The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. To wit, the GD Power Development Co.,Ltd (SHSE:600795) share price has flown 106% in the last three years. Most would be happy with that. In the last week shares have slid back 1.3%.

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with 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).

Over the last three years, GD Power DevelopmentLtd failed to grow earnings per share, which fell 0.08% (annualized).

Based on these numbers, we think that the decline in earnings per share may not be a good representation of how the business has changed over the years. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

It could be that the revenue growth of 5.2% per year is viewed as evidence that GD Power DevelopmentLtd is growing. In that case, the company may be sacrificing current earnings per share to drive growth, and maybe shareholder's faith in better days ahead will be rewarded.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, GD Power DevelopmentLtd's TSR for the last 3 years was 119%, 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 GD Power DevelopmentLtd shareholders have received a total shareholder return of 36% over the last year. Of course, that includes the dividend. That's better than the annualised return of 18% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
