Conditional value at risk คือ
Web1. Conditional value at risk is a risk measure derived by taking a weighted average between the value at risk and losses exceeding the value at risk. The value at risk is a widely used in financial risk management to measure the potential loss in value of a risk y asset or portfolio over a defined period for a given confidence interval. Expected shortfall (ES) is a risk measure—a concept used in the field of financial risk measurement to evaluate the market risk or credit risk of a portfolio. The "expected shortfall at q% level" is the expected return on the portfolio in the worst of cases. ES is an alternative to value at risk that is more sensitive to the shape of the tail of the loss distribution. Expected shortfall is also called conditional value at risk (CVaR), average value at risk (AVaR), …
