The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For instance, the price of REV Group, Inc. (NYSE:REVG) stock is up an impressive 210% over the last five years. It's also good to see the share price up 25% over the last quarter.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

Check out our latest analysis for REV Group

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 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.

During the last half decade, REV Group became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. We can see that the REV Group share price is up 133% in the last three years. During the same period, EPS grew by 92% each year. This EPS growth is higher than the 33% average annual increase in the share price over the same three years. Therefore, it seems the market has moderated its expectations for growth, somewhat. This unenthusiastic sentiment is reflected in the stock's reasonably modest P/E ratio of 6.70.

We know that REV Group has improved its bottom line over the last three years, but what does the future have in store? Take a more thorough look at REV Group's financial health with this free report on its balance sheet.

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. As it happens, REV Group's TSR for the last 5 years was 290%, 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 REV Group has rewarded shareholders with a total shareholder return of 129% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 31% 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. 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. Consider risks, for instance. Every company has them, and we've spotted 2 warning signs for REV Group you should know about.
