What Forms 3, 4 and 5 cover
Directors, certain officers and owners of more than 10% of a covered class of equity securities report their holdings and transactions under the SEC’s insider-reporting rules. Form 3 provides an initial ownership report. Form 4 reports changes, and Form 5 covers certain transactions not reported earlier.
Look at the transaction code
A purchase, a sale, a stock award and a gift are different events. The transaction code and footnotes help explain the change. Do not assume that every increase in shares reflects a purchase using the person’s own cash.
Read the details around the number
Check the transaction date, security type, price, number of shares and whether the ownership is direct or indirect. Footnotes may describe conditions, entities through which shares are held, or other context that a summary leaves out. Compare the transaction date with the filing date.
Treat it as a research input
An insider transaction does not by itself establish a company’s outlook or the reason for the trade. Keep the original filing beside your notes and compare it with the company’s financial reports and announcements. Avoid turning an ownership change into a guaranteed signal.
