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 Webtail value at risk or tail conditional expectation. Tail value at risk is an economic cost of ruin (ECOR)-like measure in the sense that both the probability and the cost of "tail events" are considered; the calculation differs from ECOR in such a way that it has a desirable statistical property (i.e., coherence).
