When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of AAON, Inc. (NASDAQ:AAON) stock is up an impressive 106% over the last five years. Also pleasing for shareholders was the 42% gain in the last three months.

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.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

Over half a decade, AAON managed to grow its earnings per share at 6.0% a year. This EPS growth is lower than the 16% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 60.34.

The image below shows how EPS has tracked over time (if you click on the image you can see greater detail).

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. 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. In the case of AAON, it has a TSR of 113% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that AAON shareholders have received a total shareholder return of 8.1% over one year. Of course, that includes the dividend. Having said that, the five-year TSR of 16% a year, is even better. The pessimistic view would be that be that the stock has its best days behind it, but on the other hand the price might simply be moderating while the business itself continues to execute. 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.
