I got out of a stock at around +76%. It hit my sell mark. However, I missed 300%+ doing this. I didn't think it would keep going up... but they had a couple good wins and participated in the post US election take off. I was happy with the 76%... but I Would've liked the 300%+ better.
Can't hammer the hindsight. If you made money... you made money. Take it and run.
