The strongest recent filing
Tobin Jack J (MD Chief Accounting Officer) bought 700 shares of CME GROUP INC. on Sep 15, 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: 11 insiders (McCourt Timothy Francis, Marchese John Clifford, Dennis Michael G., Cutinho Sunil) traded CME the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with CME GROUP INC.'s own history
Open-market buys make up 42% of the 124 scoreable CME transactions on record between Nov 20, 2025 and Oct 22, 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.
