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 when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of MaxiPARTS Limited (ASX:MXI) stock is up an impressive 225% over the last five years.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the five years of share price growth, MaxiPARTS moved from a loss to profitability. 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.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Before buying or selling a stock, we always recommend a close examination of historic growth trends, available here..

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for MaxiPARTS the TSR over the last 5 years was 326%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 4.6% in the last year, MaxiPARTS shareholders lost 13% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 34%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand MaxiPARTS better, we need to consider many other factors. Consider risks, for instance.
