The five-year decline in earnings might be taking its toll on CGN Power (HKG:1816) shareholders as stock falls 3.1% over the past week

CGN Power Co., Ltd. (HKG:1816) shareholders have seen the share price descend 10% over the month. But that doesn't change the fact that the returns over the last five years have been pleasing. After all, the share price is up a market-beating 76% in that time.

Although CGN Power has shed HK$4.5b from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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).

CGN Power's earnings per share are down 0.3% per year, despite strong share price performance over five years.

By glancing at these numbers, we'd posit that the decline in earnings per share is not representative of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

On the other hand, CGN Power's revenue is growing nicely, at a compound rate of 4.4% over the last five years. In that case, the company may be sacrificing current earnings per share to drive growth.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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 CGN Power the TSR over the last 5 years was 122%, 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

CGN Power shareholders are up 5.6% for the year (even including dividends). But that return falls short of the market. If we look back over five years, the returns are even better, coming in at 17% per year for five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
