Before outlining portfolio management suggestions, I'm assuming ITA readers have a savings and investment plan in effect. For saving suggestions, search for "The Golden Rule of Investing" and related topics. There are a number of blog entries related to preparing for retirement, and the earlier one begins retirement planning the better.
After establishing a savings plan, write down your investment plan. One place to begin is with the Dashboard worksheet contained inside the TLH Spreadsheet. Develop a Strategic Asset Allocation (SAA) plan. Laying out a plan does not mean it is chiseled in granite. The idea is to begin with a plan and then continue to learn if changes are necessary.
