RE: S/PI hardly think that 1 week of fluctuating around 3 dollars can be considered becoming "fully valued". A 90% growth spurt in under a month is pretty exceptional growth for any stock, and I wouldn't be the least bit surprised it hovers here even longer.
After that kind of growth, one would normally expect a serious pullback, yet after the two recent price surges, profit takers have barely been able to budge the price. There are still a lot more people willing to buy than are willing to sell, and I wouldn't be surprised if we were up around 3.60 by late August.
