Examples and How To

Asset Returns and Moments of Asset Returns Using Portfolio Object

Mean-variance portfolio optimization problems require estimates for the mean and covariance of asset returns.

Working with a Riskless Asset

The Portfolio object uses a separate RiskFreeRate property that stores the rate of return of a riskless asset.

Working with Transaction Costs

The difference between net and gross portfolio returns is transaction costs.

Asset Allocation Case Study

This example shows how to set up a basic asset allocation problem that uses mean-variance portfolio optimization to estimate efficient portfolios.

Portfolio Optimization Examples

The following sequence of examples highlights features of the Portfolio object in the Financial Toolbox™.
