Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. Buying under-rated businesses is one path to excess returns. For example, long term Zhejiang Asia-Pacific Mechanical & Electronic Co.,Ltd (SZSE:002284) shareholders have enjoyed a 47% share price rise over the last half decade, well in excess of the market return of around 2.2% (not including dividends).

Since it's been a strong week for Zhejiang Asia-Pacific Mechanical & ElectronicLtd shareholders, let's have a look at trend of the longer term fundamentals.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 the last half decade, Zhejiang Asia-Pacific Mechanical & ElectronicLtd became profitable. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Zhejiang Asia-Pacific Mechanical & ElectronicLtd share price is down 1.4% in the last three years. Meanwhile, EPS is up 27% per year. It would appear there's a real mismatch between the increasing EPS and the share price, which has declined -0.5% a year for three years.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Zhejiang Asia-Pacific Mechanical & ElectronicLtd, it has a TSR of 52% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market lost about 17% in the twelve months, Zhejiang Asia-Pacific Mechanical & ElectronicLtd shareholders did even worse, losing 33% (even including dividends). 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. On the bright side, long term shareholders have made money, with a gain of 9% 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. 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.
