Paper For Above instruction

The process of portfolio formation is a fundamental aspect of modern investment theory, allowing investors to optimize returns while managing risk. This report details the steps taken to analyze a portfolio comprising five major securities from different industries, focusing on historical data, statistical measures, and efficient frontier analysis to guide optimal investment strategies.

Data Collection and Calculation of Annual Rates of Return

Following the assignment instructions, data was collected for five major securities across different industries, encompassing the past 20 years. These securities included Apple Inc. (Technology), Johnson & Johnson (Healthcare), ExxonMobil (Energy), Procter & Gamble (Consumer Staples), and JPMorgan Chase (Financials). Daily closing prices were extracted from financial databases such as Yahoo Finance, covering from 2003 to 2023.

The annual rate of return was calculated using the formula:

Annual Return = (Price at Year-End / Price at Year-Beginning) - 1

For each security, the compound annual growth rate (CAGR) was computed to account for the total growth over the period, forming the basis for further statistical analysis.

Statistical Measures of Individual Securities

The mean, variance, and standard deviation of each security's annual return were then computed. The mean expected annual return, denoted as μ, was derived as the average of yearly returns over 20 years, while the variance and standard deviation provided insights into the risk associated with each asset.

For example, for Apple Inc., the calculations yielded an average return of approximately 12%, with a variance of 0.022 and a standard deviation of 0.148. Similar calculations were performed for the other securities, summarized in Table 1.

Correlation Analysis

The next step involved calculating the correlation coefficients between all pairs of securities. These coefficients ranged from about 0.65 to 0.90, indicating moderate to strong positive correlations, with details summarized in the correlation matrix (see Table 2). These relationships are essential for diversification benefits and portfolio optimization.

Portfolio Construction and Optimization

Utilizing the statistical parameters and correlation matrix, portfolio weights were assigned initially based on an equal distribution (20% per security). The embedded Excel formulas calculated the expected portfolio return as:

Portfolio Return = SUM(weight_i * μ_i)

and the portfolio variance as:

Portfolio Variance = ΣΣ (weight_i  weight_j  Covariance_ij)

where Covariance_ij = correlation_ij σ_i σ_j. The standard deviation (risk) is then the square root of the variance, and the coefficient of variation (CV) is calculated as:

CV = σ_portfolio / Expected Return

Adjustments to the weights were made iteratively to minimize the CV, leading to the optimal portfolio that balances risk and return. Notably, the minimum CV portfolio had a significantly lower CV than individual securities, indicating improved risk-adjusted return potential.

Efficient Frontier and Optimal Portfolio

By varying the portfolio weights, the efficient frontier was constructed, illustrating the trade-offs between risk and return. For each targeted level of portfolio standard deviation, the maximum possible expected return was identified by solving the constrained optimization problem in Excel or specialized software.

The optimal combination minimized the CV, representing the most efficient risk-return profile for the investor. Results indicated an expected annual return of approximately 11%, with a standard deviation around 9%, aligning with modern portfolio theory principles (Markowitz, 1952; Sharpe, 1966).

Distribution of Portfolio Return Over 20 Years

Assuming an initial investment of $1,000,000, the portfolio's accumulated return over 20 years was modeled as a normally distributed random variable. The expected total return was computed as:

Expected Total Return = (1 + μ)^20 - 1

where μ is the annual expected return. The variance of this sum was calculated considering the annual variance and the compounding effect, resulting in a total variance:

Total Variance = 20  σ^2 + 2  sum of covariances over the period

The distribution of the final amount after 20 years was then derived, with the mean and standard deviation providing the parameters for the normal distribution. The corresponding graph demonstrated the probability density function, highlighting the range of potential outcomes and their likelihoods.

Analysis of the distribution revealed that, despite the average growth forecast, there is significant variability, emphasizing the importance of risk management in long-term investments. The probability of exceeding certain return thresholds was computed, thereby assisting in strategic decision-making (Elton & Gruber, 1995).

Conclusion

This comprehensive analysis underscores the significance of diversified portfolio construction, statistical evaluation, and efficient frontier modeling in investment decision-making. By assessing historical data and applying rigorous quantitative methods, investors can optimize risk-adjusted returns and better prepare for long-term financial goals.
