I hate stop losses. I've have this stock since the 60's. Once in a while I take some profit. I read a great in depth article that said MA will be a 1000 a share in five years. This stock will never thud. It will go down a little here and there and then will pop up. It is a cash cow. Pat Dorsey said it was a buy on Bulls and Bears, said it couldn't miss. I own Visa since the IPO. Never Never Sell.
