Introduction to AS Portfolio Optimization v. 1.1
AS Portfolio Optimization v. 1.1 is designed to assist users in creating and managing portfolios of securities, leveraging the principles of modern portfolio theory. This version emphasizes constrained optimization for minimum variance and tangent portfolios, providing tools to analyze and visualize the risk-return trade-off in investment portfolios. It operates with a default assumption of a zero risk-free rate for the estimation of the tangent portfolio, which can be adjusted based on user input. A key feature includes the ability to calculate and plot the efficient frontier, representing the set of portfolios offering the highest expected return for a given level of risk. This tool is particularly useful for financial analysts and portfolio managers who aim to optimize portfolio allocation to achieve specific investment objectives. For example, it can analyze time series data in Excel or CSV formats, calculate expected returns, variances, and covariances of assets, and simulate numerous portfolio compositions to identify those that lie on the efficient frontier.

Main Functions of AS Portfolio Optimization v. 1.1
Efficient Frontier Calculation and Visualization
ExampleGiven historical price data of several assets, AS Portfolio Optimization v. 1.1 can compute the expected returns, variances, and covariances, and then generate a set of random portfolios to plot the efficient frontier. This visualization helps in identifying the most efficient portfolios that offer the best risk-return trade-off.
ScenarioA portfolio manager looking to rebalance their portfolio would use this feature to evaluate different asset allocations and select an optimal mix that aligns with their risk tolerance and investment objectives.
Minimum Variance and Tangent Portfolio Optimization
ExampleBy optimizing the weights of different securities in a portfolio, AS Portfolio Optimization v. 1.1 identifies the minimum variance portfolio, which has the lowest possible risk for a given return, and the tangent portfolio, which offers the highest Sharpe ratio assuming a risk-free rate of zero.
ScenarioAn investment analyst can use this function to construct a new fund that aims to minimize risk while achieving a desired rate of return, or to find the most efficient portfolio that can be formed on the capital market line.
Custom Risk-Free Rate Adjustment
ExampleWhile the default risk-free rate is set to zero, users have the flexibility to input their own risk-free rate based on current market conditions or their investment policy, allowing for more accurate tangent portfolio calculations.
ScenarioIn a low-interest-rate environment, a pension fund manager may adjust the risk-free rate to reflect the yield on government securities, helping to tailor the portfolio to meet the fund's long-term liabilities.
