Fourth-quarter profits for FedEx (FDX 2.26%) came in higher than expected, and shares rose on the news. Often considered a bellwether for the economy, FedEx is the world's biggest air-freight company. The company's size, along with barriers to entry in the industry, give it the power to raise rates, which it also announced for its FedEx Freight service. That said, some investors are concerned that FedEx's decision to cut some routes between the United States and Asia will hamper future growth. In this installment of Stock of the Day, Motley Fool analyst Jason Moser shares why the long-term growth of e-commerce will continue to pay dividends for FedEx.
