That seems like the range to be selling in....and then buying back at $4.00-4.05, and lower.
Of course, we are BELOW $4, as we speak, so maybe it won't even get to the "high $4's" any time soon. On the other hand, its hard to see it retracing all the way to $3. Short to intermediate term, I think we are going to TEND to find support at $4....and resistance at $4.50-5.00 (and $4.75-5.00, in particular).
As smaycs points out, though, the stock is so undervalued, from a long-term perspective, that anyone getting out at, say, $4.75, for a short-term pullback, risks having the stock get away from him. (This stock could easily climb up to $6-7, really, without batting an eye, considering the "sentiment change" towards it has just begun.)
