Why super-investors own ULS
Henry Ellenbogen is the dominant force here, holding ULS at 2.9% of his portfolio — a $282M position that accounts for nearly 89% of the cohort's combined $318M stake. He added to the position in 2026Q1, reinforcing what is already a high-conviction holding. Joel Greenblatt holds a negligible slice at roughly $36M. Cohort breadth has been flat at one or two owners for at least eight quarters, suggesting this remains an Ellenbogen-specific thesis rather than a broadly recognized super-investor idea. With no new entrants and no exits, interest is neither expanding nor fading — it is effectively a one-manager story, sustained by Ellenbogen's continued accumulation.
