I am writing this article because after 14+ years of investing, for the first time I feel like i'm in a FIFO crowd (explained below). I bought in to Facebook at $19 and rode it out to $70+ today. This is my exit before the herd also leaves. Am I leaving early, very likely. Am I going to be annoyed when Facebook hits $90, probably. But being able to dictate to the market my belief and be able to walk away is an amazing feeling and having a 3.5 bagger (350% return) is not a bad time to walk away.
