Generally speaking long term investing is the way to go. But along the way some stocks are going to perform badly. To wit, the Borussia Dortmund GmbH & Co. Kommanditgesellschaft auf Aktien (ETR:BVB) share price managed to fall 58% over five long years. That is extremely sub-optimal, to say the least. Shareholders have had an even rougher run lately, with the share price down 17% in the last 90 days.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.
