By buying an index fund, you can roughly match the market return with ease. But many of us dare to dream of bigger returns, and build a portfolio ourselves. For example, PC Connection, Inc. (NASDAQ:CNXN) shareholders have seen the share price rise 66% over three years, well in excess of the market return (22%, not including dividends). On the other hand, the returns haven't been quite so good recently, with shareholders up just 13%, including dividends.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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 three years of share price growth, PC Connection achieved compound earnings per share growth of 12% per year. In comparison, the 18% per year gain in the share price outpaces the EPS growth. 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.

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 that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward. It might be well worthwhile taking a look at our free report on PC Connection's earnings, revenue and cash flow.

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, PC Connection's TSR for the last 3 years was 70%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

PC Connection shareholders gained a total return of 13% during the year. But that was short of the market average. On the bright side, that's still a gain, and it's actually better than the average return of 10% over half a decade This suggests the company might be improving over 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.
