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%. Long term Advanced Energy Industries, Inc. (NASDAQ:AEIS) shareholders would be well aware of this, since the stock is up 102% in five years. Also pleasing for shareholders was the 14% gain in the last three months.

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.

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 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 five years of share price growth, Advanced Energy Industries actually saw its EPS drop 1.4% per year.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The modest 0.4% dividend yield is unlikely to be propping up the share price. In contrast revenue growth of 17% per year is probably viewed as evidence that Advanced Energy Industries is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Advanced Energy Industries, it has a TSR of 105% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Advanced Energy Industries shareholders gained a total return of 2.2% during the year. Unfortunately this falls short of the market return. If we look back over five years, the returns are even better, coming in at 15% per year for five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
