Mostly b/c I would like to watch it go up but also if sold it may may trade over the buyout price for a bit so maybe I could make more money. The Monday morning after the Viibryd was approved before the market opened when I saw it was only trading at 23+ I bought more shares b/c I thought it would go higher. I am still sitting on those shares so am glad I bought them. I just wish I had woken up sooner.
