I dont know. It happened a good couple of times now that someone sold shares for 0.1btc. Ok, maybe he was frightened, but short after a good message in this thread?
...
maybe it is profitable for someone:
Low of the day in ASICMINER on GLBSE 0.00021

Someone's account got hacked or something ?
Yep
The largest beneficiary of my account compromise was for approx. 2400 shares of ASICMINER.
While this amount might have been purchased in coordination with the perpetrator for later sale I think it's unlikely.
There was a significant period of time between when the 2400 ask was placed and then purchased. This does not support the theory of profit taking related to a prior conspiracy.
