This document discusses three levels of diversification that can help reduce investment risk: 1) Diversifying across different asset classes, industries, company sizes, geographic regions, and investment philosophies. 2) Investing in mutual funds to access a wider range of investments than possible individually. 3) Strategic asset allocation, which weights conservative and growth assets to balance risk and potential returns based on goals and risk tolerance. Regular adjustments over time are recommended to align the portfolio with changing needs and goals. Diversification and asset allocation do not prevent losses but can help manage risk.
