The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But in contrast you can make much more than 100% if the company does well. For example, the Sunflower Pharmaceutical Group Co.,Ltd (SZSE:002737) share price has soared 102% in the last three years. How nice for those who held the stock! Meanwhile the share price is 3.2% higher than it was a week ago.

On the back of a solid 7-day performance, let's check what role the company's fundamentals have played in driving long term shareholder returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Sunflower Pharmaceutical GroupLtd was able to grow its EPS at 33% per year over three years, sending the share price higher. The average annual share price increase of 26% is actually lower than the EPS growth. Therefore, it seems the market has moderated its expectations for growth, somewhat.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Sunflower Pharmaceutical GroupLtd the TSR over the last 3 years was 124%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that Sunflower Pharmaceutical GroupLtd shareholders have received a total shareholder return of 19% over the last year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 15%. 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. 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.
