I think up to $7 is a real possibility following the company's earnings report which I believe is scheduled in mid-February though I'm not sure on that. This company has a history of bouncing after such reports on the premise of future growth more than the actual numbers themselves. If this stock can just get to $6, which barring market destruction is a real possibility, $6.50 should be easy with a pop to probably about $7.
This week could be a bit forshadowing, even though Friday was bad - it closed at 5, which it hasn't done in a while. If we can see 5.51+ on Friday - with all the technicals aside, it maybe slowly moving towards 7. Though I think 7.20-7.30 is the limit for the year till late 2012.
