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.

Hedging Using CVaR Portfolio Optimization

This example shows how to model two hedging strategies using CVaR portfolio optimization with a PortfolioCVaR object.
