Why super-investors own ASML
Ownership within the cohort has expanded steadily from a low of three holders to ten today, with ASML's largest backer, Stephen Mandel, anchoring a $865M position that represents 6.9% of his portfolio and drives the bulk of the cohort's $2.2B combined stake. The 2026Q1 quarter was net additive: Daniel Loeb and Wallace Weitz opened new positions, and Valley Forge Capital Management added to its existing 6.7% allocation. Countering that, David Tepper and Pat Dorsey trimmed, and Duan Yongping exited entirely. Triple Frond Partners and Pat Dorsey carry the highest portfolio concentrations at 16.3% and 14.8% respectively, signaling strong conviction among a subset even as the broader trend of rising owner counts suggests widening — if not yet deep — interest across the cohort.
