Why super-investors own SSD

Ownership of SSD within this cohort is effectively a single-manager story: Jeffrey Ubben holds $240M worth, representing 4.2% of his portfolio and roughly 92% of the cohort's combined $260M position. John Rogers and Joel Greenblatt round out the three owners but at negligible weights (0.2% and near-zero, respectively). The cohort count has held flat at one dominant owner for at least eight consecutive quarters, and 2026Q1 saw zero activity — no additions, no trims, no entries or exits — suggesting Ubben's position is a stable, high-conviction anchor rather than an actively managed trade. With no new buyers emerging and existing holders static, broader cohort interest shows no signs of either expanding or fading.
