Why super-investors own CME
Ownership within the cohort has been stable but narrow — five managers hold CME, with no additions, trims, or exits recorded in 2026Q1, and the owner count has been flat at three for six consecutive quarters before ticking up to five. The two largest holders drive the bulk of exposure: William Von Mueffling holds $409M (2.7% of portfolio) and John Armitage carries $349M at 3.9% concentration, the highest in the cohort. Joel Greenblatt, Thomas Gayner, and Lindsell Train each hold sub-0.2% positions. The complete absence of activity this quarter — no new entrants, no sizing changes — suggests the cohort views CME as a mature, hold-steady allocation rather than an active opportunity.
