Another term for actual returns. Ex-post translated from Latin means "after the fact". The use of historical returns has traditionally been the most common way to predict the probability of incurring a loss on any given day. Ex-post is the opposite of ex-ante, which means "before the event".


Companies may try to obtain ex-post data to forecast future earnings. Another common use for ex-post data is in studies such as value at risk (VaR), a probability study used to estimate the maximum amount of loss a portfolio could incur on any given day.
