How this report is made
This report is compiled automatically from SEC Form 4 filings received during the week shown. Companies are ranked by the total dollar value of insider purchases (transaction code P, open-market or private purchase). “Insiders” include officers, directors and owners of more than 10% of a company, which can be investment funds. Only common stock is counted: preferred shares, units and derivatives are left out, as are filings that fail our data checks. When a fund and the insider who controls it both report the same trade, it is counted once. Only U.S.-based companies are ranked, because insiders of foreign companies sometimes report prices in their local currency.
Every figure comes from the original filing, which is linked in each entry; the filing is the authoritative record. This is information, not investment advice. See the methodology, disclaimer and corrections policy.
