Rubico is trading 12% down at $0.44 in after-hours, with the catalyst unclear. - It closed the regular session at $0.50 on October 9, 2026, after falling over prior sessions; the broad market rose that day. - No October 9 company-specific announcement or verified report explaining the decline was found. - The 50% stock dividend went ex-dividend October 6, but that earlier event does not establish the cause of this after-hours decline.
