The strongest recent filing
HENNESSY SEAN P (Director) bought 46 shares of TransDigm Group INC on Sep 18, 2026, a filing that scored 82 (Strong). It scored Strong because several insiders moved the same way within a week and it was direct personal ownership. The score describes the filing, not future returns. This is not investment advice.
Cluster activity
A cluster buy is present: 10 insiders (HENNESSY SEAN P, Graff Michael, BARR DAVID, SMALL ROBERT J) traded TDG the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with TransDigm Group INC's own history
Open-market buys make up 4% of the 521 scoreable TDG transactions on record between Nov 20, 2025 and Oct 15, 2026. Comparing a filing with the company's own buy/sell mix is how you tell a routine disposal from an unusual accumulation.
Methodology and sources
Scores come from six published, user-adjustable factors (insider role, cluster activity, trade size versus the insider's own history, position impact, filing urgency, and direct versus indirect ownership). The score describes the filing, not future returns. This is not investment advice.
