After watching Caterpillar (NYSE:CAT) stock gain more than 8% over the past three months, investors may be wondering whether there's room for more upside. After all, the mining industry is yet to show any signs of revival, and just days back, bellwether Alcoa (NYSE:AA) sounded the warning for a key end market that Caterpillar's energy and transportation business caters to.
