It appears to have broken out of a descending wedge, retested the wedge trendline and appears primed to pump. It's also sat nicely on top of the 100MA which should provide support.
For this reason, I'm long here with a tight stop at $3.90.
I have a crazy-high target of $49 based on the falling wedge breakout, but in reality would be looking to sell in stages on the way up.
