The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But if you buy shares in a really great company, you can more than double your money. For instance the Changgao Electric Group Co., Ltd. (SZSE:002452) share price is 118% higher than it was three years ago. Most would be happy with that. It's also good to see the share price up 35% over the last quarter.

In light of the stock dropping 6.2% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive three-year return.

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 is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Changgao Electric Group's TSR for the last 3 years was 126%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that Changgao Electric Group has rewarded shareholders with a total shareholder return of 52% in the last twelve months. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 5% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
