The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But in contrast you can make much more than 100% if the company does well. To wit, the China Shenhua Energy Company Limited (HKG:1088) share price has flown 101% in the last three years. Most would be happy with that. It's also good to see the share price up 20% over the last quarter.

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

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

China Shenhua Energy was able to grow its EPS at 18% per year over three years, sending the share price higher. This EPS growth is lower than the 26% average annual increase in the share price. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. That's not necessarily surprising considering the three-year track record of earnings growth.

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. 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 Shenhua Energy the TSR over the last 3 years was 193%, 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

It's nice to see that China Shenhua Energy shareholders have received a total shareholder return of 46% over the last year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 21%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
