How to read insider trading data

Insider buying is one of the most-watched signals in equity research, and for a simple reason: insiders sell stock for many reasons — diversification, taxes, a new house — but they generally buy for only one. When the people who know a business best are putting their own money into its shares, it can suggest confidence in what lies ahead. Sales are noisier, but a sudden cluster of selling by multiple insiders can still be worth a closer look.

On InsiderSource, each row shows the company, the insider and their role, the transaction type, and the dollar value of the trade. The colored bar under each entry scales with the size of the transaction, so the largest, most meaningful trades stand out at a glance. Green marks an acquisition of shares; red marks a disposal. Tap any company to see its full insider history and a 90-day buy-versus-sell summary.

Frequently asked questions

What is a Form 4 and who has to file one?

A Form 4 is a disclosure filed with the U.S. Securities and Exchange Commission (SEC) whenever a company "insider" — an officer, director, or beneficial owner of more than 10% of a company's stock — buys or sells shares. Insiders must file within two business days of the transaction, which is why this data is among the most timely windows into corporate sentiment.

Is insider trading legal?

Yes — the trades shown here are legal insider transactions that are fully disclosed to the SEC as required by law. Illegal insider trading involves buying or selling based on material non-public information. The Form 4 filings on this site are the transparent, reported trades that the law requires insiders to make public.

How fresh is the data on InsiderSource?

We read directly from the SEC's EDGAR system, the official source for all filings. New Form 4s typically appear here within minutes of being accepted by EDGAR. Because insiders have a two-day filing deadline, a trade you see today may have occurred up to two business days earlier.

Does an insider buy mean I should buy the stock?

No. Insider activity is one data point among many and is not a recommendation. Insiders can be wrong, and a single trade rarely tells the whole story. InsiderSource is an information tool, not investment advice. Always do your own research and consider speaking with a licensed financial professional.

What does the colored bar under each trade mean?

It is a conviction bar that scales with the dollar value of the transaction relative to others in the current view. A longer bar means a larger trade. Green bars are share acquisitions (buys, grants, exercises); red bars are dispositions (sales).
