Investing in CGN Power (HKG:1816) five years ago would have delivered you a 99% gain

When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, the CGN Power Co., Ltd. (HKG:1816) share price is up 57% in the last 5 years, clearly besting the market return of around 1.2% (ignoring dividends).

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

Check out our latest analysis for CGN Power

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 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.

Over half a decade, CGN Power managed to grow its earnings per share at 1.3% a year. This EPS growth is lower than the 9% 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.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized 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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. 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 99%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that CGN Power has rewarded shareholders with a total shareholder return of 62% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 15% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
