Top insider buys this month
The companies whose own insiders — executives, directors and holders of 10% or more — bought shares on the open market this month, spending their own money at market price. Grants, option exercises and every other form of compensation are excluded, because they are not decisions. Ranked by how many different insiders bought, then by how much.

Only filings received since Aug 14, 2026 are retained, so trades before then appear here only if they were filed late. Treat this as Aug 14, 2026 – Sep 04, 2026 rather than the full 30 days.
The most-bought companies, by their own insiders
Clusters first — several people at one company independently choosing to buy is the hardest thing on the tape to explain away — then by dollars. Every row links to the company's own filing history.
