In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term China Water Affairs Group Limited (HKG:855) shareholders, since the share price is down 49% in the last three years, falling well short of the market decline of around 18%. Furthermore, it's down 30% in about a quarter. That's not much fun for holders.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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 the three years that the share price fell, China Water Affairs Group's earnings per share (EPS) dropped by 4.0% each year. The share price decline of 20% is actually steeper than the EPS slippage. So it seems the market was too confident about the business, in the past. This increased caution is also evident in the rather low P/E ratio, which is sitting at 4.62.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for China Water Affairs Group the TSR over the last 3 years was -42%, 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

Investors in China Water Affairs Group had a tough year, with a total loss of 14% (including dividends), against a market gain of about 2.2%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 2% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
