Tze Shin International (TWSE:2611) jumps 11% this week, though earnings growth is still tracking behind five-year shareholder returns

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 the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Tze Shin International Co., Ltd. (TWSE:2611) share price has soared 209% in the last half decade. Most would be very happy with that. And in the last month, the share price has gained 23%.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last half decade, Tze Shin International became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains.

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. As it happens, Tze Shin International's TSR for the last 5 years was 242%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that Tze Shin International shareholders have received a total shareholder return of 38% over the last year. And that does include the dividend. That's better than the annualised return of 28% 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. 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.
