In a recent 13F filing with the SEC, investment manager Dodge & Cox revealed a substantial increase in its holdings of Taiwan Semiconductor Manufacturing Co., Ltd. (TSM). The filing, which reflects the firm's portfolio as of June 30, 2026, shows an increase of over 1200% in their TSM shares, growing from 107.80K to 1.44M. This raised the total value of their position from $36.43M to $688.07M.

As with all 13F filings, this information is on a delay and represents a snapshot of the portfolio at the end of the second quarter. During that period, TSM reported strong earnings, driven by high demand for its advanced chips, particularly for AI applications. The increased investment has raised Dodge & Cox's portfolio weight in the semiconductor giant from 0.02% to 0.36%.
