Rubico is trading 19.96% up at $0.84 in pre-market on October 6, 2026; no fresh company announcement explaining the move was found.
- The reported prior close is $1.05. The supplied figures appear inconsistent, so the stated percentage is reported without recalculation.
- Rubico expected its shares to begin trading on a stock-dividend-adjusted basis around October 6, following a previously announced 0.50-share dividend for each share.
- The SEC filing does not say the adjustment caused the pre-market move.
