If you add up GE Aerospace, RTX Corporation, The Boeing Company, Lockheed Martin, Northrop Grumman, and General Dynamics put together you get a market cap of about 1T btw.
Those companies aren't considered "tech" so their share prices observe the laws of gravity. A single tweet about xAI-powered nuclear drones launched from the moon or whatever would probably cause the stock to go up 50%. And pumping the stock is all that matters.
