The lack of volume is the only thing that indicates that this is mere manipulation. I cannot tell you what to do other than to say that I personally will hold the position. LNKD moved today on less than half the usual volume and is up 10% since the announcement of the FB jobs board which makes no sense.
Eventually something will give and this will fall. Hard.
As to how much I am down. More than enough on this trade. (care to trade positions??? ;-) )
These last two weeks have been rough on me. Some weeks I can do no wrong and some weeks I can do no right :-)
