I'll stick with my system.Look, research a bunch of ETFs and diversify them into your portfolio. At your age you dont want a risk portfolio anyway. OR just go to one of the big house names at Wells Fargo or Bank of America and have them manage it.
You want superior returns and capital protection....don't we all. Diversification at your age is your best bet. Anything else....then you open to risk.
Very simple; buy stuff that is going up and don't hold losers in the portfolio for more than a day.
