How to read an insider purchase filing
Start with the transaction code and security title. Code P identifies a reported purchase on an exchange or in a private transaction. It can involve a derivative security, so a purchase record should not automatically be described as an open-market purchase of common stock. Company listings can include several tickers; the filing identifies the actual security.
What should I compare before using a purchase record?
Check the quantity, price footnotes, currency, and reporting-owner relationships in the original SEC filing. A reference value is quantity × price, not a verified cash settlement. Amounts in a joint filing are not allocated to each named owner. Unknown currencies stay unspecified, and different securities or currencies should not be added into one total.
How complete and current is this list?
These are the records currently loaded from SEC Forms 4, 4/A, 5, and 5/A. Historical collection is incomplete, and these pages do not promise real-time or complete market coverage. The latest view shows at most 50 records per page; use earlier-record links where available. An empty period is not proof that no purchases took place. Sales and net buying/selling totals are not provided.
Read the Form 4 transaction code guide, review common filing questions, or read the SEC investor bulletin. A reported purchase is not a recommendation to invest.
