Unless you want to invest in the market yourself, just go to Money or a financial site like that, and do a portfolio manager, it will tell you where/how to invest in mutual funds. At under 30, I'd be in almost all stocks, mostly high risk, aggressive growth. Just make sure you choose a fund with low fees, 0.5% or less is what i look for. I mostly pick stocks that are beaten down, but solid choices. I bought Home Depot at 33-35 and sold it at 41 this morning. Best Buy is another I own that is recently in a funk.
