Sailun Group Co., Ltd. (SHSE:601058) shareholders might be concerned after seeing the share price drop 12% in the last month. But that does not change the realty that the stock's performance has been terrific, over five years. Indeed, the share price is up a whopping 374% in that time. So we don't think the recent decline in the share price means its story is a sad one. Of course what matters most is whether the business can improve itself sustainably, thus justifying a higher price.

Although Sailun Group has shed CN¥1.4b from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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 five years of share price growth, Sailun Group achieved compound earnings per share (EPS) growth of 33% per year. So the EPS growth rate is rather close to the annualized share price gain of 36% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. In fact, the share price seems to largely reflect the EPS growth.

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, Sailun Group's TSR for the last 5 years was 408%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Sailun Group has rewarded shareholders with a total shareholder return of 43% in the last twelve months. And that does include the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 38% per year), it would seem that the stock's performance has improved in recent times. 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.
