Cosmax (KRX:192820) jumps 19% this week, though earnings growth is still tracking behind five-year shareholder returns

It hasn't been the best quarter for Cosmax, Inc. (KRX:192820) shareholders, since the share price has fallen 18% in that time. But in stark contrast, the returns over the last half decade have impressed. We think most investors would be happy with the 101% return, over that period. 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.

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 paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Cosmax achieved compound earnings per share (EPS) growth of 17% per year. This EPS growth is reasonably close to the 15% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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 Cosmax, it has a TSR of 109% 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

It's nice to see that Cosmax shareholders have received a total shareholder return of 14% over the last year. That's including the dividend. However, that falls short of the 16% TSR per annum it has made for shareholders, each year, over five years. 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.
