Despite shrinking by €51m in the past week, X-FAB Silicon Foundries (EPA:XFAB) shareholders are still up 108% over 5 years

X-FAB Silicon Foundries SE (EPA:XFAB) shareholders have seen the share price descend 20% over the month. But that scarcely detracts from the really solid long term returns generated by the company over five years. In fact, the share price is 108% higher today. To some, the recent pullback wouldn't be surprising after such a fast rise. Ultimately business performance will determine whether the stock price continues the positive long term trend. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 41% drop, in the last year.

In light of the stock dropping 8.6% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

A Different Perspective

X-FAB Silicon Foundries shareholders are down 41% for the year, but the market itself is up 0.4%. 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 16% per year over half a decade. 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.
