Best way to redistribute and rebalance portfolio
My question is how is the best way to redistribute and rebalance my portfolio? When I first started investing five years ago I had around 20 stocks with equal share. Now I currently have 5 stocks which make up nearly 80% of my portfolio. I am scared to sell my winners as I don't want to lose out on more gains, but at the same time I am frightening when one of these stocks moves down quickly (such as EBAY or SYMC recently). I want to make money please tell me how is that possible. How the decision has to be taken.
