What this data is

Insider transactions

When a company insider trades the company's stock, they have two business days to file a Form 4 with the SEC. This page lists those filings as they arrive, with each transaction's filer, what they did, how many shares, at what price, and how many they hold afterward.

Most Form 4 activity is routine: option exercises, tax withholding, scheduled sales under a 10b5-1 plan. What matters is the open-market purchase, an insider spending their own cash at the market price. Those are flagged separately so you can filter to them.

Filings are grouped by ticker; each company page shows the full history for that company, so a purchase can be read against what the same insider did last year and what their colleagues are doing now.

Two other filings sit next to the Form 4s here. A Form 144 is the notice an insider or large holder files before selling restricted or control stock through a broker, so it shows planned sales before they happen, with the share count and market value. Schedule 13D and 13G are the cover pages filed by anyone who crosses 5% of a company's shares, 13D when they intend to influence the company and 13G when they are passive; both list the holder, the stake and the percentage of the class.

How to read it

  • Several insiders buying at once says more than one. One buyer can be personal; a group is a view.
  • Size relative to the insider's existing holding matters more than the dollar amount.
  • Selling is weak evidence on its own. Insiders sell for many reasons and buy for one.

Analysis of what the data shows, not advice. XOOMAR does not recommend buying, selling or holding anything.

Frequently Asked Questions

What is a Form 4?
SEC Form 4 is filed by corporate insiders (officers, directors, 10%+ owners) within 2 business days of buying or selling company stock.
Why focus on open-market transactions?
Open-market buys and sells are trades insiders chose to make. Option exercises, awards and gifts aren't counted in the headline tables.
What does insider buying mean?
An insider buying on the open market is spending their own money at the market price. One purchase says little; several insiders buying at once is the pattern most readers look for. It isn't a recommendation.
What counts as cluster buying?
Several different insiders buying the same company's stock on the open market within a few weeks. The table lists the buyers, their titles, the combined value and the dates; the API returns the same list, and an account rule can email you when a cluster forms.
How often does this update?
Every 30 minutes. The SEC publishes filings throughout the trading day.
Is there per-ticker data?
Yes. Click any ticker to open its company page, which stacks the Form 4 history with the planned sales, 13D and 13G filings, short interest and short volume for the same company. Every series is also on the API.
What is a Form 144?
The notice an affiliate or holder of restricted stock files with the SEC on or before placing a sell order with a broker, when the sale exceeds 5,000 shares or $50,000 in three months. It states the shares, their market value, the shares outstanding and the approximate date. The sale itself shows up later on a Form 4 if the seller is an insider.
What is the difference between 13D and 13G?
Both are filed by anyone who owns more than 5% of a class of a company's shares. 13D is for holders who may seek to influence or control the company and must be filed within five business days; 13G is the short form for passive and institutional holders. Amendments report changes of more than 1% or a change in intent.
