When we invest, we're generally looking for stocks that outperform the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, long term Sumec Corporation Limited (SHSE:600710) shareholders have enjoyed a 69% share price rise over the last half decade, well in excess of the market return of around 19% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 32% in the last year, including dividends.

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, Sumec achieved compound earnings per share (EPS) growth of 16% per year. The EPS growth is more impressive than the yearly share price gain of 11% over the same period. So one could conclude that the broader market has become more cautious towards the stock. This cautious sentiment is reflected in its (fairly low) P/E ratio of 10.56.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Sumec the TSR over the last 5 years was 103%, 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

It's good to see that Sumec has rewarded shareholders with a total shareholder return of 32% in the last twelve months. And that does include 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for Sumec you should know about.
