The Well-Constructed Portfolio

A well-constructed portfolio aims to provide investors with promised characteristics efficiently, without guaranteeing benchmark-like results. Key elements include:

• Clearly defined investment process and philosophy.
• Alignment with investor risk and structural expectations.
• Implementation of a risk-efficient methodology.
• Maintenance of low operating costs.

Differences among Funds

Since each investor is unique, every investment mandate must be tailored accordingly. Well-constructed portfolios may vary depending on their specific objectives and management. Here are accepted principles for portfolios with similar desired characteristics:

• Achieving similar risk levels with fewer positions often indicates effective risk management.
• Lower absolute volatility is generally preferred.
• A higher active share, which measures the deviation from the benchmark, is generally more desirable, showcasing the manager's alpha skill.
• Blending equity portfolios can enhance diversification by leveraging different managers' expertise in various factors.

Question

Assume you have two funds with almost identical risk exposures. Which of the following would likely be considered desirable?

1. Lower active share.
2. Higher active share.
3. More positions.

Solution

The correct answer is B.

Active share measures how different a manager's portfolio is from the benchmark. A higher active share suggests the manager is actively making bets, which is usually a positive sign of expertise.

Option C is not the best choice since having more positions can lead to higher transaction costs, tax inefficiencies, and less focused investing.
