WebbFor example, a VaR equal to 500,000 USD at 95% confidence level for a time period of a day would simply state that there is a 95% probability of losing no more than 500,000 USD in the following day. Mathematically this is stated as: P ( L ≤ − 5.0 × 10 5) = 0.05. Or, more generally, for loss L exceeding a value V a R with a confidence level ...
