By buying an index fund, you can roughly match the market return with ease. But if you choose individual stocks with prowess, you can make superior returns. For example, the Wangsu Science & Technology Co.,Ltd. (SZSE:300017) share price is up 54% in the last three years, clearly besting the market decline of around 14% (not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 37%, including dividends.

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.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, Wangsu Science & TechnologyLtd achieved compound earnings per share growth of 60% per year. This EPS growth is higher than the 15% average annual increase in the share price. Therefore, it seems the market has moderated its expectations for growth, somewhat.

The company's earnings per share (over time) is depicted in the image below (click to see the exact numbers).

We know that Wangsu Science & TechnologyLtd has improved its bottom line over the last three years, but what does the future have in store? You can see how its balance sheet has strengthened (or weakened) over time in this free interactive graphic.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Wangsu Science & TechnologyLtd, it has a TSR of 60% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Wangsu Science & TechnologyLtd has rewarded shareholders with a total shareholder return of 37% in the last twelve months. That's including the dividend. That gain is better than the annual TSR over five years, which is 3%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Wangsu Science & TechnologyLtd better, we need to consider many other factors.
