备考FRM考试，关于VAR的例题解析！

在备考FRM考试中，VAR（风险价值模型）是需要考生所掌握的。VAR在市场正常波动下，某一金融资产或证券的zui大可能损失。关于VAR的例题解析如下文所示！

Consider the delta-normal and full-revaluation approaches to estimating the VAR of non-linear derivative instruments. Which of the following is NOT a requirement for either the delta-normal or full-revaluation approach？

A. The VAR(1%) of the underlying asset is adjusted by a factor reflecting the price sensitivity of the derivative price to changes in the underlying asset price.

B. A second order adjustment is made to the underlying asset VAR(1%) to account for the non-linear relationship between the derivative and the underlying asset.

C. The VAR(1%) of the derivative is calculated by revaluing the derivative at the price corresponding to a VAR(1%) decline in the value of the underlying asset.

D. The VAR(1%) of the asset underlying the derivative is based on an assumed normal distribution.

Answer:D

The delta-normal approach to estimating the VAR of a non-linear derivative adjusts the VAR of the underlying asset for the delta (slope) and gamma (curvature) of the relationship between the derivative and the underlying. The VAR of the underlying asset can be calculated using parametric methods (assuming a normal distribution) or using historical methods (which does not assume a normal distribution).
