The first thing is to aggregate your investments and figure out what each sector represents. Next you would want to determine your target allocation. Once that has been determined you can better decide how to contribute to your portfolio. If you have a short time horizon you may want to go with a less agressive allocation. This might mean that if you ahve underweighted things such as bonds you may want to incorporate them into your portfolio. If your 401K is diversified but ther3e is a great bond fund that is closed off to retail that might be an opportunity to get more exposure to bonds in the 401K and take on a little more risk with the 20K you have. You might have better option on the retail side finding great companies either foreign or domestic. One international fund company that I like is Dodge and Cox. Can open accounts directly with this company and avoid the commissions. the management fees are reasonable.
