I'm glad you mentioned that.......When I buy stocks (most of the time they go down immediately) Ha Ha ...but after awhile when they finally get to a point......where I can sell half and get my investment back, I sell half and hold the remainder (which are basically free stock) and sell them when I get a nice return.........either double, triple or just when I no longer want to hold the stock I then sell the balance of my shares....seems to work for me. But I do like your 20% idea too......bill in Evans Ga
