By buying an index fund, investors can approximate the average market return. But if you buy good businesses at attractive prices, your portfolio returns could exceed the average market return. For example, Robert Half International Inc. (NYSE:RHI) shareholders have seen the share price rise 55% over three years, well in excess of the market return (37%, not including dividends).

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During three years of share price growth, Robert Half International achieved compound earnings per share growth of 11% per year. This EPS growth is lower than the 16% 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. That's not necessarily surprising considering the three-year track record of earnings growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. As it happens, Robert Half International's TSR for the last 3 years was 64%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 4.4% in the last year, Robert Half International shareholders lost 18% (even including dividends). 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. On the bright side, long term shareholders have made money, with a gain of 4.5% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
