'''Value at risk''' (VaR) is a financial risk metric that estimates the maximum probable loss of a portfolio over a specified time horizon at a given confidence level. It is the canonical example of the [[ludic fallacy]] in practice: a metric that performs well in calm markets because calm markets resemble casinos, and fails catastrophically in crises because crises are not casino events. VaR models dominated pre-2008 risk management, creating the illusion that tail risk had been measured and contained. The [[model risk]] inherent in VaR is not that it miscalculates probabilities but that it treats the probability distribution as stable when the distribution itself is the variable. A more honest measure is [[expected shortfall]], which asks not ''how bad can things get at 95% confidence'' but ''how bad is the average loss beyond that threshold.''
