TSMC's Stock Soars: A Challenge for Global Fund Managers

Stocks Nov 15, 2025

The surge in TSMC’s stock has left global fund managers on their toes, scrambling to keep up while bound by regulatory constraints. A staggering 36% rise this year alone has shifted the dynamics within the financial world, demonstrating TSMC’s weight and influence. The chipmaking giant, dominating significant portions of major stock indexes, has put a spotlight on the limitations that fund managers face.

TSMC’s Unprecedented Influence

Dominating nearly 43% of Taiwan’s Taiex index and holding significant portions in the MSCI Emerging Markets and Asia Pacific Excluding Japan Indexes, TSMC’s footprint is undeniable. According to CoinCentral, this has forced even large financial entities to rethink their strategies, bringing attention to how regulatory limits can sometimes stifle potential growth.

The legal cap restricting any single stock’s stake to 10% of a portfolio has become a significant hurdle. For Roxy Wong at BNP Paribas, the constraint isn’t about choice but necessity.

“We’re consistently underweight TSMC, not because of conviction, but due to structural limits,” Wong mentions.

This growing weight in stock indices beyond the cap continues to spiral upwards, making everything else in comparison seem stagnant.

New Horizons for Fund Managers

Faced with these constraints, fund managers have turned creative. Many are leveraging derivatives such as options or futures to retain some form of association with TSMC’s rising value. Others are pivoting to indirect actors within TSMC’s supply chain, hoping to replicate the stock’s robust trajectory. However, as John Tsai of Eastspring Investments notes, mimicking TSMC’s unique market combination remains challenging.

The Debate Over Regulatory Adaptation

As hints of conversations about relaxing regulatory restrictions begin to surface in Taiwan, uncertainty looms. While the financial environment evolves, so too must the regulations that seek to guide it. Investors and portfolio managers watch closely, advocating for flexibility that meets modern market demands without sacrificing security.

A Continual Balancing Act

In this landscape, TSMC’s success is both a boon and a conundrum. Its stock continues to attract global attention, embodying the tech sector’s spirit and potential. As strategic movements unfold and companies adjust, TSMC remains a testament to the power one corporation can exert within global markets—a tale of equilibrium, ingenuity, and adaptation in a world of fiscal flux.
