Introduction

Investment Analysis and Portfolio Management is a fundamental subject in finance that involves evaluating securities, constructing portfolios, and managing investment risks. The problems from chapters 21, 23, and 24 of the prescribed textbook require detailed calculations and analyses to understand different investment concepts and strategies. This paper aims to provide comprehensive solutions to the specified problems, emphasizing the use of Excel for calculations, transparency in methodology, and clarity in interpretation.

Chapter 21: Investment Portfolio Optimization and Risk Management

The problems in Chapter 21 focus on portfolio selection, risk-return trade-offs, and the application of modern portfolio theory.

Problem 2 (p. 885)

This problem involves calculating the optimal risky portfolio using data on expected returns, variances, and covariances of different assets. The solution begins with collecting the relevant data, arranging it in Excel, and applying matrix algebra to compute the efficient frontier.

Using Excel, the first step is to input the expected returns, variances, and covariance matrix of the assets:

- Expected returns: Asset A = 12%, Asset B = 8%

- Variances and covariances are derived from historical data.

Next, the calculations involve determining the weights of assets that maximize the Sharpe ratio or minimize portfolio variance. Formulas involve:

- Portfolio expected return: \(E(R_p) = w_A E(R_A) + w_B E(R_B)\)

- Portfolio variance: \(\sigma_p^2 = w_A^2 \sigma_A^2 + w_B^2 \sigma_B^2 + 2w_A w_B \text{Cov}(A,B)\)

Excel functions such as 'MMULT,' 'MINVERSE,' and Solver are employed to find the optimal weights that satisfy the investment criteria. The detailed Excel steps include setting up the covariance matrix, using Solver to minimize portfolio variance for a given return, and plotting the efficient frontier.

Problem 8 (p. 887)

This problem focuses on calculating Value at Risk (VaR) for a portfolio using historical data and analyzing how different confidence levels affect risk assessment.

The process involves:

- Calculating the portfolio's mean return and standard deviation based on historical data.

- Using Excel to simulate potential losses, applying the historical simulation method.

- Computing VaR at specified confidence levels (e.g., 95%, 99%) by finding the loss percentile corresponding to these probabilities.

The Excel approach includes organizing the historical returns, calculating the portfolio's returns, sorting the data, and identifying the percentile corresponding to the selected confidence levels. The results provide insight into potential downside risks for the portfolio.

Chapter 23: Portfolio Performance Evaluation

Problem 2 (p. 985) involves calculating the measures of portfolio performance, including the Sharpe ratio, Treynor ratio, and Jensen's alpha.

Using Excel, the steps are:

- Input the portfolio's actual return, risk-free rate, and benchmark return.

- Calculate excess returns and the portfolio's beta with respect to the market.

- Compute the performance metrics:

- Sharpe ratio = \(\frac{E(R_p) - R_f}{\sigma_p}\)

- Treynor ratio = \(\frac{E(R_p) - R_f}{\beta_p}\)

- Jensen's alpha = \(E(R_p) - \left[ R_f + \beta_p \times (E(R_m) - R_f) \right]\)

The analysis compares these ratios to determine the portfolio's risk-adjusted performance relative to benchmarks.

Chapter 24: Active Portfolio Management and Performance Attribution

Problem 4 (p. 1037) requires analyzing active vs. passive management performance by decomposing active returns and evaluating skill.

The steps involve:

- Calculating the portfolio's excess return over the benchmark.

- Attributing performance to allocation decisions and security selection.

- Using regression analysis in Excel to determine the alpha and beta of the active portfolio.

- Interpreting the results to assess managerial skill.

The detailed Excel setup includes inputting returns data, running regressions, and analyzing residuals to measure the value added by active management.

Conclusion

The solutions to these problems demonstrate the application of quantitative methods in investment analysis, highlighting the importance of Excel in performing complex calculations. Accurate assessment of portfolio risk, return, and performance metrics is crucial for making informed investment decisions. Mastery of these concepts enhances portfolio construction and risk management, vital skills for investors and financial analysts.
