SEC EDGAR filing search

SEC EDGAR, short for Electronic Data Gathering, Analysis, and Retrieval, is the Securities and Exchange Commission's public database of company filings. It's where every Form 4 insider trade, every 13F institutional holdings report, and every 10-K annual report becomes available to the public, typically within minutes of being filed. Anyone can search it for free, and it's the primary source behind most insider and institutional trading data available anywhere.

What it measures

EDGAR is the SEC's central repository for filings that public companies, insiders, and institutional investors are legally required to submit. Electronic filing was phased in through the 1990s and became mandatory for most filers by 1996, replacing paper submissions. It holds the full range of required disclosures: registration statements, quarterly and annual reports, proxy statements, ownership filings like Forms 3, 4, and 5, and 13F institutional holdings reports, indexed by company and searchable by ticker, name, or filer.

How to read it

The practical value of EDGAR for a trader is less about browsing it directly and more about knowing it's the underlying source when a data provider reports an insider trade or a fund's new position. A filing's presence on EDGAR, and its timestamp, is the authoritative record. If a headline claims an executive bought or sold shares on a specific date, the underlying Form 4 on EDGAR is what confirms the transaction code, share count, and price, since secondary reporting occasionally summarizes filings imprecisely.

What it does not tell you

EDGAR shows what was filed, not whether it was filed correctly or completely. It has no independent power to verify a filer's disclosures beyond basic form requirements, and errors or late amendments do happen. It's also not real-time in the sense of showing trades as they happen, only the filings that report them after the fact, subject to whatever deadline applies to that filing type: two business days for Form 4, 45 days for 13F. Full-text search only covers filings back to 2001, so pulling older historical filings requires browsing by company rather than keyword. And EDGAR itself applies no judgment to what it hosts. A late amendment correcting an earlier Form 4's share count sits right alongside the original, and a reader has to notice the amendment exists rather than relying on EDGAR to flag it.

Worked example

A trader sees a headline claiming a semiconductor company's CFO bought $2 million in stock. Pulling the actual Form 4 from EDGAR confirms the transaction code, P for open market, the exact share count and average price, the filing date, and whether a 10b5-1 plan was checked, details a summary article might round off or omit. That same EDGAR search also surfaces the company's most recent 13F filers if the trader wants to cross-check whether institutional buying lines up with the insider purchase, since both filing types live in the same public system.
