The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But when you pick a company that is really flourishing, you can make more than 100%. For instance the T&S Communications Co.,Ltd. (SZSE:300570) share price is 172% higher than it was three years ago. How nice for those who held the stock! Better yet, the share price has risen 23% in the last week.

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.

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).

T&S CommunicationsLtd was able to grow its EPS at 28% per year over three years, sending the share price higher. This EPS growth is lower than the 40% average annual increase in the share price. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. That's not necessarily surprising considering the three-year track record of earnings growth. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 57.30.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of T&S CommunicationsLtd, it has a TSR of 185% for the last 3 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

We're pleased to report that T&S CommunicationsLtd shareholders have received a total shareholder return of 38% over one year. Of course, that includes the dividend. That's better than the annualised return of 13% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
