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 73% in the last 5 years, clearly besting the market return of around 33% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 19% , including dividends .

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

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just 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.

Over half a decade, SDIC Power Holdings managed to grow its earnings per share at 7.1% a year. This EPS growth is lower than the 12% 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. That's not necessarily surprising considering the five-year track record of earnings 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 95%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that SDIC Power Holdings has rewarded shareholders with a total shareholder return of 19% in the last twelve months. And that does include the dividend. That's better than the annualised return of 14% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
