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 example, the Rush Enterprises, Inc. (NASDAQ:RUSH.A) share price has soared 188% in the last half decade. Most would be very happy with that. In more good news, the share price has risen 14% in thirty days. This could be related to the recent financial results that were recently released - you could check the most recent data by reading our company report.

While the stock has fallen 3.2% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

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.

Over half a decade, Rush Enterprises managed to grow its earnings per share at 15% a year. This EPS growth is slower than the share price growth of 24% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Rush Enterprises, it has a TSR of 211% 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

It's good to see that Rush Enterprises has rewarded shareholders with a total shareholder return of 56% in the last twelve months. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 25%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
