Unpacking Tweedy Browne's Latest Investment Moves
Tweedy Browne's Portfolio Overview in Q4 2025: A Deep Dive into Key Holdings
In the fourth quarter of 2025, Tweedy Browne's 13F portfolio witnessed a significant increase, reaching an impressive total value of $1.24 billion. A notable change in this period was Ionis Pharmaceuticals, which emerged as the largest holding, now constituting a substantial 15.74% of the entire portfolio. This shift indicates a strong conviction in the pharmaceutical sector and particularly in Ionis's future prospects.
Major Portfolio Adjustments: Increases, Reductions, and New Entrants
During this quarter, Tweedy Browne strategically increased its stake in CNH Industrial, signaling a positive outlook on the company's performance and market position. Conversely, the firm substantially reduced its holdings in both Ionis (despite it becoming the largest position, indicating a rebalancing after prior heavy investment) and Alphabet, suggesting a cautious approach or profit-taking in these high-profile companies. Furthermore, Tweedy Browne initiated a new position by investing in UniFirst Corp., introducing a fresh asset to its diverse portfolio. Concurrently, the firm nearly exited its investment in FMC Corporation, following aggressive divestment activities in previous quarters, which reflects a strategic shift away from this sector.
Concentrated Conviction: The Dominance of Top Holdings
The firm's investment philosophy is clearly demonstrated by the concentrated nature of its top five holdings. Ionis Pharmaceuticals (IONS), CNH Industrial (CNH), Berkshire Hathaway Class B (BRK.B), Coca-Cola Femsa (KOF), and Alphabet (GOOGL) collectively account for approximately 58% of the total portfolio. This high concentration underscores Tweedy Browne's high-conviction approach, where significant capital is allocated to a select group of companies that the firm believes offer the most promising long-term value and growth potential.
