"The Fund underperformed in 2025 as deep-value holdings and life sciences investments dragged down solid gains from its AI and durable growth compounders. The managers responded with active portfolio cleanup, exiting CarMax and fully valued names while maintaining conviction in a 2026 cash-flow turnaround at Liberty Broadband."
In 2025, the Partners III Opportunity Fund's Institutional Class returned +3.17%, underperforming the Bloomberg U.S. 3000 Index's return of +17.21%. Although the fund's 'AI Winners' (Alphabet, Microsoft, Amazon, Meta) and other durable compounding businesses (Berkshire Hathaway, Visa, Mastercard) performed respectably, performance was dragged down by a 'lost year' in its life sciences holdings and significant declines in its 'deep value' positions, notably CarMax and Liberty Broadband. In response, the managers completely exited CarMax due to deteriorating operating conditions and competitive headwinds, and closed fully valued positions in Labcorp and Perimeter Solutions. They maintained their holding in Liberty Broadband, anticipating a peak in capital expenditure in 2025 and improved free cash flow dynamics starting in 2026. The fund ended the year with a net long position of 93%.
