10.
The hybrid approach for estimating VaR is the combination of a parametric and a nonparametric approach. It
specifically combines the historical simulation approach with:
a.
The delta normal approach.
b.
The exponentially weighted moving average approach.
c.
The multivariate density estimation approach.
d.
The generalized autoregressive conditional heteroskedasticity approach.
Correct Answer: b
Rationale:
The hybrid approach combines two approaches to estimating VaR, the historical simulation and the
exponential smoothing approach (i.e. an EWMA approach). Similar to a historical simulation approach, the hybrid
approach estimates the percentiles of the return directly, but it also uses exponentially declining weights on past
data similar to the exponentially weighted moving average approach.
