TSMC Breaks NT$2,500 as Taiwan Stocks Set Records

TSMC (2330) is the largest stock by weighting in Taiwan’s equity market and a critical supplier of advanced manufacturing processes for global AI chips, giving its shares significant influence over the broader index. Its ADRs have long traded at a premium to its Taipei-listed shares because they are easier for foreign investors to trade and are included in indexes. The narrowing gap suggests domestic investors, including retail buyers and local investment trusts, are gaining pricing influence. It also reflects stronger market confidence in revenue growth across the AI supply chain.

Bloomberg data showed TSMC’s average ADR premium fell to 13.7% in May 2026 from 26% in December 2025, marking a fifth consecutive monthly decline and a two-year low. On June 2, TSMC rose NT$25 to a record close of NT$2,380, pushing Taiwan’s benchmark stock index to a record close of 45,557.31. Its Taipei-listed shares have gained more than 50% this year, outpacing the ADRs’ nearly 40% advance.

TSMC is the largest stock in Taiwan’s equity market by weighting and a linchpin of the global advanced-process and AI chip supply chains. Strong earnings and share-price gains at NVIDIA and AMD prompted investors to raise their semiconductor demand forecasts. The value of the National Development Fund’s TSMC stake also moved closer to NT$4 trillion, benefiting related funds and ETFs.

TSMC (2330) jumped to NT$2,345 a share at the open on July 20, 2026, setting a record high and lifting the Taiex by nearly 1,000 points intraday. The index broke through the psychologically important 42,000-point threshold for the first time. MediaTek, meanwhile, bucked the rally and fell after excessive short-term gains prompted its designation as a disposition stock, restricting trading.

TSMC’s advanced manufacturing technology and global demand for AI chips have made it the main force behind Taiwan’s stock market rally past 40,000 points. The Financial Supervisory Commission is also advancing the “TSMC clause,” which eases limits on ETFs’ holdings of a single stock. The change reduces regulatory obstacles for funds tracking large index heavyweights, making passive inflows an important source of market support.

TSMC shares recently reached a record high and are moving toward NT$2,330 apiece, helping the weighted index break above 40,000 points. The impact of ETF portfolio adjustments continues to build. The market will look to corporate fundamentals and earnings data due in May to gauge whether the rally fueled by AI enthusiasm and passive buying can continue.

Taiwan’s latest equity rally has been led by artificial intelligence server and semiconductor stocks. Taiwan Semiconductor Manufacturing Co. (TSMC), the market’s largest constituent by capitalization, has an outsized influence on the benchmark index. Foreign investors’ purchases of Taiwanese shares and accompanying capital inflows also support the Taiwan dollar. The simultaneous gains in stocks and the currency reflect international investors’ confidence in Taiwan’s technology supply chain.

AI stocks rebounded on the 25th, while a sharp rise in TSMC shares drove the benchmark index above 35,000 points to an all-time high. Foreign capital poured in at the same time, pushing the Taiwan dollar up by about NT$0.15 against the U.S. dollar intraday. It closed NT$0.121 stronger at NT$31.34 per U.S. dollar, returning to the NT$31.3 level and reaching a nearly one-month high.
