Why super-investors own PTEN
Ownership of PTEN within this cohort is thin and largely static: three managers hold a combined $26M, with Kahn Brothers Group accounting for the bulk at $18M and a 3.2% portfolio weight — the only holder with meaningful conviction. Joel Greenblatt carries roughly $7M but at a negligible portfolio weight, and Lee Ainslie's position is under $800K. No one added, trimmed, started, or exited in 2026Q1, suggesting quiet holding rather than active thesis-building. The eight-quarter owner count tells a clear story: the cohort peaked at two holders and has flatlined at one for most of that stretch before the recent marginal uptick to three. Interest is neither rising nor fading — it is essentially dormant.
