The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Triumph Science & Technology Co.,Ltd (SHSE:600552) stock is up an impressive 106% over the last five years. On the other hand, the stock price has retraced 5.8% in the last week. But this could be related to the soft market, with stocks selling off around 2.7% in the last week.

Although Triumph Science & TechnologyLtd has shed CN¥690m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven 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 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, Triumph Science & TechnologyLtd achieved compound earnings per share (EPS) growth of 6.6% per year. This EPS growth is slower than the share price growth of 16% per year, over the same period. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 109.83.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Triumph Science & TechnologyLtd, it has a TSR of 114% for the last 5 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

While it's certainly disappointing to see that Triumph Science & TechnologyLtd shares lost 13% throughout the year, that wasn't as bad as the market loss of 17%. Of course, the long term returns are far more important and the good news is that over five years, the stock has returned 16% for each year. In the best case scenario the last year is just a temporary blip on the journey to a brighter future. 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.
