It's never wrong to take that kind of profit off the table. I also have an average position of around 31. I am convinced though that the next 5 years will be very strong for WAG and I don't have a better idea to invest the $$'s. I fully expect WAG to more than double revenues by 2018 while maintaining or improving margins. I constantly re-evaluate and would not hesitate to sell if prospects turn south. WAG represents about 10% of my long term investments and for now I'm comfortable with that. I complement you for having the vision to buy WAG at $30, presumably during the ESRX disconnect, when most were doom and gloom. Good Luck.
