Investors in Naturgy Energy Group (BME:NTGY) have seen solid returns of 102% over the past five years

When you buy and hold a stock for the long term, you definitely want it to provide a positive return. Better yet, you'd like to see the share price move up more than the market average. But Naturgy Energy Group, S.A. (BME:NTGY) has fallen short of that second goal, with a share price rise of 59% over five years, which is below the market return. Looking at the last year alone, the stock is up 15%.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

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 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, Naturgy Energy Group achieved compound earnings per share (EPS) growth of 14% per year. This EPS growth is higher than the 10% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock.

It's probably worth noting that the CEO is paid less than the median at similar sized companies.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Naturgy Energy Group the TSR over the last 5 years was 102%, 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

Naturgy Energy Group shareholders gained a total return of 21% during the year. But that return falls short of the market. The silver lining is that the gain was actually better than the average annual return of 15% per year over five year. This suggests the company might be improving over time. 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.
