President Donald Trump’s plans for a ” Golden Dome ” missile defense system could be a catalyst for a handful of stocks. On Tuesday, Trump unveiled details of the defense system. He forecast that the project would be complete before the end of his term and estimated that the total cost of the project would be $175 billion. He said that an initial $25 billion would be earmarked in a sweeping spending package , which is currently being weighed by Congress. The Golden Dome is similar to Israel’s missile deterrent system, the so-called “Iron Dome,” which has been in use since 2011. Analysts on Wall Street were already optimistic on shares of defense and aerospace giants RTX , Northrop Grumman and Lockheed Martin before Trump’s Tuesday announcement. Lockheed and RTX were among the companies name-checked during the event , as was L3Harris Technologies . The stock reaction so far has been largely lackluster following Trump’s press conference, as the broader market traded lower on Wednesday . Shares of Lockheed, RTX and Northrop were marginally lower. L3Harris bucked the trend with a gain of about 1%. “The program details remain scarce, but with a 4-star general appointed (General Michael Guetlein) to lead the effort, the level of importance to the administration is obvious. The $25B in the Reconciliation Bill and President Trump’s sizing of the program at $175B also underscore the program’s significance,” Wolfe Research analyst Myles Walton wrote in a Tuesday note.
