Abstract

When we model returns using a GARCH process with normally distributed innovations, we have already taken into account the second stylized fact (see Chap. 13). The distribution of the random returns automatically has a leptokurtosis and larger losses occurring more frequently than under the assumption that the returns are normally distributed. If one is interested in the 95 %-VaR of liquid assets, this approach produces the most useful results.
