The strongest recent filing
Spyrou Symeon (co CFO) bought 15,000 shares of Star Bulk Carriers Corp. on Sep 15, 2026, a filing that scored 85 (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: 8 insiders (Pappas Alexandros, Reskos Nikolaos, Plakantonaki Charis, Zagari Raffaele) traded SBLK the same direction within a 7-day window. Shared conviction is a stronger structural signal than a lone trade.
How this compares with Star Bulk Carriers Corp.'s own history
Open-market buys make up 31% of the 29 scoreable SBLK transactions on record between Mar 31, 2026 and Oct 13, 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.
