How we classify it
Wealth adviser, per its Form ADV of Apr 8, 2026 (medium confidence).
The data, as reported: OVERBROOK MANAGEMENT CORPORATION (CRD 117884): 5.D assets by client type: high net worth 52%, charities 26%, pooled vehicles 17% (of $1.1 bn); 5.F 311 accounts, 32% non-discretionary; 5.D 123 clients, 105 individuals; signals: 5.G(1) financial planning, 5.G(7) selection of other advisers, 32% of assets non-discretionary
The type comes from a rule applied to that data. If it looks wrong, tell us.
Not counted as a concentrated manager: it is a wealth adviser; its 13F adds up client accounts. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
Managers of a similar size
A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
