Even the best stock pickers will make plenty of bad investments. And unfortunately for AIXTRON SE (ETR:AIXA) shareholders, the stock is a lot lower today than it was a year ago. The share price has slid 54% in that time. Even if you look out three years, the returns are still disappointing, with the share price down42% in that time. Furthermore, it's down 16% in about a quarter. That's not much fun for holders. This could be related to the recent financial results - you can catch up on the most recent data by reading our company report.

On a more encouraging note the company has added €48m to its market cap in just the last 7 days, so let's see if we can determine what's driven the one-year loss for shareholders.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Unhappily, AIXTRON had to report a 27% decline in EPS over the last year. The share price decline of 54% is actually more than the EPS drop. So it seems the market was too confident about the business, a year ago.

A Different Perspective

AIXTRON shareholders are down 54% 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. On the bright side, long term shareholders have made money, with a gain of 9% 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. 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.
