By buying an index fund, you can roughly match the market return with ease. But if you choose individual stocks with prowess, you can make superior returns. For example, Supremex Inc. (TSE:SXP) shareholders have seen the share price rise 75% over three years, well in excess of the market return (13%, 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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Supremex was able to grow its EPS at 12% per year over three years, sending the share price higher. This EPS growth is lower than the 20% 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 three years ago. It's not unusual to see the market 're-rate' a stock, after a few years of growth.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Supremex's TSR for the last 3 years was 90%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in Supremex had a tough year, with a total loss of 32% (including dividends), against a market gain of about 15%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 15% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
