It might be of some concern to shareholders to see the Energiekontor AG (ETR:EKT) share price down 12% in the last month. But that doesn't undermine the fantastic longer term performance (measured over five years). In that time, the share price has soared some 421% higher! Arguably, the recent fall is to be expected after such a strong rise. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price.

In light of the stock dropping 4.7% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Energiekontor achieved compound earnings per share (EPS) growth of 38% per year. This EPS growth is remarkably close to the 39% average annual increase in the share price. That suggests that the market sentiment around the company hasn't changed much over that time. Rather, the share price has approximately tracked EPS growth.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. It might be well worthwhile taking a look at our free report on Energiekontor's earnings, revenue and cash flow.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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 Energiekontor, it has a TSR of 467% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 18% in the last year, Energiekontor shareholders lost 12% (even including dividends). 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. On the bright side, long term shareholders have made money, with a gain of 41% per year over half a decade. 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. 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 1 warning sign for Energiekontor you should know about.
