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 Preformed Line Products Company (NASDAQ:PLPC) which saw its share price drive 147% higher over five years. But it's down 8.1% in the last week. It may be that the recent financial results disappointed, so check out the latest revenue and profit numbers on in our company report.'

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

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. 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.

During five years of share price growth, Preformed Line Products achieved compound earnings per share (EPS) growth of 11% per year. This EPS growth is slower than the share price growth of 20% per year, over the same period. 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.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Preformed Line Products, it has a TSR of 160% 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

Investors in Preformed Line Products had a tough year, with a total loss of 27% (including dividends), against a market gain of about 14%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 21%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. It's always interesting to track share price performance over the longer term. But to understand Preformed Line Products better, we need to consider many other factors. Consider risks, for instance.
