A high-net-worth client with a long investment horizon and high risk tolerance approaches their portfolio manager seeking to maximize return for a given level of risk. The portfolio manager decides to construct a portfolio that lies on the efficient frontier. Which of the following best describes the core principle being applied?

Question: A high-net-worth client with a long investment horizon and high risk tolerance approaches their portfolio manager seeking to maximize return for a given level of risk. The portfolio manager decides to construct a portfolio that lies on the efficient frontier. Which of the following best describes the core principle being applied?

Answer options: ✅ Each portfolio on the efficient frontier offers the highest possible expected return for its given level of risk.

• The efficient frontier represents the set of portfolios with the lowest possible risk for any given expected return.
• Portfolios below the efficient frontier are preferred as they offer higher returns with lower risk.
• The efficient frontier primarily minimizes the impact of unsystematic risk on portfolio returns.

Correct answer: Each portfolio on the efficient frontier offers the highest possible expected return for its given level of risk.

Explanation: The efficient frontier comprises portfolios that offer the maximum expected return for a given level of risk or the minimum risk for a given expected return. This principle guides optimal portfolio construction under Modern Portfolio Theory.
