Star Bulk Carriers is trading 9.5% up in after-hours at $29.89; the reason remains unclear. - This compares with the November 3 regular-session close of $27.30. - No verified November 3 company announcement or news report explains the move. Listings place the next earnings announcement in mid-November, not November 3, so earnings do not appear to explain it. - Available reporting does not establish a sector or broad-market catalyst; earlier dry-bulk freight weakness accompanied a decline, not this after-hours rise.
