Methodology
Top firms are ranked by their current AUM values. Growth $ and % values compare current reported AUM, employee count, and account counts against the latest historical filing on or before the 1 year, 3 year, and 5 year lookback dates, plus the earliest available historical filing for total growth. Metrics may show a dash where historical filings are unavailable or not reliable enough for the lookback period. This is not investment advice.
