Investor Rankings

Leaderboards built from the most recent SEC 13F filings

For educational research only.InvestorLens analyzes public regulatory filings (SEC EDGAR, STOCK Act PTRs) that may be delayed by 45 days or more. Information shown is historical and is not financial, legal, or tax advice, nor a recommendation or solicitation to buy or sell any security. Always do your own research.

Each ranking sorts tracked institutional investors by a single metric derived from their most recent Form 13F-HR filing — concentration, sector exposure, portfolio turnover, and more. All data is sourced from SEC EDGAR and is descriptive only, not investment advice.
