By buying an index fund, investors can approximate the average market return. But many of us dare to dream of bigger returns, and build a portfolio ourselves. For example, GrainCorp Limited (ASX:GNC) shareholders have seen the share price rise 31% over three years, well in excess of the market return (4.5%, not including dividends).

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, GrainCorp achieved compound earnings per share growth of 135% per year. This EPS growth is higher than the 9% average annual increase in the share price. So it seems investors have become more cautious about the company, over time.

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, GrainCorp's TSR for the last 3 years was 56%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's nice to see that GrainCorp shareholders have received a total shareholder return of 34% over the last year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 25%. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
