About Whale Analyzer

Last updated: May 16, 2026

Whale Analyzer is a public-data research website for following notable investors, funds, institutions, insiders, and public-market portfolios. The site organizes SEC 13F filings and other public disclosures into a readable, bilingual interface.

Our mission: make public portfolio disclosures easier to scan, compare, and understand without turning them into investment advice.

What We Track

SEC 13F holdings for investment managers and institutions when local holdings data is available.
SEC Form 4 and Form 3 insider disclosures, labeled separately from institutional 13F portfolios.
Congressional and other public disclosures where the source and reporting limitations can be verified.

Data Sources

Most portfolio holdings on Whale Analyzer are derived from SEC EDGAR 13F filings. Other profiles use SEC insider filings, congressional disclosures, or clearly identified public sources. Each profile is labeled with its disclosure type, reporting period, and current data status; stale or very small datasets are not promoted in the searchable static index.

Editorial Approach

We rank and organize investors using a mix of public prominence, available portfolio data, and editorial categories such as value, hedge fund, growth, institution, insider, and political disclosure. Rankings are for navigation only and are not recommendations.
