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 Pentair plc (NYSE:PNR) stock is up an impressive 102% over the last five years. The last week saw the share price soften some 2.2%.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

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.

During five years of share price growth, Pentair achieved compound earnings per share (EPS) growth of 15% per year. That makes the EPS growth particularly close to the yearly share price growth of 15%. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

We know that Pentair has improved its bottom line lately, but is it going to grow revenue? This freereport showing analyst revenue forecasts should help you figure out if the EPS growth can be sustained.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Pentair, it has a TSR of 119% 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

We're pleased to report that Pentair shareholders have received a total shareholder return of 47% over one year. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 17% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand Pentair better, we need to consider many other factors. Consider risks, for instance. Every company has them, and we've spotted  1 warning sign for Pentair  you should know about.
