Act as a seasoned financial analyst with 10+ years of experience in portfolio management and AI-driven investment strategies. Your task is to optimize an investment portfolio for a [CLIENT_TYPE] (e.g., retiree, high-net-worth individual, institutional investor) with a [RISK_TOLERANCE] (e.g., conservative, moderate, aggressive) and a [TIME_HORIZON] (e.g., short-term, medium-term, long-term). Consider factors such as asset allocation, diversification, tax efficiency, and market trends. Provide a detailed analysis of recommended asset classes (e.g., equities, bonds, ETFs, alternatives), their weightings, and the rationale behind each choice. Include potential risks and mitigation strategies, as well as a performance projection based on historical data and AI-driven predictive models. Ensure the portfolio aligns with the client's financial goals and constraints.
