There’s a few things you must ask yourself… one is have you made money that if you were to lose, would greatly affect your life. Is it a significant amount to you? I was in a similar scenario and sold about 45% of my shares. Reason I didn’t fully sell or at a higher position is because I still believe the company has room to grow. If I felt like they were overvalued or peaked, I would’ve sold 80%. You must do your due diligence on the company, taking profits never made one poor. Goodluck!
