The most intriguing discovery is Sunbelt Rentals Holdings Inc. (SUNB) at 0.38% portfolio weight across 10 super investors, representing a $28 billion market cap company that completed its NYSE listing in March 2026. According to Dataroma analysis, every single holder is currently buying, with Dorsey Asset Management leading at 11.43%, Ruane Cunniff LP at 5.93%, and Dodge & Cox Funds holding the largest dollar position at approximately $3.5 billion. The stock has declined 15% since its March debut, yet shows unanimous conviction among value-oriented investors.
As reported by Dataroma, the analysis reveals that 13F filings are already up to 45 days stale by the time they're public, making direct portfolio replication potentially problematic. The data suggests that while mega-caps like Microsoft and Meta show split buying patterns among super investors, smaller companies like Sunbelt Rentals demonstrate unusually fast and unanimous conviction. The list provides a filtered starting point for retail investors, offering names that have undergone rigorous due diligence by institutional capital allocators, though investment strategies should align with individual risk appetite and time horizons rather than replicating institutional positions directly.
