- The Taiwan Weighted closed at 43,091.87 on November 12, down 2.63 percent from the previous session.
- Semiconductor shares led the decline after Nvidia fell sharply in after-hours trading amid reports about its chief executive.
- TSMC dropped 2.30 percent and contributed about 440 points to the index decline, according to CNA.
The Taiwan Weighted index, or TAIEX, closed sharply lower on Thursday, November 12, as weakness in semiconductor stocks ended the market's rebound from the previous session. The benchmark fell 1,165.28 points, or 2.63 percent, to 43,091.87, according to Focus Taiwan, citing Central News Agency. Turnover reached NT$1.01 trillion.
Nvidia uncertainty weighs on Taiwan
The index traded above its previous close for much of the morning before turning lower around midday, with losses accelerating later in the session. It moved between 42,943.50 and 44,525.24 points, according to CNA.
The immediate pressure came from technology stocks after Nvidia shares fell by about 8 percent in after-hours trading. Investors were concerned that weakness in the leading artificial-intelligence chip designer could spread to other AI-related companies when US markets opened, CNA reported. A separate Reuters report published by the Fort Worth Star-Telegram also linked the broader Asian technology sell-off to reports that Nvidia's board was considering whether to remove CEO Jensen Huang.
Large-cap electronics lead losses
Large-cap electronics shares were the main drag on the index. Taiwan Semiconductor Manufacturing Co. fell 2.30 percent to NT$2,340.00 and contributed about 440 points to the TAIEX's decline, according to CNA. MediaTek dropped 3.51 percent to NT$3,850.00, while ASE Technology Holding lost 5.02 percent to NT$586.00. Nanya Plastics declined 3.68 percent to NT$379.50.
TSMC's weight made its move particularly significant: CNA said the contract chipmaker represents more than 40 percent of the market's total capitalization. Selling also reached other semiconductor and AI-server names, underscoring the index's sensitivity to changes in sentiment toward the global technology supply chain.
Defensive stocks offer limited support
Some investors shifted toward selected defensive sectors during the sell-off. Uni-President Enterprises rose 1.43 percent, Great Wall Enterprise gained 2.62 percent, Taiwan Mobile advanced 0.78 percent and Chunghwa Telecom added 0.62 percent, CNA reported. Their gains were not sufficient to offset declines in the heavily weighted electronics segment.
Foreign institutional investors were net sellers of NT$684.50 million on the main board, according to the Taiwan Stock Exchange data cited by CNA. The result leaves the TAIEX 1,165.28 points below Wednesday's close of 44,257.15, when it had gained 1,545.23 points, or 3.62 percent. Investors will now assess whether the technology-led retreat remains concentrated in Nvidia-linked stocks or broadens across the wider market. Further coverage is available on the TAIEX topic page.
