Why super-investors own AMG

Ownership of AMG within this cohort is narrow and stable, with three managers holding a combined $364M but the story concentrated almost entirely in one name: John Rogers, whose $294M position represents 3.3% of his portfolio — by far the highest conviction here. Joel Greenblatt holds $68M but at a negligible portfolio weight, and Mason Hawkins carries just $2M. The cohort count has sat at a consistent one core holder for eight consecutive quarters (Rogers), with Hawkins and Greenblatt as peripheral participants. There was zero activity in 2026Q1 — no adds, trims, new entrants, or exits — suggesting neither growing enthusiasm nor deteriorating conviction across the group. Interest is neither rising nor fading; it is essentially static.
