Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. Buying under-rated businesses is one path to excess returns. For example, the Sinoma International Engineering Co.,Ltd (SHSE:600970) share price is up 70% in the last 5 years, clearly besting the market return of around 16% (ignoring dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 4.7% in the last year, including dividends.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, Sinoma International EngineeringLtd managed to grow its earnings per share at 5.5% a year. This EPS growth is lower than the 11% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. 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. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Sinoma International EngineeringLtd, it has a TSR of 99% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Sinoma International EngineeringLtd shareholders gained a total return of 4.7% during the year. Unfortunately this falls short of the market return. If we look back over five years, the returns are even better, coming in at 15% per year for five years. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Sinoma International EngineeringLtd you should know about.
