I'm 45 and been holding most of these stocks for over 20+ years now. I've been thinking over Buffet's famous quote, "Diversification may preserve wealth but concentration can build wealth." I don't need to take profits and wouldn't want to pay capital gains on them either. I just wanted to see what everyone thinks or your own strategy for your portfolio? I have the time and it's not difficult for me to monitor and reposition here and there but ultimately just wanted to see everyones' thoughts and opinion (I also have another brokerage portfolio that consists of another 15-20+ stocks + funds that I monitor too)
