本文为大家讲解FRM®二级:非参数法知识点的相关内容,下面一起来看Weighted Historical Simulation Approaches的相关计算。
all non-parametric approaches are based on the underlying assumption that the near future will be sufficiently like the recent past that we can use the data from the recent past to forecast risks over the near future
Volatility-weighted histroical simulation(HW:1998)
Update return information to take account of recent changes in volatility
Actual returns in any period t are therefore increased(or decreased),depending on whether the current forecast of volatility is greater(or less than)the estimated volatility for period t.
波动率越大,收益率越大
The volatility-weighted HS has a number of advantages relatives to the traditional equal-weighted and the age-weighted approaches:【点击免费下载>>>更多FRM学习相关资料】
Takes account of volatility changes in a natural and direct way.
考虑到了波动率的因素。
Eables us to incorporate information from GARCH forecasts into HS VaR and ES estimation.
结合GARCH模型对VaR/ES预测。
Allows us to obtain VaR and ES estimates that can exceed the maximum loss in our histroical data set.
VaR/ES的估计可以超过历史数据的最大损失。
Empirical evidence indicates that this approach produces superior VaR estimates to the BRW one.
研究发现此方法的VaR比Age-weighted估计得好。
