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%. Long term Shijiazhuang Kelin Electric Co., Ltd. (SHSE:603050) shareholders would be well aware of this, since the stock is up 294% in five years. It's also good to see the share price up 103% over the last quarter.

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

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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 five years of share price growth, Shijiazhuang Kelin Electric achieved compound earnings per share (EPS) growth of 35% per year. This EPS growth is reasonably close to the 32% average annual increase in the share price. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Rather, the share price has approximately tracked EPS growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Shijiazhuang Kelin Electric, it has a TSR of 328% 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

It's good to see that Shijiazhuang Kelin Electric has rewarded shareholders with a total shareholder return of 105% in the last twelve months. That's including the dividend. That gain is better than the annual TSR over five years, which is 34%. Therefore it seems like sentiment around the company has been positive lately. 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.
