Tail value at risk (TVaR), also known as tail conditional expectation (TCE) or conditional tail expectation (CTE), is a risk measure associated with the more general value at risk. It quantifies the expected value of the loss given that an event outside a given probability level has occurred. See more There are a number of related, but subtly different, formulations for TVaR in the literature. A common case in literature is to define TVaR and average value at risk as the same measure. Under some formulations, it is … See more Closed-form formulas exist for calculating TVaR when the payoff of a portfolio $${\displaystyle X}$$ or a corresponding loss See more WebJan 29, 2024 · Estimating value at risk and conditional tail expectation for extreme and aggregate risks.
