In a significant move, William Von Mueffling's Cantillon Capital Management drastically reduced its stake in Taiwan Semiconductor Manufacturing (TSM) by 95.4% during the second quarter of 2026. According to regulatory filings, this disclosure is based on trades made by June 30, 2026, and made public on July 29, 2026. The firm sold an estimated 2.38 million shares, cutting its position from 2.49 million shares down to just 114,820.
This substantial sale was part of a broader, uniform reduction of approximately 95% across all of Cantillon's positions. This pattern suggests the move was likely driven by a structural event, such as a large client redemption or an asset reallocation, rather than a fundamental change in outlook on TSM itself. The chipmaker reported strong Q2 earnings and raised its full-year revenue guidance, citing high demand from the AI and HPC sectors.
