Answer: be based on multiple sources of risk.

## Explanation **Correct Answer: A** A successful portfolio risk budget will most likely be based on multiple sources of risk. ### Why Option A is Correct: 1. **Comprehensive Risk Management**: A risk budget should consider various risk sources including market risk, credit risk, liquidity risk, operational risk, and specific risk factors relevant to the portfolio. 2. **Diversification Benefits**: By considering multiple risk sources, the portfolio can be better diversified across different risk dimensions. 3. **Holistic Approach**: Modern portfolio theory emphasizes that risk budgeting should account for correlations and interactions between different risk factors, not just a single measure of risk. 4. **Practical Implementation**: In practice, successful risk budgeting involves decomposing total portfolio risk into contributions from various asset classes, strategies, and risk factors. ### Why Option B is Incorrect: - Risk budgeting is primarily about risk management and allocation, not about guaranteeing superior performance compared to passive investing. - Passive investing can be part of a risk-budgeted portfolio, and risk budgeting doesn't inherently promise outperformance. - Performance depends on many factors beyond just risk budgeting. ### Why Option C is Incorrect: - While risk budgeting considers risk-adjusted returns, it doesn't necessarily lead to investing only in assets with the highest return per unit of risk. - Risk budgeting is about allocating risk across the portfolio according to investment objectives and constraints, not just maximizing Sharpe ratios. - It involves trade-offs between different risk factors and may include assets with varying risk-return profiles to achieve diversification. ### Key Concepts: - **Risk Budgeting**: The process of allocating a portfolio's total risk to different components (asset classes, strategies, managers) based on investment objectives. - **Multiple Risk Sources**: Includes systematic risk, idiosyncratic risk, factor risks, currency risk, etc. - **Risk Parity**: An approach that allocates risk equally across portfolio components rather than allocating capital equally. **Note**: The question asks what a successful portfolio risk budget will "most likely" do, making Option A the most accurate description of effective risk budgeting practices.
