By buying an index fund, you can roughly match the market return with ease. But if you buy good businesses at attractive prices, your portfolio returns could exceed the average market return. Just take a look at Worley Limited (ASX:WOR), which is up 50%, over three years, soundly beating the market return of 7.5% (not including dividends).

So let's assess the underlying fundamentals over the last 3 years and see if they've moved in lock-step with shareholder returns.

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).

During three years of share price growth, Worley achieved compound earnings per share growth of 54% per year. This EPS growth is higher than the 14% average annual increase in the share price. Therefore, it seems the market has moderated its expectations for growth, somewhat.

You can see how EPS has changed over time in the image below (click on the chart to see the exact values).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Worley's TSR for the last 3 years was 66%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Investors in Worley had a tough year, with a total loss of 14% (including dividends), against a market gain of about 22%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 4%, each year, over five years. 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.
