Rocket Lab, GE Aerospace, and Boeing are the three Defense stocks to watch today, according to MarketBeat’s stock screener tool. Defense stocks are shares of companies that manufacture military equipment, aircraft, weapons systems, and provide related services (such as cybersecurity, logistics, and maintenance) and typically derive significant revenue from government defense contracts. Investors view them as relatively defensive because demand for defense spending tends to be steadier across economic cycles, which can lead to more predictable cash flows and lower sensitivity to broad market downturns. These companies had the highest dollar trading volume of any Defense stocks within the last several days.
