Fairly significant break below 23.96 must have triggered sell orders. The volume is light but this is still painful. The conference takes place Oct.30 to Nov. 4 in San Diego hopefully they will have some good data to present.
There are alot of profits in this stock and people are taking them into the end of the month. The presentation at a conference in San Diego is next week so hopefully we get a pop out of that. This is definately in a down trending channel so it could get more painful.
