KOID is trading at $36.00, up 3.84% after hours, with no verified company-specific catalyst identified. - The move compares with the October 13 regular-session close of $34.67. Major U.S. indexes were broadly flat or mixed, so the available evidence does not establish a broader-market explanation. - KOID is a humanoid robotics and physical AI ETF. October 13 coverage included industry expansion plans and increased scrutiny of Chinese robotics firms, but no evidence directly ties either development to the gain.
