The cluster is entirely active asset managers with no passive/index fund participation, suggesting a deliberate thesis. However, the 45-day reporting lag means positions may have changed since quarter-end. Watch for any Q4 13F filings or insider Form 4 activity to confirm continued conviction.
Executive Summary
Three asset managers (Ninety One UK, Truist Financial, Asset Management One) increased their MWH positions in Q3 2026, with Ninety One UK nearly quadrupling its stake to $36.8M. One small seller exited nearly entirely, resulting in a net institutional inflow of approximately $27M. The cluster is active-manager-driven but lacks insider buying corroboration.
