Portfolio Performance Evaluation in Alternative Investment Fund Managers
Portfolio performance evaluation is a critical component in the Alternative Investment Fund Managers (AIFM) industry, helping investors make informed decisions about their investments. Evaluating the performance of a portfolio involves analyzing various performance metrics and ratios that provide insights into the risk-adjusted returns and overall effectiveness of a portfolio manager. This article will explore the key performance measurement ratios and metrics, their importance in portfolio management, and how they assist investors in selecting the best portfolio manager.
Performance Measurement Ratios and Metrics
In a way to choose the AIFM investors use several key ratios and metrics to evaluate portfolio performance. The table below outlines some of the most well-known and important ones:
|
Metric |
Description |
|
Sharpe Ratio |
Measures the risk-adjusted return of an investment. Calculated as (Portfolio Return - Risk-Free Rate) / Standard Deviation. Indicates how much excess return is received for the extra volatility endured. |
|
Treynor Ratio |
Measures returns earned in excess of that which could have been earned on a risk-free investment per unit of market risk. Calculated as (Portfolio Return - Risk-Free Rate) / Beta. |
|
Sortino Ratio |
Similar to the Sharpe Ratio but uses downside deviation instead of standard deviation, focusing on harmful volatility. |
|
Information Ratio |
Measures portfolio returns above the returns of a benchmark, usually an index, relative to the volatility of those returns. Calculated as (Portfolio Return - Benchmark Return) / Tracking Error. |
|
M-squared |
Provides a risk-adjusted return comparison to a benchmark, scaling the Sharpe Ratio by the benchmark standard deviation. |
Combining these metrics provides a more comprehensive view of portfolio performance:
- Sharpe Ratio indicates overall risk-adjusted return.
- Treynor Ratio focuses on market risk specifically, which is important for diversified portfolios.
- Sortino Ratio better addresses the concerns of investors who are particularly averse to downside risk.
- Information Ratio measures the ability of the manager to generate excess returns relative to a benchmark.
- M-squared offers a clear risk-adjusted performance measure in comparison to a benchmark.
Evaluating these metrics together helps investors understand not just the return, but the nature and quality of the risk taken to achieve those returns.
To illustrate, consider the attribution results for a hypothetical portfolio. The portfolio invests in liquid instruments: stocks, bonds, and money market securities. An attribution analysis appears below is a table presenting performance metrics for 4 hypothetical European Investment Funds for the year 2024:

Analysis and Selection of the Best Fund
Based on the metrics, Fund C appears to be the best option. It has the highest Sharpe Ratio (1.3), indicating excellent risk-adjusted returns. Its Treynor Ratio (0.9) and Sortino Ratio (1.6) are also the highest, suggesting it handles both market risk and downside risk effectively. Additionally, the Information Ratio (0.8) and M-squared (8.5%) indicate strong performance relative to the benchmark and overall risk-adjusted performance, respectively.
Understanding the Bogey
A "bogey" is a benchmark or standard against which the performance of a portfolio is measured. It is crucial in performance evaluation because it provides a reference point for assessing whether the portfolio manager has added value through active management. The bogey is designed to measure the returns the portfolio manager would earn if he or she were to follow a completely passive strategy.
Incorporating the bogey into overall performance evaluation helps determine if the returns achieved are due to skillful management or simply market movements. Investors can use the bogey to:
- Compare Performance: Evaluate if the portfolio has outperformed the market or specific benchmark.
- Assess Skill: Determine if the manager's strategies are effective compared to a passive investment strategy.
- Risk Management: Understand the risk taken to achieve returns compared to the benchmark.
Conclusion
Effective portfolio performance evaluation requires a comprehensive approach, utilizing a combination of performance ratios and metrics. These tools help investors discern the quality of returns in relation to the risks undertaken and the benchmarks set. In our analysis of European Investment Funds, Fund C stood out as the best performer based on these metrics. Understanding and using the concept of a bogey further aids investors in making well-informed decisions, ensuring that they choose portfolio managers who not only deliver high returns but do so efficiently and with skillful risk management.
