TLDR
- Taiwan’s financial regulator raised the single-stock investment limit for local funds from 10% to 25%
- TSMC is the only stock that qualifies, making up over 40% of the Taiwan Stock Exchange
- Taiwan-listed TSMC stock rose 5% to a record NT$2,185
- TSMC also unveiled its A13 chip node and announced an Arizona packaging facility opening by 2029
- The ADRs (TSM) rose 3.3% to $395.49 in premarket trading, but trade at a premium vs. local shares
TSMC’s Taiwan-listed stock hit a record high on Friday, pushed higher by a rule change from Taiwanese regulators and fresh news on chip technology and U.S. expansion.
$TSM laid out its process roadmap through 2029 and still doesn’t plan to use $ASML High-NA EUV over that time.
Roadmap details:
• New client chip node every year
• New AI/HPC node every two years
• Added A12, A13 and N2U to the lineup pic.twitter.com/IKcDwg6MDw— Shay Boloor (@StockSavvyShay) April 23, 2026
Taiwan’s Financial Supervisory Commission raised the cap on how much local equity funds and actively managed ETFs can put into a single listed stock — from 10% to 25%. The catch: the rule only applies to stocks that make up more than 10% of the Taiwan Stock Exchange.
TSMC is the only company that clears that bar. Its stock accounts for more than 40% of the Taiwan market by value.
Taiwan Semiconductor Manufacturing Company Limited, TSM
Taiwan-listed TSMC stock jumped 5% to NT$2,185, a record closing high.
U.S.-listed ADRs climbed 3.3% to $395.49 in premarket Friday trading. Each ADR represents five ordinary shares, putting the implied value of a single share at around $79.10.
That’s still higher than what investors in Taiwan paid. A persistent gap has long existed between TSMC’s local shares and its ADRs, which often trade at a premium because they’re easier for international investors to access. Friday’s regulatory change may help narrow that gap over time.
TSMC Unveils A13 Chip Node
The regulatory tailwind wasn’t the only thing driving the stock. On Wednesday, TSMC also unveiled a new generation of chipmaking processes designed to produce smaller, faster, and more efficient semiconductors.
The company’s A13 node — a roughly 1.3-nanometre-class process — is a refinement of its earlier A14 technology. TSMC says it delivers about 6% higher transistor density and improved efficiency, while staying compatible with existing chip designs.
The new nodes are aimed at advanced AI and high-performance computing applications, areas where demand from major customers remains strong.
Arizona Packaging Plant Planned for 2029
TSMC also outlined fresh U.S. manufacturing plans. The company said it intends to open an advanced chip packaging facility in Arizona by 2029.
The facility will support CoWoS packaging and 3D chip integration — two technologies that have become critical for the complex processors used in AI systems.
Chip packaging has become a bottleneck in the AI supply chain, and the Arizona site is positioned to help ease that pressure while also expanding TSMC’s footprint on U.S. soil.
TSMC already has wafer fabrication facilities under construction in Arizona. The addition of packaging capability would give the company a more complete manufacturing presence in the country.
TSMC’s ADRs were up 3.3% at $395.49 in Friday premarket trading.
