I have a few multi bagger stocks in my portfolio, Should i continue to hold because i don't need the $$ now or cash them out? I have a long runway so i do not need the profits, what should i do?

Take out the capital and let the rest of your profits run

Consider it as part of your long term assets. If you're are not in need of any money, leave it and monitor your stocks performance against potential downside and make the decision to sell partially to mitigate losses. Ideally if the stocks are doing well and gives dividend, reinvest and let it grow.

If you don't need the money, why should you sell?

Good question
