Portfolio Performance Evaluation

Why is Portfolio Performance Evaluation Important?
Portfolio performance evaluation is a crucial aspect of investment management as it allows investors and portfolio managers to assess the effectiveness of their investment strategies, identify areas for improvement, and make informed decisions about future investments. By regularly evaluating portfolio performance, investors can ensure that their investments are aligned with their goals and risk tolerance.

What is Portfolio Performance Evaluation?
Portfolio performance evaluation is the process of measuring and analyzing the returns and risk of a portfolio over a specific period. This process involves comparing the portfolio's performance to relevant benchmarks, such as market indices or peer groups, and assessing the portfolio's risk-adjusted returns. Performance evaluation also takes into account factors such as asset allocation, security selection, and timing of investments.

How does Portfolio Performance Evaluation Work?
The process of portfolio performance evaluation typically involves the following steps:
1. Collecting and organizing portfolio data, including returns, holdings, and transactions
2. Selecting appropriate benchmarks for comparison
3. Calculating performance metrics, such as total return, risk-adjusted return, and attribution analysis
4. Interpreting the results and identifying areas for improvement

CFA Level 3 - Portfolio Performance Evaluation Example Questions

Test your knowledge of Portfolio Performance Evaluation

Question 1

John, a portfolio manager, is evaluating the performance of three portfolios over the past year. Portfolio A had a return of 10% with a standard deviation of 8% and a beta of 0.9, Portfolio B had a return of 12% with a standard deviation of 12% and a beta of 1.1, and Portfolio C had a return of 9% with a standard deviation of 6% and a beta of 0.7. The risk-free rate during this period was 2%, and the market return was 11% with a standard deviation of 10%. John wants to rank the portfolios based on their risk-adjusted performance using the Treynor ratio. Which portfolio had the highest Treynor ratio?

Portfolio B had the highest Treynor ratio. Although it had the highest return, its higher standard deviation and beta indicate that it took on more risk to achieve those returns, which may not necessarily translate to the best risk-adjusted performance when only systematic risk is considered. Portfolio A had the highest Treynor ratio. While Portfolio A had a moderate return and risk level, its performance was not as impressive as Portfolio C's when considering the excess return earned per unit of systematic risk. The Treynor ratio focuses on beta, and Portfolio C's lower beta gave it an advantage. Portfolio C had the highest Treynor ratio. The Treynor ratio measures excess return per unit of systematic risk (beta). Portfolio C's lower beta and relatively high return resulted in a higher risk-adjusted performance compared to Portfolios A and B when systematic risk is considered.

Correct Answer: Portfolio C had the highest Treynor ratio. The Treynor ratio measures excess return per unit of systematic risk (beta). Portfolio C's lower beta and relatively high return resulted in a higher risk-adjusted performance compared to Portfolios A and B when systematic risk is considered.

To determine which portfolio had the highest Treynor ratio, we need to calculate the ratio for each portfolio and compare them. The Treynor ratio is calculated as (Portfolio Return - Risk-Free Rate) / Portfolio Beta. Portfolio A: (10% - 2%) / 0.9 = 8.89% Portfolio B: (12% - 2%) / 1.1 = 9.09% Portfolio C: (9% - 2%) / 0.7 = 10% Portfolio C has the highest Treynor ratio at 10%, indicating that it provided the highest excess return per unit of systematic risk (beta). Portfolio A had a lower Treynor ratio than Portfolio C, despite having a higher absolute return, because its beta was higher, meaning it took on more systematic risk to achieve those returns. Portfolio B had the highest absolute return but also the highest beta, resulting in a Treynor ratio lower than Portfolio C's. The high return was offset by the high systematic risk taken.

Question 2

Samuel is a portfolio manager at a large investment firm. He manages two equity portfolios: Portfolio A and Portfolio B. Over the past three years, the portfolios have performed as follows: Portfolio A: Annualized return of 12%, standard deviation of 10%, beta of 1.1, tracking error of 2% Portfolio B: Annualized return of 14%, standard deviation of 13%, beta of 1.3, tracking error of 3% The risk-free rate during this period was 2%, and the market return was 10% with a standard deviation of 12%. The benchmark index for both portfolios had an annualized return of 11%. Samuel wants to evaluate the risk-adjusted performance of each portfolio using the Sharpe ratio, Treynor ratio, Information ratio, and M-squared measure. After calculating these measures, which portfolio's performance was the most impressive based on the M-squared measure?

To determine which portfolio had the better risk-adjusted performance based on the M-squared measure, Samuel first calculates the Sharpe ratio of each portfolio: Portfolio A: Sharpe ratio = (12% - 2%) / 10% = 1.0 Portfolio B: Sharpe ratio = (14% - 2%) / 13% = 0.92 He then calculates the M-squared measure using the Sharpe ratio of the portfolio and the standard deviation of the market: Portfolio A: M-squared = 2% + 1.0 * 12% = 14% Portfolio B: M-squared = 2% + 0.92 * 12% = 13.04% Based on the M-squared measure, Portfolio A had the better risk-adjusted performance, as it has a higher M-squared value of 14% compared to Portfolio B's 13.04%. To determine which portfolio had the better risk-adjusted performance based on the M-squared measure, Samuel first calculates the Treynor ratio of each portfolio: Portfolio A: Treynor ratio = (12% - 2%) / 1.1 = 9.09% Portfolio B: Treynor ratio = (14% - 2%) / 1.3 = 9.23% He then calculates the M-squared measure using the Treynor ratio of the portfolio and the beta of the market (which is 1): Portfolio A: M-squared = 2% + 9.09% * 1 = 11.09% Portfolio B: M-squared = 2% + 9.23% * 1 = 11.23% Based on the M-squared measure, Portfolio B had the better risk-adjusted performance, as it has a slightly higher M-squared value of 11.23% compared to Portfolio A's 11.09%. However, the difference is minimal and both portfolios have similar risk-adjusted performance. To determine which portfolio had the better risk-adjusted performance based on the M-squared measure, Samuel first calculates the Sharpe ratio of the market, which is (10% - 2%) / 12% = 0.67. He then calculates the M-squared measure for each portfolio: Portfolio A: M-squared = 2% + 0.67 * 10% = 8.7% Portfolio B: M-squared = 2% + 0.67 * 13% = 10.71% Based on the M-squared measure, Portfolio B had the better risk-adjusted performance, as it has a higher M-squared value of 10.71% compared to Portfolio A's 8.7%.

Correct Answer: To determine which portfolio had the better risk-adjusted performance based on the M-squared measure, Samuel first calculates the Sharpe ratio of the market, which is (10% - 2%) / 12% = 0.67. He then calculates the M-squared measure for each portfolio: Portfolio A: M-squared = 2% + 0.67 * 10% = 8.7% Portfolio B: M-squared = 2% + 0.67 * 13% = 10.71% Based on the M-squared measure, Portfolio B had the better risk-adjusted performance, as it has a higher M-squared value of 10.71% compared to Portfolio A's 8.7%.

To determine which portfolio had the better risk-adjusted performance based on the M-squared measure, we first need to calculate the Sharpe ratio of the market: Sharpe ratio (market) = (Market return - Risk-free rate) / Standard deviation of market = (10% - 2%) / 12% = 0.67 Next, we calculate the M-squared measure for each portfolio using the market Sharpe ratio and the portfolio's standard deviation: Portfolio A: M-squared = Risk-free rate + Sharpe ratio (market) * Standard deviation (Portfolio A) = 2% + 0.67 * 10% = 8.7% Portfolio B: M-squared = Risk-free rate + Sharpe ratio (market) * Standard deviation (Portfolio B) = 2% + 0.67 * 13% = 10.71% Based on the M-squared measure, Portfolio B had the better risk-adjusted performance, as it has a higher M-squared value of 10.71% compared to Portfolio A's 8.7%. The other answers are incorrect because they either use the wrong formula for calculating the M-squared measure or use the portfolio's Sharpe ratio or Treynor ratio instead of the market's Sharpe ratio.

Question 3

Amanda is a portfolio manager at a large investment firm. She is responsible for managing three equity portfolios: Portfolio A, Portfolio B, and Portfolio C. Over the past year, the portfolios have performed as follows: Portfolio A: Return of 14%, standard deviation of 10%, beta of 1.1 Portfolio B: Return of 16%, standard deviation of 13%, beta of 1.3 Portfolio C: Return of 12%, standard deviation of 8%, beta of 0.9 The risk-free rate during this period was 2%, and the market return was 13% with a standard deviation of 11%. Amanda wants to evaluate the risk-adjusted performance of each portfolio using the Sharpe ratio, Treynor ratio, and the Information ratio. The benchmark index for the Information ratio had a return of 12% over the same period. After calculating these measures, which portfolio's performance was the most impressive based on the Information ratio?

Portfolio B had the most impressive performance based on the Information ratio. The Information ratio measures the risk-adjusted return of a portfolio relative to a benchmark index. It is calculated by dividing the portfolio's excess return over the benchmark by the tracking error. Although Portfolio B had a higher return than Portfolio A, its higher standard deviation resulted in a lower Information ratio compared to Portfolio A. Portfolio C had the most impressive performance based on the Information ratio. The Information ratio measures the risk-adjusted return of a portfolio relative to a benchmark index. It is calculated by dividing the portfolio's excess return over the benchmark by the tracking error. Despite Portfolio C having the lowest standard deviation among the three portfolios, its return of 12% was equal to the benchmark return, resulting in an Information ratio of zero, which is less impressive than the positive Information ratios of Portfolios A and B. Portfolio A had the most impressive performance based on the Information ratio. The Information ratio measures the risk-adjusted return of a portfolio relative to a benchmark index. It is calculated by dividing the portfolio's excess return over the benchmark by the tracking error. Portfolio A's return of 14% exceeded the benchmark return of 12% by 2 percentage points, while having a lower standard deviation than Portfolio B, resulting in a higher Information ratio compared to the other portfolios.

Correct Answer: Portfolio A had the most impressive performance based on the Information ratio. The Information ratio measures the risk-adjusted return of a portfolio relative to a benchmark index. It is calculated by dividing the portfolio's excess return over the benchmark by the tracking error. Portfolio A's return of 14% exceeded the benchmark return of 12% by 2 percentage points, while having a lower standard deviation than Portfolio B, resulting in a higher Information ratio compared to the other portfolios.

The Information ratio measures the risk-adjusted return of a portfolio relative to a benchmark index. It is calculated by dividing the portfolio's excess return over the benchmark by the tracking error. Portfolio A had a return of 14%, which exceeded the benchmark return of 12% by 2 percentage points. Portfolio B had a higher return of 16%, but also a higher standard deviation of 13% compared to Portfolio A's 10%. Portfolio C's return of 12% was equal to the benchmark return. Although Portfolio B had the highest absolute return, Portfolio A's excess return over the benchmark, combined with its lower standard deviation, results in a higher Information ratio, making it the most impressive performance based on this measure. Portfolio C's Information ratio would be zero since its return matched the benchmark, making it less impressive than the positive Information ratios of Portfolios A and B.
