Spot the edge. Swoop in.

Every insider purchase or sale you've ever read about in a news article or screener started as a raw Form 4 on SEC EDGAR. This guide walks through finding a company's filings on EDGAR and reading every field on the form itself, so you can go straight to the primary source instead of relying on a third-party summary.

Direct Answer

To read a Form 4 on SEC EDGAR, search for the company at sec.gov/cgi-bin/browse-edgar?action=getcompany, filter its filings to type "4," and open the specific filing. Table I reports common stock transactions (purchases and sales), Table II reports derivative securities like options, and the header shows the reporting owner's identity and role, the transaction date, the filing date, the price per share, and the insider's total ownership immediately after the transaction.

Key Takeaways

How Do You Find a Company's Form 4 Filings on EDGAR?

SEC EDGAR (Electronic Data Gathering, Analysis, and Retrieval) is the SEC's public filing database, and every Form 4 filed by a company insider is available there for free, typically within hours of submission.

Step 1: Search for the company

Go to EDGAR's company search tool at sec.gov/cgi-bin/browse-edgar?action=getcompany and enter the company's name or ticker symbol. This returns the company's EDGAR filer page, listing every type of filing it has submitted, from annual reports (10-K) to ownership filings (Forms 3, 4, and 5).

Step 2: Filter to Form 4

On the company's filing page, use the filing-type filter and enter "4" to narrow the list to Form 4 filings only, sorted with the most recent filing first. Each row shows the filer (the reporting insider, not the company), the filing date, and a link to the filing itself.

Step 3: Alternative — EDGAR full-text search

For a broader search across companies, or to search filing text directly, EDGAR's full-text search interface at sec.gov/edgar/search lets you filter by form type, date range, and other criteria without starting from a specific company's filer page. This is useful when you're researching a specific insider's name across multiple companies rather than one company's full insider roster.

Common Mistake

The common mistake is searching for the insider's name instead of the company's name or ticker when first landing on EDGAR. The company search tool is built around company identifiers; searching an individual's name works better through the full-text search interface or a third-party insider-tracking aggregator built specifically for that use case.

What Does Each Section of a Form 4 Show?

Once you open a specific Form 4, the form follows a consistent structure regardless of which company filed it. Here's what each section reports.

Reporting-owner section

Near the top of the form, the reporting-owner section identifies the insider by name and lists checkboxes for their relationship to the company: director, officer (with a title field, such as "Chief Financial Officer"), 10% owner, or "other." This section explains why the filer is required to report at all — Section 16 of the Securities Exchange Act only applies to officers, directors, and holders of more than 10% of any class of the company's equity securities.

Table I — Non-Derivative Securities

Table I reports transactions in non-derivative securities, which in practice almost always means common stock. Each row includes:

Table II — Derivative Securities

Table II reports derivative securities: stock options, restricted stock units, stock appreciation rights, and similar instruments whose value is tied to the underlying stock rather than being the stock itself. In addition to the fields shared with Table I, Table II includes the security's exercise or conversion price and expiration date, since these are relevant details for an option or RSU that don't apply to a straightforward share.

A common Table II entry is an option exercise (transaction code M), which is frequently followed by a same-day sale of the resulting shares reported separately in Table I. Reading both tables together for the same filing date shows whether an insider is exercising and holding the underlying shares, or exercising purely to sell.

Transaction date vs. filing date

The transaction date (found within Tables I and II) is when the trade actually occurred. The filing date, shown near the top of the form, is when the insider submitted the Form 4 to the SEC. Section 16 requires filing within two business days of the transaction date, so the gap between the two dates is normally small. A materially wider gap can indicate a late filing, which the SEC and some third-party trackers flag separately.

Post-transaction ownership column

Both tables include a column reporting the insider's total beneficial ownership immediately after the transaction, not the size of the transaction itself. This figure is what lets you calculate how meaningful a purchase or sale is relative to the insider's existing position — an 8,000-share purchase means something very different for an insider who owned 5,000 shares beforehand than for one who owned 5 million.

Common Mistake

The common mistake is reading only the transaction amount in isolation and skipping the post-transaction ownership column. The same 5,000-share purchase can represent a first-ever, high-conviction stake for one insider and a rounding-error addition to an existing multi-million-share position for another; the post-transaction ownership figure is what distinguishes the two.

Worked Walkthrough: Reading a Filing Start to Finish

  1. Search EDGAR for the company. Enter the ticker at sec.gov/cgi-bin/browse-edgar?action=getcompany and land on the company's filer page.
  2. Filter to Form 4 and open the most recent filing. The list shows the reporting owner's name and the filing date; open the top row.
  3. Check the reporting-owner header. Suppose the box checked is "Officer," with the title field reading "Chief Financial Officer." This is a Section 16 officer, not a rank-and-file employee, and their trades carry Form 4 reporting obligations for that reason.
  4. Read Table I. One row shows a transaction date of March 4, code P, an amount of 4,200 shares (acquired), a price of $18.65, and shares owned following the transaction of 26,800. This is a straightforward open-market purchase.
  5. Check Table II. If Table II is empty or shows no new rows on the same filing, this filing reports only the stock purchase, not an accompanying option exercise.
  6. Compare filing date to transaction date. If the filing date at the top reads March 5, one business day after the transaction, this filing is within the required two-business-day window.
  7. Interpret the position size. A 4,200-share purchase against a resulting 26,800-share position is roughly a 19% increase in the CFO's holdings — a meaningful, not token, addition.

Misconceptions Versus Reality

MisconceptionReality
All Form 4 transactions represent the insider spending their own money to buy stockMost Table I and Table II entries are grants, awards, option exercises, or gifts — only code-P open-market purchases represent a discretionary cash purchase
The "amount" column shows the insider's total stakeThe amount column shows only the size of that specific transaction; the separate "shares owned following the transaction" column shows the total position
A Form 4 always reports a single transactionA single Form 4 can report multiple transactions across Table I and Table II if they occurred on the same or nearby dates and are filed together
The filing date tells you when the trade happenedThe filing date is when the form was submitted to the SEC; the separate transaction date field is when the trade actually occurred, generally up to two business days earlier
A blank price column means the data is missing or the filing is incompleteA blank price column is normal for non-market transactions like grants and gifts, where no cash price was paid

Frequently Asked Questions

Where do I find a company's Form 4 filings on EDGAR?

Go to the SEC's company search tool at sec.gov/cgi-bin/browse-edgar?action=getcompany, enter the company's name or ticker symbol, and open its EDGAR filing page. From there, filter the filing type to "4" to see only Form 4 ownership filings, listed with the most recent first.

What is the difference between Table I and Table II on a Form 4?

Table I reports non-derivative securities, primarily common stock transactions such as open-market purchases and sales. Table II reports derivative securities, including stock options, restricted stock units, and other instruments whose value derives from the underlying stock, along with details like exercise price and expiration date that don't apply to a straightforward share purchase.

What is the difference between the transaction date and the filing date on a Form 4?

The transaction date is when the insider actually bought or sold the security. The filing date is when the Form 4 was submitted to the SEC, which must occur within two business days of the transaction date under Section 16 rules. A wider-than-normal gap between the two dates can indicate a late filing, which is itself sometimes worth noting.

What does the post-transaction ownership column show?

The post-transaction ownership column in Table I (and Table II, for derivative holdings) reports the total number of shares or derivative units the reporting owner beneficially owned immediately after the reported transaction, not just the size of that single transaction. Comparing this figure to the transaction size shows what fraction of the insider's total position the purchase or sale represents.

What does the price column on a Form 4 mean if it's blank?

A blank or zero price column typically indicates the transaction wasn't a market purchase or sale at a negotiated price, such as a stock grant, award, or gift, where no cash price changed hands. Open-market purchases and sales (transaction codes P and S) almost always show a specific price per share.
