Rocket Lab, GE Aerospace, Boeing, Lockheed Martin, and RTX are the five Defense stocks to watch today, according to MarketBeat’s stock screener tool. Defense stocks are shares of companies that design, manufacture, or provide services for military and national security needs—things like weapons, aircraft, naval vessels, satellites, and defense-related software and cybersecurity. Investors often treat them as defensive holdings because government contracts and steady defense budgets can make their revenues and dividends relatively stable through economic downturns, though they remain exposed to policy, budget, and geopolitical risks. These companies had the highest dollar trading volume of any Defense stocks within the last several days.
