Why super-investors own UNP
Seth Klarman dominates the cohort's UNP exposure, with a 7.3% portfolio allocation worth $374M that dwarfs every other holder's conviction — including Bill Nygren, whose $918M position is the largest in dollar terms but represents just 1.2% of his portfolio. Eleven super-investors hold the stock collectively at $1.5B, though cohort count has been range-bound at 3–4 for most of the past two years after a brief dip to two. Activity in 2026Q1 was minimal: Daniel Loeb trimmed his comparatively modest $24M position, and no manager added or initiated. The overall picture is one of stable, low-turnover ownership concentrated in a handful of long-duration holders, with no meaningful signs of either building enthusiasm or accelerating exits.
