Form 4 code P reports a purchase of securities, typically an open-market purchase of common stock. Among Form 4 codes, P is usually the cleanest buying signal because the insider is acquiring shares rather than receiving compensation stock.
The strongest code P context combines a meaningful dollar value, a relevant insider role, direct ownership, and nearby purchases by other reporting owners. That is why many filing-only signal pages start from code P rows.
- Used for insider buying screens and cluster-buying rules.
- Check whether the transaction is direct or indirect ownership.
- Compare purchase size with the insider's past transactions.
- Still verify price, shares, and footnotes in the original SEC filing.
