It hasn't been the best quarter for Do-Fluoride New Materials Co., Ltd. (SZSE:002407) shareholders, since the share price has fallen 15% in that time. But that doesn't change the fact that shareholders have received really good returns over the last five years. In fact, the share price is 154% higher today. We think it's more important to dwell on the long term returns than the short term returns. Of course, that doesn't necessarily mean it's cheap now. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 38% drop, in the last year.

Since the stock has added CN¥777m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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).

During the last half decade, Do-Fluoride New Materials became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

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 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. In the case of Do-Fluoride New Materials, it has a TSR of 171% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market lost about 0.6% in the twelve months, Do-Fluoride New Materials shareholders did even worse, losing 37% (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 22%, 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.
