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.
The PortfolioCVaR object has a separate
that stores the rate of return of a riskless asset.
The difference between net and gross portfolio returns is transaction costs.
