Yeah, well, that DAX portion was an old position that i counted to the "european" portion of my portfolio and it matched quite nicely the rebalancing ammount so i liquidated all of it. My portfolio is now clean of it :) (eu is covered by the stoxx 600 index which is way more diversified as the 30 positions in the DAX).
The "its in the past" is a valid argument though, because thats the same for sunc cost fallacy. Thanks for the reminder.
Draghis announcement concerned the introduction of QE in europe, that is, central banks will buy bonds. This will probably rise stock prices and is one main cause (i think) the dax jumped. This is what i meant what may have been predictable; it is just not predictable when the jumoping is over.
