Why super-investors own THC
Stephen Mandel dominates this story: his $426M position represents 3.4% of his portfolio and accounts for roughly 84% of the cohort's combined $507M exposure to THC. Mandel added to his position in 2026Q1, reinforcing what is already the only high-conviction bet in the group. Joel Greenblatt holds a token $79M slice at 0.1% of portfolio, while First Eagle and Bill Nygren carry negligible exposure. The cohort history is telling — ownership stood at zero for six consecutive quarters before Mandel initiated in 2025Q3, and the count has held at just one serious owner since. Interest is neither rising nor fading broadly; this is effectively a single-manager thesis with Mandel adding weight to a position he alone built.
