I understand that nervous feeling. After what, a year of struggle, it seems like "all of a sudden" we're up substantially - and because this has taken so long, we really don't have much support in terms of a consolidation period should the stock start to go down - although my feeling is that we are starting a sideways trend right now which may last for awhile - until we get closer to earnings or someone comes out with some real "news".
I myself have put in trailing stops that allow me to ride the stock up without selling, yet sell if the stock tanks more than a couple of percentage points for whatever reason. They're far enough down that market volatility won't trigger them prematurely, yet tight enough that I won't feel badly if they actually spring.
I know, I know, this seems contrarian, but I've got to sleep at night too.
By the way, I don't think anyone who's hung in there with HANS from before "the drop" could be called greedy; vindication of wisdom and courage isn't greed.
