A retest of its previous highs is a definite possibility. I usually scale into breakout plays with an initial entry of 1/2 overall risk allotment for this purpose. If it does retest, and holds, then I will add the remaining 1/2.
The news responsible for the move was by Piper Jaffray upgrade to outperform from market perform. It's less than four bucks away from it's all time high.
Thanx for the alert
