TAIPEI, June 19, 2026, 02:04 (CST)
- The Taiex finished at a record 46,465.20 on Thursday in Taiwan. TSMC gained 1.05% to NT$2,410. Markets are now shut for the Dragon Boat Festival break.
- TSMC’s U.S. ADR rose 6.3% to $459.24 in Thursday afternoon New York trading, pushing chip stocks higher for the week.
- Investors are watching to see if the semiconductor rally keeps up after holidays in the U.S. and Taiwan, with attention also on any new info about Intel’s move on Apple and TSMC’s Arizona packaging expansion.
Taiwan Semiconductor Manufacturing Co. headed into the Dragon Boat Festival holiday trading at record highs in Taipei. Its U.S.-listed ADR kept moving higher too, with buyers staying focused on AI chip-linked shares.
The timing is key since TSMC makes up over 40% of Taiwan’s market cap. Its rise on Thursday put about 200 points on the Taiex benchmark, according to Focus Taiwan.
Taipei markets are closed Friday, June 19, for Dragon Boat Festival. U.S. exchanges also won’t trade because of Juneteenth. That leaves the latest move as a holiday-shortened week summary: TSMC’s ADR went from $423.93 on June 12 to $459.24 in late New York trade, up about 8%.
Chip stocks drove Wall Street gains on Thursday. The Philadelphia Semiconductor Index rose 6.3% and closed at a record high. Intel jumped after U.S. President Donald Trump said Apple would work with Intel on U.S. chip design and manufacturing, according to Reuters.
Tech stocks in Taipei tracked gains in the U.S., even with the Federal Reserve’s hawkish stance, Cathay Futures Consultant analyst Tsai Ming-han said. “Sound fundamentals during the current AI boom continued to push up the bellwether electronics sector and the Taiex,” Tsai said. He expects buying in TSMC to go on. Focus Taiwan – CNA English News
Capacity is the main story. TSMC CEO C.C. Wei said this month that “customer demand is so high” and the company is “doing our best to ensure TSMC does not become a bottleneck.” He pointed straight to the risk that chip supply could lag AI demand. Reuters
TSMC is expanding its U.S. supply chain. The company and Amkor Technology have signed a 10-year deal for TSMC to buy advanced packaging and testing services from Amkor’s Arizona site. Advanced packaging refers to connecting chips together after fabrication for better speed and efficiency. Kevin Zhang, TSMC senior vice president and deputy co-chief operating officer, said both firms have worked together in advanced packaging for years. Amkor CEO Kevin Engel called the agreement a step toward a complete U.S. supply chain from wafer production to packaged and tested chips.
Intel’s position in the chip race looks tougher after the Intel news. Reuters said an Apple deal could help Intel catch up to TSMC, the top contract chipmaker. Neither Apple nor Intel gave Reuters a comment, and Trump did not say which chips Intel would produce.
This isn’t a sure bet. If Intel shows it can land and deliver big Apple business with decent yields, the odds go up for tougher U.S. foundry competition. TSMC also has its own limits in Taiwan—Wei said last week it still doesn’t have enough talent, with water supply also a worry for the island’s chip makers.
No headline TSMC sales data is expected this week, with the next revenue update set for July 10 on the company’s posted calendar. That leaves TSMC shares moving on outside triggers—rate moves, U.S. chip sentiment after Juneteenth, action in Intel, and market reaction to the Amkor deal. Investors will watch to see if the Amkor news shows TSMC’s U.S. plans turning into real production.
