Despite delivering investors losses of 17% over the past 5 years, WEX (NYSE:WEX) has been growing its earnings

The main aim of stock picking is to find the market-beating stocks. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term WEX Inc. (NYSE:WEX) shareholders for doubting their decision to hold, with the stock down 17% over a half decade. In the last ninety days we've seen the share price slide 25%.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

In contrast to the share price, revenue has actually increased by 12% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 3% endured over half a decade. So this might be a sign the business has turned its fortunes around. It's always interesting to track share price performance over the longer term. But to understand WEX better, we need to consider many other factors.
