The EDGAR system
What is SEC EDGAR?
Updated
EDGAR, the Electronic Data Gathering, Analysis, and Retrieval system, is the SEC’s public database of company filings. Every 10-K, 10-Q, 8-K, proxy, prospectus, and insider Form 4 filed by a U.S. public company lands there, and anyone can read it for free, usually within seconds of filing. It is the primary source behind most financial data products, Scrutar included.
How EDGAR is organized
Two identifiers do the structural work. Every filer, whether a company, a fund, or an individual insider, has a CIK, a permanent Central Index Key that survives ticker changes and renames. Every filing has an accession number, a unique ID encoding who submitted it and the year. A filing is really a folder of documents: the primary document, exhibits (contracts, press releases), and data files, all listed in a filing index.
Thanks to XBRL, financial statements are also machine-readable, and the SEC publishes company facts, filing histories and submissions in formats that software can read directly, free of charge.
When filings appear
Timing has quirks. EDGAR accepts filings until 10 p.m. Eastern, but a filing accepted after 5:30 p.m. is generally dated the next business day. A short list keeps the same-day date right up to 10 p.m., including Forms 3, 4 and 5, Schedules 13D and 13G, and Form 144. That split explains the wave of documents that “land” at market close and after hours.
Searching it well
EDGAR rewards precise queries: full-text search for exact phrases across filings, company pages filtered by form type, and Section 16 pages for each insider. Its weaknesses are presentation and synthesis: raw filings, no aggregation, no cross-company views. That layer is what tools build on top. Scrutar reads new filings from EDGAR as they are published and turns them into browsable pages:every covered company, per-company filing timelines like Apple’s, and cross-market feeds like the latest insider trades.
Why it matters
EDGAR embodies the disclosure bargain at the heart of U.S. securities law: companies may raise money from the public, and in exchange the public gets the documents. Most of what appears on financial charts and screens traces back to something filed on EDGAR, so it pays to learn to read the source.
