The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, you can make far more than 100% on a really good stock. For example, the XPEL, Inc. (NASDAQ:XPEL) share price has soared 289% in the last half decade. Most would be very happy with that. It's also good to see the share price up 20% over the last quarter.

The past week has proven to be lucrative for XPEL investors, so let's see if fundamentals drove the company's five-year performance.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, XPEL achieved compound earnings per share (EPS) growth of 40% per year. This EPS growth is higher than the 31% average annual increase in the share price. Therefore, it seems the market has become relatively pessimistic about the company.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years. It might be well worthwhile taking a look at our free report on XPEL's earnings, revenue and cash flow.

A Different Perspective

While the broader market gained around 27% in the last year, XPEL shareholders lost 42%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 31%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
