Pentair (NYSE:PNR) jumps 7.4% this week, though earnings growth is still tracking behind five-year shareholder returns

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. Long term Pentair plc (NYSE:PNR) shareholders would be well aware of this, since the stock is up 151% in five years. It's also good to see the share price up 17% over the last quarter.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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, Pentair managed to grow its earnings per share at 14% a year. This EPS growth is lower than the 20% 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. That's not necessarily surprising considering the five-year track record of earnings growth.

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 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, Pentair's TSR for the last 5 years was 171%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Pentair has rewarded shareholders with a total shareholder return of 40% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 22%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
