How we classify it

Investment firm, per its Form ADV of Aug 12, 2026 (medium confidence).

The data, as reported: MAIN MANAGEMENT, LLC (CRD 120361): 5.D assets by client type: high net worth 65%, corporations 13%, pooled vehicles 13%, charities 6% (of $1.9 bn); 5.F 337 accounts, 17% non-discretionary; 5.D 253 clients, 213 individuals; no financial planning, adviser selection or non-discretionary assets: discretionary accounts

The type comes from a rule applied to that data. If it looks wrong, tell us.

Not counted as a concentrated manager: more than 20% is ETFs. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Similar managers by type and size

Same type of filer and a 13F portfolio value between a third and three times this one. It is not a comparison of what they hold.
