Rocket Lab, Boeing, GE Aerospace, Syntec Optics, RTX, Intuitive Machines, and Lockheed Martin are the seven Defense stocks to watch today, according to MarketBeat’s stock screener tool. Defense stocks are shares of companies that design, produce, or service military and national-security-related equipment and technologies—such as aircraft, weapons systems, satellites, and cybersecurity and defense contracting services. Investors often view them as relatively defensive because government defense spending tends to be more stable across economic cycles and can increase during geopolitical tensions, making these stocks less sensitive to typical recessions (though they still carry policy, budget and contract risks). These companies had the highest dollar trading volume of any Defense stocks within the last several days.
