Why super-investors own VST
Stephen Mandel anchors the cohort's $1.4B collective position, with VST representing 7.4% of his portfolio — the highest concentration among the four holders and a $930M commitment that alone accounts for the majority of cohort exposure. David Tepper added to his position this quarter, bringing his stake to $304M (5.1% of his portfolio), the only move in an otherwise static quarter. Harry Burn and Joel Greenblatt round out the four owners, though Greenblatt's 0.1% weighting signals a negligible allocation. Cohort ownership has oscillated between two and four holders over the past eight quarters, suggesting this is a high-conviction stock for a small subset rather than a broad consensus name — interest is neither building nor fading meaningfully.
