Why super-investors own MX

Interest in MX within this cohort is minimal and static. Three managers — Howard Marks, Prem Watsa, and Joel Greenblatt — hold a combined $9M, though the position count history shows just one owner across the prior seven quarters, suggesting two of these are very recent additions or reclassifications. Marks accounts for nearly all the capital at $8M, representing 0.1% of his portfolio — the highest concentration in the cohort but still a negligible allocation. No one added, trimmed, started, or exited in 2026Q1. With aggregate exposure this small and zero activity this quarter, cohort interest in MX appears dormant rather than building.
