Chang Wah Electromaterials (TWSE:8070) sheds 6.7% this week, as yearly returns fall more in line with earnings growth

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Chang Wah Electromaterials Inc. (TWSE:8070) stock is up an impressive 168% over the last five years. But it's down 6.7% in the last week. However, this might be related to the overall market decline of 4.2% in a week.

While the stock has fallen 6.7% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, Chang Wah Electromaterials achieved compound earnings per share (EPS) growth of 7.0% per year. This EPS growth is slower than the share price growth of 22% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of 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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Chang Wah Electromaterials the TSR over the last 5 years was 261%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that Chang Wah Electromaterials shareholders have received a total shareholder return of 49% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 29% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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 for instance, the ever-present spectre of investment risk.
