In the video below, Motley Fool industrials analyst Blake Bos takes a question posted on Facebook about Caterpillar (CAT 1.39%) from a Motley Fool reader, who writes: "What's the two year outlook? I am so confused about where their revenue comes from. They make truck engines, locomotives, mining, agriculture, they have too many competitors for me to understand where they are strong, weak, improving or falling behind. What do I do with my CAT? Move the dollars to my mutual fund? It is all in a Roth IRA."
