TSMC's 'Mountain-Building Movement': Retail Investor Base Surges by 1 Million, Ownership Exceeds 1%

TSMC, often called Taiwan's "guardian mountain," is experiencing a "mountain-building movement" as more than a million retail investors have bought into the chip giant in the past year, driven by the global AI wave.

Data from the Taiwan Depository & Clearing Corporation shows TSMC's total shareholder accounts surged to 2.835 million by June 18, an increase of 1.153 million from the previous year. The most dramatic growth came from "small" shareholders holding fewer than 1,000 shares, whose numbers ballooned by over 1 million to 2.306 million, an 88.5% increase.

As the AI wave sweeps the globe, this "guardian mountain" of Taiwan has evolved into a national "mountain-building movement," attracting over a million retail investors in just one year.

This influx means that 94% of new TSMC shareholders over the past year acquired their stakes through fractional shares. Currently, one in five Taiwanese shareholders reportedly holds TSMC fractional shares. However, this "ant army" of small investors collectively owns only 1.03% of the company, a slight increase from 0.69% last year. In contrast, 1,484 large shareholders or institutional investors, representing just 0.05% of total accounts, control a commanding 85.22% of TSMC's equity.

The "M-shaped" distribution of TSMC's shareholding is becoming more pronounced. While the number of small shareholders has exploded, their overall stake remains minimal, highlighting the significant concentration of ownership among a few major players.
