everyone has their own comfort level. i like to put in a stop loss at a level i can live with and then let it ride. i think we are just at the first stage up and if you sell now someone else will make a lot of money with your shares. multiple news is due and unless this is disappointing in some way i don't see the sp going down. can't tell you what to do but i am not even thinking exit strategy right now. to each his own.
