This question already has an answer here:
I started investing in the stock market last year. I've read tons of information and tried different products.
My knowledge about compound interest is, when you invest in one stock, get 5% return, you use this 5% to buy more stocks and then make interest based on your new stack of stocks.
There are ETFs and robo advisers which will automatically do this for you.
But, I have my stocks on my broker (around 7 companies at the moment). I have currently a 8% gain.
How do I sell/buy to "compound" my interest?
Do i sell one company completely and buy a new one? Do I sell 8% worth of stocks and buy more of one or more companies?
