When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of SDIC Power Holdings Co., Ltd (SHSE:600886) stock is up an impressive 116% over the last five years. On top of that, the share price is up 19% in about a quarter.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 half a decade, SDIC Power Holdings managed to grow its earnings per share at 8.8% a year. This EPS growth is lower than the 17% average annual increase in the share price. So it's fair to assume the market has a higher opinion of the business than it did five years ago. And that's hardly shocking given the track record of growth.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for SDIC Power Holdings the TSR over the last 5 years was 144%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that SDIC Power Holdings shareholders have received a total shareholder return of 42% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 20% per year), it would seem that the stock's performance has improved in recent times. 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.
