McGarry Kimberly J (Chief Accounting Officer) sold 8,692 shares of Zoom Communications, Inc. on Oct 13, 2026, a filing that scored 89 (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 (Subotovsky Santiago, McGarry Kimberly J, Chang Michelle, Sankarlingam Velchamy) traded ZM the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
