Haha!
IMO - it is critical to success to cut 'em quickly when things don't go as I anticipate. Now there are times when I will hold a stock that may look to be turning south but as long as I entered the trade anticipating that it could happen, I can stick with it. For me, when things happen that I have not anticipated happening then I head for the hills. Maybe it sounds weird, but if a stock goes up way to fast I also exit! MCP was a recent example - thought it would eventually hit $75 but when it did it in days instead of the months I had anticipated - I RAN!!! Now, several weeks later, after topping out at $79 it is down to $59 now.
I HATE to lose money!
But I hate to lose BIG money even more!!
