It hasn't been the best quarter for AMA Group Limited (ASX:AMA) shareholders, since the share price has fallen 27% in that time. But in stark contrast, the returns over the last half decade have impressed. Indeed, the share price is up an impressive 174% in that time. So while it's never fun to see a share price fall, it's important to look at a longer time horizon. The more important question is whether the stock is too cheap or too expensive today.

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 five years of share price growth, AMA Group achieved compound earnings per share (EPS) growth of 18% per year. This EPS growth is slower than the share price growth of 22% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. That's not necessarily surprising considering the five-year track record of earnings growth.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. As it happens, AMA Group's TSR for the last 5 years was 217%, 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

AMA Group provided a TSR of 9.6% over the last twelve months. But that return falls short of the market. It's probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 26% over 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. 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.
