Those who invested in Atmos Energy (NYSE:ATO) five years ago are up 71%

The main point of investing for the long term is to make money. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the Atmos Energy Corporation (NYSE:ATO) share price is up 51% in the last five years, that's less than the market return. However, more recent buyers should be happy with the increase of 31% over the last year.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. 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.

Over half a decade, Atmos Energy managed to grow its earnings per share at 9.1% a year. So the EPS growth rate is rather close to the annualized share price gain of 9% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Atmos Energy's TSR for the last 5 years was 71%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that Atmos Energy has rewarded shareholders with a total shareholder return of 35% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 11%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. It's always interesting to track share price performance over the longer term. But to understand Atmos Energy better, we need to consider many other factors. Consider risks, for instance.
