Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, long term China Yangtze Power Co., Ltd. (SHSE:600900) shareholders have enjoyed a 47% share price rise over the last half decade, well in excess of the market return of around 18% (not including dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 18% , including dividends .

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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. 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 Yangtze Power achieved compound earnings per share (EPS) growth of 61% per year. This EPS growth is higher than the 8% average annual increase in the share price. So one could conclude that the broader market has become more cautious towards the stock. This cautious sentiment is reflected in its (fairly low) P/E ratio of 2.13.

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). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for China Yangtze Power the TSR over the last 5 years was 77%, 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

We're pleased to report that China Yangtze Power shareholders have received a total shareholder return of 18% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 12%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
