The strongest recent filing
Nave Ophir (COO) sold 106,718 shares of Nebius Group N.V. on Oct 5, 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: 6 insiders (Boroditsky Marc, Nave Ophir, Shtan Danila, Korolenko Andrey) traded NBIS the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with Nebius Group N.V.'s own history
Open-market buys make up 5% of the 120 scoreable NBIS transactions on record between Mar 31, 2026 and Oct 21, 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.
