Yea, i remember a time when I was that fool. Back when i was first trying to be a momentum player and i'd see news come across the wires about a stock up 10% and try to jump on only to realize that i got in at the top. I'd watch the stock drop for a few weeks and get discouraged then cut my losses to prevent more from occuring. Immediately following, the stock would rocket again and not stop until it gained at least 60-85% and i was on the sideline watching.
