The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. One great example is NARI Technology Co., Ltd. (SHSE:600406) which saw its share price drive 129% higher over five years. Meanwhile the share price is 1.8% higher than it was a week ago.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders 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, NARI Technology achieved compound earnings per share (EPS) growth of 11% per year. This EPS growth is lower than the 18% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. We note that for NARI Technology the TSR over the last 5 years was 147%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that NARI Technology shareholders have received a total shareholder return of 5.4% over one year. And that does include the dividend. Having said that, the five-year TSR of 20% a year, is even better. Potential buyers might understandably feel they've missed the opportunity, but it's always possible business is still firing on all cylinders. 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.
