While Estun Automation Co., Ltd (SZSE:002747) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 19% in the last quarter. But that doesn't change the fact that the returns over the last five years have been pleasing. It has returned a market beating 90% in that time.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During five years of share price growth, Estun Automation achieved compound earnings per share (EPS) growth of 12% per year. So the EPS growth rate is rather close to the annualized share price gain of 14% per year. That suggests that the market sentiment around the company hasn't changed much over that time. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Estun Automation's TSR for the last 5 years was 93%, 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

We regret to report that Estun Automation shareholders are down 20% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 9.4%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 14% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
