This is a desirable property from the portfolio risk management perspective which is not present in VaR measure and has always been considered as one of the shortcomings in using VaR for risk measurement purposes. Expected Shortfall Definition. The Expected Shortfall (ES) or Conditional VaR (CVaR) is a statistic used to quantify the risk of a portfolio. Given a certain confidence level, this measure represents the expected loss when it is greater than the value of the VaR calculated with that confidence level. Given a certain confidence level, this measure represents the expected loss when it is greater than the value of the VaR calculated with that confidence level. Since percentage VaR and VaR only differ by the current value of the portfolio, the remainder of the chapter focuses on percentage VaR. First, VaR and expected shortfall may underestimate the risk of securities with fat-tailed properties and a high potential for large losses. The “standard” VaR is interpreted as the worst possible loss under normal conditions over a specified period for a given confidence level. T/F -> Value at Risk asks how bad can things get? that the loss is greater than or equal to the VaR. The Expected Shortfall (ES) or Conditional VaR (CVaR) is a statistic used to quantify the risk of a portfolio. Given a certain confidence level, this measure represents the expected loss when it is greater than the value of the VaR calculated with that confidence level. As such, it relationship towards VaR becomes more clear. Conditional Value at Risk (CVaR) - FinanceTrainingCourse.com Again, in English, the expected shortfall is the average of all losses greater than the loss at a \(VaR\) associated with probability \(\alpha\), and \(ES \geq VaR\). G-expected shortfall (G-ES), which is a new type of worst-case expected shortfall (ES), is defined as measuring risk under infinite distributions induced by volatility uncertainty. Obviously, Value at Risk or Expected Shortfall - Quantdare Introduction It is a well … 14 which of the following is true of a covariance - Course Hero The VaR of the combined position is therefore greater than the sum of the VaRs of the individual positions, so the VaR is not subadditive.
