Why super-investors own WRB
Ownership of WRB within the tracked cohort is narrow and stable: three managers hold a combined $113M, with Joel Greenblatt accounting for the bulk at $92M — though that represents just 0.1% of his portfolio. Bruce Berkowitz carries the highest conviction at 1.1% of his book ($17M), while Thomas Gayner holds a token $4M position. Activity in 2026Q1 was nonexistent — no new entrants, no additions, no trims, no exits. The cohort owner count has sat at a steady one-to-three-manager range for eight consecutive quarters, suggesting neither growing enthusiasm nor imminent capitulation. Interest here is best characterized as dormant rather than building.
