Reading
The most ordinary reading of an open-market purchase by an insider is a director or officer adding to holdings in an open trading window. Form 4 does not state a reason, and this page does not infer one.
Scope: SEC Form 4, Table I (non-derivative) only — Table II (options, RSUs) is not shown; on multi-owner filings the first reporting owner; Senate PTRs are covered, House is not. Every filing is reconciled daily against EDGAR's own index — see coverage.
