For many investors, the main point of stock picking is to generate higher returns than the overall market. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term Ctac N.V. (AMS:CTAC) shareholders, since the share price is down 23% in the last three years, falling well short of the market return of around 18%.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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 the three years that the share price fell, Ctac's earnings per share (EPS) dropped by 39% each year. This fall in the EPS is worse than the 8% compound annual share price fall. This suggests that the market retains some optimism around long term earnings stability, despite past EPS declines.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Ctac the TSR over the last 3 years was -16%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Ctac shareholders are down 11% for the year (even including dividends), but the market itself is up 18%. 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 5%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand Ctac better, we need to consider many other factors.
