Why Track 13F Filings?
Every quarter, institutional investment managers with at least $100 million in qualifying assets must file Form 13F with the SEC. These filings reveal their long US equity positions, giving the public a window into what the world's top investors are buying and selling.
Tracking 13F filings lets individual investors see how hedge funds, pension funds, and family offices allocate capital. While filings lag by up to 45 days, they remain the most comprehensive public source of institutional portfolio data. Sites like Track13F make this data searchable and actionable.
