正如我们之前所说,我们预计 delta-normal 方法会高估风险。回测时,只有 14 倍的收益率低于 VaR 低于 95% 显着性水平 (<16)。另一方面,在这种特殊情况下,GARCH 方法(23 个例外)似乎是一种有效的预测工具。 参考 Angelidis T., Benos A. and Degiannakis S. (December 2003) . The Use of GARCH Models i...
Value at risk (VaR) is one of the most widely used models in risk management. It is based on probability and statistics. VaR can be characterized as a maximum expected loss, given some time horizon and within a given confidence interval. Its utility is in providing a measure of risk that...

Under the Monte Carlo method, Value at Risk is calculated by randomly creating a number of scenarios for future rates using non-linear pricing models to estimate the change in value for each scenario, and then calculating the VaR according to the worst losses. ...

aValue at risk (VaR) is the most widely used risk management model. However, in extreme situations, VaR models do not function very well. That is why these models have been supplemented with “scenario” or “stress” testing. But this approach may not be adequate to control risks. An ob...
