Check out our latest analysis for China Merchants Shekou Industrial Zone Holdings

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 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).

Looking back five years, both China Merchants Shekou Industrial Zone Holdings' share price and EPS declined; the latter at a rate of 27% per year. The share price decline of 10% per year isn't as bad as the EPS decline. So investors might expect EPS to bounce back -- or they may have previously foreseen the EPS decline.

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, China Merchants Shekou Industrial Zone Holdings' TSR for the last 5 years was -30%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that China Merchants Shekou Industrial Zone Holdings shareholders are down 25% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 3.8%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 5% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business.
