5 Tools for SEC Filings and Related Public Data

Public SEC filings are free to read. A third-party tool can make one research task easier, but the SEC's EDGAR search is the place to confirm what was filed.

This list groups five tools by the job they help with. It does not score their speed, mobile design, or paid features. Those can change, so check each provider before you choose a workflow.

SEC EDGAR: the original record

The SEC offers company search, full-text search, and a Latest Filings view that it describes as real time. You can search for a company or person, filter filings, and read the document and its exhibits. The SEC's data APIs also provide submissions history by company.

Use EDGAR when you need to verify a filing, read its full text, or check whether an amendment changed an earlier report. A summary elsewhere can point you to a filing; the filing gives you the company's actual disclosure.

Earnings Feed: follow filings across companies

Earnings Feed has a filings feed, form hubs, and company pages. Use them to find recent filings and move between companies and forms. If you follow a set of companies, a watchlist can keep that group together.

I built Earnings Feed, so this is a first-party description. For a consequential claim, open the linked SEC document and read it yourself.

OpenInsider: screen reported insider transactions

OpenInsider's screener lets you filter Form 4 transactions by ticker, insider, filing date, trade date, and transaction code. It also shows cluster buys.

A reported purchase is not the same as a verified signal. The SEC defines Form 4 code P as an open-market or private purchase. Check the original Form 4 and its footnotes before you interpret the trade.

Last10K: read company reports

Last10K's help page describes a company search that presents 10-K, 10-Q, and 8-K filings. That can be useful when you want to stay with one company and move between its reports.

The provider has both free and premium features. Check access to a specific export or screen before you plan a workflow around it.

Quiver Quantitative: add other public records

Quiver Quantitative lists datasets for congressional trading, government contracts, lobbying, and insider trading. Its visitor plan lists free features, while other tools need a paid plan.

This is a companion to SEC research, not a substitute for EDGAR. For congressional trades in particular, compare the transaction date with the disclosure date before you use the data as a timeline.

A simple workflow

Start with the question. For a new company filing, use EDGAR or a filing feed and read the original document. For an insider trade, use a screener to find it and Form 4 to understand it. For another public dataset, inspect the provider's source and dates.

You can begin with the Earnings Feed filings feed and keep SEC EDGAR open for verification. The source document matters more than which tool helped you find it.
