I have not been able to pull the trigger to sell a portion or all of a stock to cash out since I thought it was a more long term hold stock. But in hindsight, I knew I should have at least cashed out half and continued to follow when my portfolio was up 75% or so. I am a relatively new investor. It is all now back down to my original investment level and looking back, I should have sold and reinvested in new opps.
You need a system, not guessing. One of my books is a solid foundation.
