The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Hengdian Group DMEGC Magnetics Co. ,Ltd (SZSE:002056) stock is up an impressive 113% over the last five years. In the last week the share price is up 1.9%.

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. 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).

Over half a decade, Hengdian Group DMEGC Magnetics Ltd managed to grow its earnings per share at 19% a year. So the EPS growth rate is rather close to the annualized share price gain of 16% per year. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Hengdian Group DMEGC Magnetics Ltd the TSR over the last 5 years was 131%, 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 regret to report that Hengdian Group DMEGC Magnetics Ltd shareholders are down 18% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 8.7%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 18%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
