Portfolio Diversification Strategy for a Long-Term Investor

Develop a comprehensive investment strategy for a long-term investor with a moderate risk tolerance. The portfolio should consist of a mix of asset classes, including stocks, bonds, and real estate investment trusts (REITs). Consider the investor's age, income, and financial goals. Allocate a minimum of 40% to domestic equities, 30% to international equities, 15% to fixed income, and 15% to alternative investments. Ensure the portfolio is rebalanced quarterly to maintain the target asset allocation. Provide a detailed breakdown of the portfolio's components, including the stocks, bonds, and real estate investment trusts (REITs) selected, and the rationale behind the investment decisions.
