The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. For example, the New East New Materials Co., Ltd (SHSE:603110) share price has soared 298% in the last half decade. Most would be very happy with that. It's also good to see the share price up 27% over the last quarter.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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.

New East New Materials' earnings per share are down 14% per year, despite strong share price performance over five years.

Essentially, it doesn't seem likely that investors are focused on EPS. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

The modest 0.5% dividend yield is unlikely to be propping up the share price. We are not particularly impressed by the annual compound revenue growth of 0.8% over five years. So why is the share price up? It's not immediately obvious to us, but a closer look at the company's progress over time might yield answers.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, New East New Materials' TSR for the last 5 years was 323%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 6.7% in the twelve months, New East New Materials shareholders did even worse, losing 11% (even including dividends). 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 33%, 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.
