Boeing, GE Aerospace, and Rocket Lab are the three Defense stocks to watch today, according to MarketBeat’s stock screener tool. Defense stocks are shares of companies that design, manufacture, or provide services and technology for military and national security purposes—for example, aerospace contractors, weapons makers, and defense-focused IT firms. Investors often view them as relatively stable because government defense spending tends to be steady and less sensitive to economic cycles, though they still carry company-specific and policy-related risks. These companies had the highest dollar trading volume of any Defense stocks within the last several days.
