description: "The defense sector concept is getting active again, KTOS took off directly, up 6% in a day. Although Raytheon and Amphenol dipped slightly, the overall sentiment is still there. Every time the defense sector moves, it's driven by news. It's hard to say how long this kind of stock will last, but those who held and didn't sell today must be feeling pretty good. I'm the type who wants to sell on a spike but is afraid of missing out. I never feel secure with defense stocks, really can't hold them🥲"
