When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Republic Services, Inc. (NYSE:RSG) share price has soared 128% in the last half decade. Most would be very happy with that.

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 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 five years of share price growth, Republic Services achieved compound earnings per share (EPS) growth of 13% per year. This EPS growth is slower than the share price growth of 18% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. 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. This free interactive report on Republic Services' earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

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 145%, 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 have received returns of 27% over twelve months (even including dividends), which isn't far from the general market return. That gain looks pretty satisfying, and it is even better than the five-year TSR of 20% per year. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. 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. Consider risks, for instance. Every company has them, and we've spotted 2 warning signs for Republic Services you should know about.
