That is a tough question and to be honest with you, I sold 1/2 my shares today just to be safe, I normally take some profits on the way up in almost all stocks i trade, I almost always take my risk down when possible.
Okay, sorry, back to your question, if they have a follow up PR, I like our chances, if MOMO slows and no follow up, not sure I will like it, but sure going to find out, but even if it drops a little, I believe it will run again and most likely more than once from what the birdies chirpped "-)
I have always held a few shares in FOFU, but when the MOMO train comes thru, i always get many more.
