The strongest recent filing
Gulfo Adele M. (Director) bought 567 shares of Enpro Inc. on Feb 12, 2026, a filing that scored 94 (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: 15 insiders (Bianchi Amy, Bower Steven R., Joiner Larisa R., McLean Robert Savage) traded NPO the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with Enpro Inc.'s own history
Open-market buys make up 77% of the 87 scoreable NPO transactions on record between Dec 17, 2025 and Sep 30, 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.
