B) Bootstrapping can be used to compute both value at risk (VaR) and expected shortfall (ES).
C) Bootstrapping does not require a variance-covariance matrix.
D) Bootstrapping generates multiple samples.
答案:D
解析:In regard to (A), (B) and (C), each are true of both HS and bootstrapped HS (so they are not differences). But while historical simulation computes based on the single sample, bootstrapping generates multiple samples where each sample is drawn with replacement from the original historical data.
