Examples and How To

Asset Returns and Scenarios Using PortfolioCVaR Object

Given a sample of scenarios, the conditional expectation that defines the sample CVaR of the portfolio is expressed as a finite sum, a weighted average of losses.

Working with a Riskless Asset

The PortfolioCVaR 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.

Concepts
