When you buy a stock there is always a possibility that it could drop 100%. But on the bright side, you can make far more than 100% on a really good stock. One great example is Republic Services, Inc. (NYSE:RSG) which saw its share price drive 104% higher over five years. It's down 2.6% in the last seven days.

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.

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. 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, Republic Services managed to grow its earnings per share at 4.0% a year. This EPS growth is lower than the 15% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Republic Services' TSR for the last 5 years was 121%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Republic Services shareholders are up 8.9% for the year (even including dividends). Unfortunately this falls short of the market return. On the bright side, the longer term returns (running at about 17% a year, over half a decade) look better. 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.
