The GuruFocus All Gurus Dataset offers comprehensive, structured access to the public filings and trades of over 17,000+ institutional investors, including hedge funds, value investors, pension funds, and asset managers. Ideal for data platforms, quant researchers, and investment product developers, this dataset brings transparency to professional fund activity.
Updated quarterly and compliant with SEC 13F, 13D, and 13G disclosures, this dataset enables the construction of guru-following strategies, trend analysis, and institutional benchmarking — all normalized for easy analysis and integration.
