Stock ran up on last earnings suprise, my guess is there's fear that the earnings due out in a week won't be as good - if they aren't it won't be pretty. ADBE should be good place to be, but they have recent history of leaking bad news to brokerage community without informing little investors at same time.
That is exactly what I fear. I own CREAF and it sroped 30% in two weeks without any news. APM started it silde long before the bad news is out. If ADBE asia sale only account for a small fraction of their income, then I susepct some big boy is selling because they know something that we do not.
