From SEC's quarterly Form 3, 4 and 5 data sets: code P purchases and code S sales of common stock, by the date the trade happened. Where a fund and the people who control it each report the same block, it is counted once. Trades made in the last days of Q2 2026 but filed after it closed arrive with SEC's next quarterly release.

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 ON insider trading data come from?

From the Form 4 filings ON Semiconductor Corporation'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.
