Sourced from this company's own SEC submissions record. The industry label is SEC's Standard Industrial Classification, which is more specific than the Industrials sector shown above.

Open-market purchase (code P)

An insider spending their own money at market price. This is the only buy code that reliably carries signal — it is a decision, not compensation.

Grants and option exercises (codes A, M)

Scheduled compensation. Most "insider buying" headlines are really this, which is why InsiderPulse weights it at a fraction of a real purchase.

Cluster buy

Two or more different insiders buying on the open market in the same window. One executive buying can mean anything; three is much harder to explain away.

Where does FAST insider trading data come from?

From the Form 4 filings Fastenal Company's officers, directors and 10% owners must send the SEC within two business days of a trade. Each row on this page links to its original filing on SEC EDGAR. Share grants and option exercises are kept apart from open-market purchases and sales, because only the latter cost the insider their own money.
