The strongest recent filing
KRISHNA ARVIND (President) sold 41,133 shares of INTERNATIONAL BUSINESS MACHINES CORP on Feb 1, 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 (KRISHNA ARVIND, LAMOREAUX NICKLE JACLYN, Robinson Anne, Fehring Nicolas A.) traded IBM the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with INTERNATIONAL BUSINESS MACHINES CORP's own history
Open-market buys make up 60% of the 88 scoreable IBM transactions on record between Dec 31, 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.
