78% and Chunghwa Telecom advanced 0.62%. The financial sector edged down 0.05%.
Market context for investors
The decline followed a gain of 1,545.23 points, or 3.62%, on November 11. Foreign institutional investors sold a net NT$684.50 million on the main board on Thursday, according to the report. The sharp reversal underlines the benchmark's sensitivity to global semiconductor sentiment after its recent technology-led gains.
