The strongest recent filing
South Thomas A (President) sold 8,606 shares of NORTHERN TRUST CORP on Feb 17, 2026, a filing that scored 91 (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: 9 insiders (Cherecwich Peter, Taylor Alexandria, O'Grady Michael, Tyler Jason J.) traded NTRS the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with NORTHERN TRUST CORP's own history
Open-market buys make up 54% of the 114 scoreable NTRS transactions on record between Oct 27, 2025 and Oct 17, 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.
