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%. For instance the Archrock, Inc. (NYSE:AROC) share price is 126% higher than it was three years ago. That sort of return is as solid as granite. Better yet, the share price has risen 3.4% in the last week.

The past week has proven to be lucrative for Archrock investors, so let's see if fundamentals drove the company's three-year performance.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Archrock became profitable within the last three years. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

It is of course excellent to see how Archrock has grown profits over the years, but the future is more important for shareholders. It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

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. We note that for Archrock the TSR over the last 3 years was 169%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that Archrock shareholders have received a total shareholder return of 102% over the last year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 22% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Take risks, for example - Archrock has 2 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
