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 the bright side, you can make far more than 100% on a really good stock. For instance, the price of Group 1 Automotive, Inc. (NYSE:GPI) stock is up an impressive 249% over the last five years. Also pleasing for shareholders was the 14% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 11% in 90 days).

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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 five years of share price growth, Group 1 Automotive achieved compound earnings per share (EPS) growth of 40% per year. The EPS growth is more impressive than the yearly share price gain of 28% over the same period. Therefore, it seems the market has become relatively pessimistic about the company. The reasonably low P/E ratio of 6.94 also suggests market apprehension.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Group 1 Automotive, it has a TSR of 263% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Group 1 Automotive shareholders gained a total return of 19% during the year. But that was short of the market average. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 29% over five years. Maybe the share price is just taking a breather while the business executes on its growth strategy. 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.
