The 8.1% return this week takes Argan's (NYSE:AGX) shareholders five-year gains to 433%

Long term investing can be life changing when you buy and hold the truly great businesses. While not every stock performs well, when investors win, they can win big. Just think about the savvy investors who held Argan, Inc. (NYSE:AGX) shares for the last five years, while they gained 358%. And this is just one example of the epic gains achieved by some long term investors. It's also up 36% in about a month.

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.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

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 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 the last half decade, Argan became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Argan share price is up 343% in the last three years. In the same period, EPS is up 37% per year. This EPS growth is lower than the 64% average annual increase in the share price over three years. So one can reasonably conclude the market is more enthusiastic about the stock than it was three years ago.

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

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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 Argan the TSR over the last 5 years was 433%, 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

We're pleased to report that Argan shareholders have received a total shareholder return of 172% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 40%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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. Consider risks, for instance.
