Is the Space and Nuclear Energy “Dual Engine Drive” Just the Beginning of This Interstellar Gold Rush?

RKLB is the first stock I've held for over a year. The space concept rally keeps gaining momentum. Yesterday, Trump signed an executive order to ensure America leads the world in space exploration, security, and commercial ventures, further boosting space and nuclear energy development. Now the stock price has hit $70 for the second time. Is it time to sell everything? Or should I hold on? Will this interstellar gold rush continue?
