Reading

The most ordinary reading of several insiders buying in the same window is directors and officers adding to holdings in an open trading window, often after results are public. 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.
