EDGAR — the SEC's filing database — is one of the most powerful tools available to retail investors. Every material event at every public company is disclosed there within days. The problem isn't access; it's knowing what to look for.
This guide cuts through the jargon. We'll show you the 5 filing types that matter most, what to look for in each, and how to find the red flags that most investors miss entirely.
EDGAR (Electronic Data Gathering, Analysis, and Retrieval) is at sec.gov/edgar. To look up filings for a specific company:
https://www.sec.gov/cgi-bin/browse-edgarhttps://www.sec.gov/cgi-bin/browse-edgar?action=getcurrentEDGAR's full-text search lets you search for specific phrases across all filings. Try searching "at-the-market" or "variable rate conversion" to find companies with active dilution programs.
Must be filed within 4 business days of a material event. This is how companies announce earnings misses, executive departures, financing agreements, and offering announcements.
"...entered into a Securities Purchase Agreement with [investor name] for the issuance of a Senior Convertible Note in the principal amount of $X,XXX,000... convertible at 70% of the lowest VWAP during the 10 trading days prior to conversion..."
Translation: toxic financing. Run.
Registers securities for future sale. Companies can file this and then execute the actual offering weeks or months later. Filing an S-3 does not mean shares are being issued yet — but it means they can be.
This is it. When a 424B is filed, shares are being sold. The offering price, number of shares, and terms are in this document. By the time most investors see the news, the stock has already repriced.
424B3 — Most common. Used for ATM programs and ongoing shelf takedowns. See multiple 424B3s? Active ATM program.424B4 — IPO or large registered offering. The "big event" offering.424B5 — Prospectus supplement to an existing S-3 shelf. The offering is happening now.The most comprehensive financial disclosure. 10-K is annual, 10-Q is quarterly. Most investors skip to the headline numbers. The real information is buried in the footnotes.
The proxy is filed before annual shareholder meetings. Most investors ignore it. That's a mistake.
Retail investors rarely vote their shares, so management almost always gets what they want in the proxy. An authorized share increase proposal is essentially a dilution green light. If you see one filed, assume it passes.
Certain phrases appear across filing types. Train yourself to search for these when reviewing any SEC document:
"Going concern" — Auditors doubt the company can continue operating"Variable rate conversion" or "floating conversion price" — Toxic financing"Additional capital to fund operations" — They're running out of money"At-the-market offering" or "equity distribution agreement" — ATM program active"Beneficial ownership limitation" — Often seen in toxic notes to hide the full dilution"Authorized but unissued shares" followed by a large number — Dilution reservoir"Substantially all of our revenues" from one customer — Concentration riskHere's the honest truth: manually checking EDGAR for every stock you follow is unsustainable. A 20-stock portfolio generates hundreds of filings per month. You will miss things.
