Digest Analysis

Quick Take

"Weitz's value-focused fund underperformed in 2025 despite strong AI holdings led by Alphabet's Gemini breakthrough. Life sciences and deep value positions dragged returns."

Executive Summary

The Partners III Opportunity Fund returned 0.67% in Q4 2025 and 3.17% for the year, underperforming the Bloomberg US 3000 Index's 17.21% annual return. The fund benefited from AI Winners including Alphabet, Microsoft, Amazon and Meta Platforms, which averaged 16% of assets and delivered strong returns led by Alphabet's Gemini AI breakthrough. Payment networks and insurance holdings also contributed positively. However, the portfolio was weighed down by life sciences investments facing research budget pressures and deep value positions that struggled despite cheap valuations. The managers sold CarMax due to a challenging used vehicle environment and competitive pressures, while maintaining Liberty Broadband based on Charter's improving free cash flow outlook as network upgrade spending peaks. The fund closed positions in Labcorp and Perimeter Solutions at target valuations and ended the quarter 93% net long. The managers remain committed to their value-oriented, contrarian approach while adapting to changing fundamentals.
