Execution and Supply Risks Remain While Boeing's Planes Are Still in Strong Demand

Boeing is a major aerospace and defense firm that makes most of its money manufacturing large commercial airplanes. Its narrow-bodied planes are ideal for high-frequency, short-haul routes, and its wide-bodied ones are used for long-haul and transcontinental flights. Worldwide sales of narrow-bodies have increased over the past 20 years with the rise of low-cost carriers and middle-class consumers in emerging markets.
