The stock was down instantly this morning, so it was hard for most to get out at the high. It sounds like everyone is playing the same game. Buy on rumor sell on news.
Furthermore, every investor has a different tolerance level especially if they would have bought in a few months back in the low $0.20s. The ones that bought over the last couple of days in the high $0.40's are feeling the pinch more.
With furthre NR pending, whose to say that it can't get back to where it was yesterday?
