When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, the SDIC Power Holdings Co., Ltd (SHSE:600886) share price is up 80% in the last 5 years, clearly besting the market return of around 19% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 28%, including dividends.

The past week has proven to be lucrative for SDIC Power Holdings investors, so let's see if fundamentals drove the company's five-year performance.

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...' 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, SDIC Power Holdings achieved compound earnings per share (EPS) growth of 6.7% per year. This EPS growth is lower than the 12% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

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, SDIC Power Holdings' TSR for the last 5 years was 104%, 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 nice to see that SDIC Power Holdings shareholders have received a total shareholder return of 28% over the last year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 15%. Therefore it seems like sentiment around the company has been positive lately. 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. Take risks, for example - SDIC Power Holdings has 2 warning signs (and 1 which is a bit concerning) we think you should know about.
