When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of USA Truck, Inc. (NASDAQ:USAK) stock is up an impressive 186% over the last five years. It's also up 46% in about a month. We note that USA Truck reported its financial results recently; luckily, you can catch up on the latest revenue and profit numbers in our company report.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the last half decade, USA Truck became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. Indeed, the USA Truck share price has gained 48% in three years. Meanwhile, EPS is up 25% per year. This EPS growth is higher than the 14% average annual increase in the share price over the same three years. So you might conclude the market is a little more cautious about the stock, these days. This cautious sentiment is reflected in its (fairly low) P/E ratio of 9.02.
