China Datang Corporation Renewable Power (HKG:1798) jumps 3.8% this week, though earnings growth is still tracking behind five-year shareholder returns

When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. One great example is China Datang Corporation Renewable Power Co., Limited (HKG:1798) which saw its share price drive 149% higher over five years. In more good news, the share price has risen 16% in thirty days. But the price may well have benefitted from a buoyant market, since stocks have gained 7.7% in the last thirty days.

Since it's been a strong week for China Datang Corporation Renewable Power shareholders, let's have a look at trend of the longer term 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. 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, China Datang Corporation Renewable Power achieved compound earnings per share (EPS) growth of 16% per year. This EPS growth is lower than the 20% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

The graphic below depicts how EPS has changed over time (unveil the exact values by clicking on the image).

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, China Datang Corporation Renewable Power's TSR for the last 5 years was 178%, 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

Investors in China Datang Corporation Renewable Power had a tough year, with a total loss of 34% (including dividends), against a market gain of about 10.0%. 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. On the bright side, long term shareholders have made money, with a gain of 23% 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.
