Examples and How To

Asset Returns and Scenarios Using PortfolioMAD Object

Compute the expectation for MAD with samples from the probability distribution of asset returns.

Working with a Riskless Asset

The PortfolioMAD object has 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.
