TLDR
- Taiwan’s financial authorities increased the individual stock investment ceiling for domestic funds from 10% to 25%
- Taiwan Semiconductor is the sole stock eligible under the new rule, representing over 40% of Taiwan’s stock market
- Shares of TSMC in Taiwan climbed 5% to reach an all-time high of NT$2,185
- The semiconductor giant revealed its A13 process technology and confirmed plans for an Arizona packaging plant by 2029
- U.S. ADRs (TSM) advanced 3.3% to $395.49 during premarket hours, continuing to trade above local share prices
Shares of Taiwan Semiconductor Manufacturing Company surged to an unprecedented level in Taiwan on Friday, propelled by a significant regulatory adjustment from financial authorities and announcements regarding cutting-edge chip innovations and American manufacturing expansion.
Taiwan’s Financial Supervisory Commission increased the maximum allocation that domestic equity funds and actively managed ETFs can hold in a single listed company — lifting the threshold from 10% to 25%. The qualification: this new limit applies exclusively to companies representing more than 10% of the Taiwan Stock Exchange’s total capitalization.
Taiwan Semiconductor stands alone in meeting this criterion. The chipmaker represents more than 40% of Taiwan’s entire stock market capitalization.
Taiwan Semiconductor Manufacturing Company Limited, TSM
Shares trading in Taiwan surged 5% to close at NT$2,185, marking a new all-time high.
American Depositary Receipts advanced 3.3% to $395.49 during Friday’s premarket session. Since each ADR represents five underlying shares, this translates to an implied value of approximately $79.10 per individual share.
This valuation exceeds what local investors in Taiwan paid. A consistent pricing differential has existed between TSMC’s Taiwan-listed shares and its ADRs, which typically command a premium due to greater accessibility for global investors. The regulatory adjustment announced Friday could potentially reduce this valuation gap going forward.
Taiwan Semiconductor Reveals A13 Process Technology
The favorable regulatory development wasn’t the sole catalyst behind the stock’s rally. Earlier this week, TSMC introduced an advanced generation of semiconductor manufacturing processes engineered to create smaller, quicker, and more power-efficient chips.
The chipmaker’s A13 process node — approximately a 1.3-nanometre-class technology — represents an enhancement of its previous A14 platform. According to TSMC, it provides roughly 6% greater transistor density and enhanced power efficiency, while maintaining compatibility with current chip architectures.
These advanced process nodes target sophisticated AI and high-performance computing markets, sectors where customer demand continues to grow robustly.
Arizona Chip Packaging Facility Scheduled for 2029 Launch
TSMC additionally revealed expanded American production initiatives. The semiconductor manufacturer confirmed plans to establish an advanced chip packaging operation in Arizona scheduled to begin operations by 2029.
This facility will handle CoWoS packaging operations and 3D chip integration — both technologies that have become essential for the sophisticated processors powering artificial intelligence applications.
Advanced packaging has emerged as a constraint in the AI hardware supply chain, and the Arizona location is designed to alleviate this bottleneck while simultaneously strengthening TSMC’s American manufacturing presence.
Taiwan Semiconductor currently has multiple wafer fabrication plants under development in Arizona. Adding packaging capabilities would provide the company with more comprehensive end-to-end manufacturing operations in the United States.
TSMC’s ADRs traded up 3.3% at $395.49 during Friday’s premarket session.
