The strongest recent filing
Dickson Zoe L (EVP & Chief HR Officer) sold 25,055 shares of 3M CO on Feb 9, 2026, a filing that scored 95 (Strong). It scored Strong because a senior insider was trading and several insiders moved the same way within a week. The score describes the filing, not future returns. This is not investment advice.
Cluster activity
A cluster buy is present: 7 insiders (Reinseth Theresa E, Dickson Zoe L, Chavez Rodriguez Beatriz Karina, Rhodes Kevin H) traded MMM the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with 3M CO's own history
Open-market buys make up 12% of the 108 scoreable MMM transactions on record between Oct 24, 2025 and Oct 7, 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.
