SEC EDGAR
Public online archive of the US Securities and Exchange Commission for all mandatory filings by listed companies and investment managers.
EDGAR stands for "Electronic Data Gathering, Analysis, and Retrieval" and is the central electronic filing system of the U.S. Securities and Exchange Commission (SEC). Since 1993 essentially every mandatory filing — including 10-K, 10-Q, 8-K, S-1, 13F, 13D, 13G and Form 4 — must be submitted through EDGAR and is publicly accessible there free of charge.
Raw EDGAR data is delivered as XML, HTML and, in some cases, XBRL. For 13F filings the "InformationTable" is the machine-readable core. Whaleboard parses these tables automatically, maps CUSIPs to tickers and sectors, and surfaces the data through interactive charts and tables.
