Alerion Clean Power (BIT:ARN) jumps 5.3% 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 when you pick a company that is really flourishing, you can make more than 100%. One great example is Alerion Clean Power S.p.A. (BIT:ARN) which saw its share price drive 137% higher over five years. Better yet, the share price has risen 5.3% in the last week.

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, Alerion Clean Power achieved compound earnings per share (EPS) growth of 31% per year. The EPS growth is more impressive than the yearly share price gain of 19% over the same period. So it seems the market isn't so enthusiastic about the stock these days.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Alerion Clean Power the TSR over the last 5 years was 170%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Alerion Clean Power provided a TSR of 16% over the last twelve months. Unfortunately this falls short of the market return. On the bright side, the longer term returns (running at about 22% a year, over half a decade) look better. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
