What EDGAR is
EDGAR does two jobs. It is the filing system: companies and others submit documents to the SEC through it under the federal securities laws. And it is the public archive: the SEC describes it as holding millions of documents filed by publicly traded companies and others, open to anyone at no cost.
The filers are a wide group:
- Operating companies filing annual and quarterly reports, current reports, proxies and registration statements.
- Insiders, meaning officers, directors and holders of more than 10% of a class of stock, filing ownership forms such as Form 4.
- Large holders and activists filing beneficial ownership reports such as Schedule 13D and 13G.
- Funds, including mutual funds and ETFs, filing holdings and fund documents.
- Institutional managers filing quarterly 13F holdings reports.
Every data terminal, screener and newsletter that reports on US public companies draws on these documents. EDGAR is the source; the rest are copies, summaries or reformatted versions.
How a filing is built
Every EDGAR filing has the same parts. Learning them once makes any filing quick to read.
| Part | What it is | Why it matters |
|---|---|---|
| CIK | The filer's permanent Central Index Key | Survives name and ticker changes |
| Accession number | A unique ID for one submission | Lets you cite and recheck a source |
| Form type | The rule the filing is made under, such as 10-Q or 8-K | Tells you what to expect inside |
| Filing date and period | When it was filed and the period it covers | Places the facts in time |
| Main document | The form itself | The required disclosures |
| Exhibits | Attached agreements, releases and letters | Often hold the terms that decide a situation |
| XBRL data | Tagged financial figures | Lets software read the numbers |
The CIK identifies the filer. The SEC assigns one to every electronic and paper filer, foreign and domestic. A company that renames itself after a merger keeps its CIK, so the number is the reliable way to pull its full record.
The accession number identifies one submission. Each filing has its own index page listing every document in it. Record the accession number for any figure you use, and you can return to the exact source in seconds.
Exhibits carry much of the substance. In a deal announcement, the press release is often Exhibit 99.1 and the merger agreement is often Exhibit 2.1. The release is the summary; the agreement holds the outside date, the termination fee and the closing conditions.
When filings become public
Timing is where EDGAR matters most for anyone following a dated event. Per the SEC, EDGAR accepts filings on business days from 6:00 a.m. to 10:00 p.m. ET. A submission started after 5:30 p.m. ET is generally disseminated the next business day; ownership forms 3, 4 and 5 have a 10:00 p.m. ET cutoff instead.
Two filing deadlines set the pace of most news:
- Form 8-K: unless otherwise specified, it must be filed or furnished within four business days of the event it reports.
- Form 4: an insider must file within two business days following the transaction date. Our guide to tracking insider buying with Form 4 covers how to read one.
Periodic reports follow their own calendars. A 10-Q is due 40 or 45 days after quarter end depending on filer status; see how a 10-Q differs from a 10-K.
Once disseminated, a filing reaches the public quickly. The SEC states that its submissions API updates in real time, with a typical delay of about a second, and its XBRL APIs within about a minute, longer at peak filing periods.
Four ways to search EDGAR
Each search tool fits a different question. Pick by what you know and what you want.
Company search: one filer's full history
Type a name, ticker or CIK and you get the filer's list of filings, newest first, filterable by form type. Use it when you know the company and want a specific report, or want to see what it has filed recently. A cluster of 8-Ks or a new proxy says something is happening before you read a word.
Full-text search: a phrase across all filers
EDGAR full-text search reads inside the documents, covering filings since 2001. You can filter by date, company, person, filing category and location. Use it when you know the words but not the company, for example "plan of liquidation" in proxies or "substantial doubt" in quarterly reports. Put phrases in double quotes to match them exactly.
Latest Filings and RSS: what is arriving now
The Latest Filings page shows submissions in real time as EDGAR accepts them, and can be narrowed by form type. Each company page also offers an RSS feed. These are the free way to follow a watchlist. The SEC does not send email alerts for company filings, so email alerts mean a third-party service; our comparison of SEC filing tools and EDGAR alerts covers the options.
APIs: filings as data
The data.sec.gov APIs return a filer's submission history and its XBRL financial data as JSON. They need no API key. The fair access policy currently caps automated requests at 10 per second and asks each request to declare a user agent naming the requester and a contact email. Scripts that ignore this can be blocked.
- If you know the company and want a document, use company search.
- If you know a phrase but not the company, use full-text search.
- If you want to see filings as they arrive, use Latest Filings or RSS.
- If you want numbers for many companies at once, use the APIs, then check key figures against the filings.
What EDGAR does not contain
EDGAR is broad but not complete, and knowing the gaps saves time.
- Older paper filings. The public filing indexes begin in the third quarter of 1994. Earlier paper documents are not on EDGAR and must be requested from the SEC.
- Full-text search before 2001. Filings from the 1990s can be found through company search or the index files, but not by phrase.
- Market data. EDGAR holds filings, not prices, volume, short interest or options data.
- Verification. A filing is the filer's own statement, made under legal liability. Its appearance on EDGAR does not mean the SEC has checked or approved it.
- Earnings call commentary. Calls are not filings, though many companies furnish the earnings release on an 8-K.
How event-driven investors use EDGAR
In special situations, the thesis usually depends on a document rather than a data point. A few form types do most of the work:
- A Form 10 registers a spin-off and describes the new company's business and capital structure. See what a Form 10 is.
- A Schedule 13D shows an active holder above 5% and its stated intentions. See what a 13D filing is.
- A DEF 14A or DEFM14A sets the meeting date and the terms of a vote. See what to read in a proxy statement.
- A Schedule TO sets out a tender offer's price, expiration and conditions.
Dombey's published research cites the EDGAR filing behind each figure; see the research archive.
Where this goes wrong
Reading the release and skipping the exhibit. The company writes the press release. The agreement and the notes hold the terms that move a deal or a liquidation.
Missing amendments. A 10-K/A, an amended Schedule TO or a supplemental proxy can replace the facts you relied on.
Picking the wrong filer. Parents, subsidiaries, trusts and predecessors have separate CIKs. Check the address and state of incorporation.
Trusting tagged data over the document. XBRL figures are convenient but can carry tagging errors. Check any number that matters against the filing itself.
Misreading the date. A filing submitted late in the evening can show the next business day. When timing matters, check when it was accepted, not only the date on the list.
The bottom line
EDGAR is the SEC's filing system and the free public record of what companies, insiders and funds file. Every filing has a CIK, an accession number, an index page, a main document and usually exhibits, and the exhibits often carry the terms that matter. Use company search for one filer, full-text search for a phrase, Latest Filings or RSS for new submissions and the APIs for data at scale. Read the document behind every figure, check for amendments and record where each number came from.
