Why super-investors own WM
Ownership of WM within this cohort is almost entirely a single-name story: the Bill & Melinda Gates Foundation Trust holds $6.4B of the cohort's $6.6B combined position, making WM 20.1% of that portfolio — a concentration level that signals foundational, long-term conviction rather than a tactical trade. Four smaller managers — Jensen, Mairs & Power, Terry Smith, and Greenblatt — fill out the five-owner count, but their combined exposure is modest. Activity this quarter was flat across the board, with no additions, trims, or exits recorded. The cohort count has been stable at two core holders for six consecutive quarters before the recent expansion to five, suggesting gradual, quiet accumulation rather than a momentum-driven surge. Overall interest is steady rather than building.
