Investors five-year returns in Energiekontor (ETR:EKT) have not grown faster than the company's underlying earnings growth

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 on the bright side, you can make far more than 100% on a really good stock. For example, the Energiekontor AG (ETR:EKT) share price has soared 111% in the last half decade. Most would be very happy with that. But it's down 8.1% in the last week.

While the stock has fallen 8.1% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying 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, Energiekontor managed to grow its earnings per share at 149% a year. The EPS growth is more impressive than the yearly share price gain of 16% over the same period. So it seems the market isn't so enthusiastic about the stock these days.

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.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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, Energiekontor's TSR for the last 5 years was 123%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 20% in the last year, Energiekontor shareholders lost 37% (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. Longer term investors wouldn't be so upset, since they would have made 17%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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. Like risks, for instance. Every company has them, and we've spotted 4 warning signs for Energiekontor (of which 1 makes us a bit uncomfortable!) you should know about.
