Pentair plc (NYSE:PNR) shareholders might be concerned after seeing the share price drop 18% in the last quarter. But that doesn't change the fact that shareholders have received really good returns over the last five years. We think most investors would be happy with the 162% return, over that period. Generally speaking the long term returns will give you a better idea of business quality than short periods can. Ultimately business performance will determine whether the stock price continues the positive long term trend.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Over half a decade, Pentair managed to grow its earnings per share at 12% a year. This EPS growth is lower than the 21% average annual increase in the share price. 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). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Pentair, it has a TSR of 180% 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

Pentair shareholders are up 3.4% for the year (even including dividends). But that return falls short of the market. On the bright side, the longer term returns (running at about 23% a year, over half a decade) look better. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. 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 Pentair you should know about.
