December 2025 Recap

Strong month for managers focused on small caps, financials, and Europe

The disclosed holdings of our Small Cap, Financials, and Europe groups had strong performance in December. Managers focused on China, Brazil and India had a tough month, down more than 2%. After a strong 6+ month run, our Biotech group retreated slightly, down 1% in December. For the full year 2025, the disclosed holdings of our Biotech group remained among the strongest performers, only slightly trailing our Brazil group.

As a reminder, the table below is based on our “OWL Groups” – curated lists of over 500 managers frequently found in leading allocators’ portfolios. These lists are categorized by geography, sector, and style, enabling our users to easily monitor groups of managers and their underlying disclosed holdings. All returns shown are estimates based on publicly disclosed holdings.

OWL users received a detailed list of estimated manager performance on Friday. As we’ve noted in prior months, Carvana was a big driver of returns on our best performing list, with the stock up 10% in December. Carvana comprises 81% of CAS’s portfolio, 69% of Camelot’s portfolio, and 38% of Spruce House’s portfolio. As a reminder, MIT is invested in all three of those managers.

AST SpaceMobile was also a driver of returns for several managers on the list, including Broad Run (38% of its portfolio) and Once Capital Management (15% of its portfolio), with the stock up 28% in December and 235% in 2025. AST SpaceMobile is building a space-based cellular broadband network that can extend 4G/5G coverage to places with little or no cell service.
