The historical simulation approach is more likely to provide an accurate estimate of the VaR than the Risk Metrics approach for a portfolio that consists of:
选项：
A.A small number of emerging market securities. B.A small number of broad market indexes. C.A large number of emerging market securities. D.A large number of board market indexes.解释：
The Risk Metrics approach is a delta-normal model that requires the returns to be approximately normally distributed, while the historical simulation model requires much less stringent assumptions. The returns on a portfolio with small number of securities is less likely to be normally distributed than a larger portfolio and an emerging markets index is less likely to be normally distributed than a broad market index. Therefore the historical simulation approach will most likely provide a better VaR estimate than Risk Metrics for a portfolio with a small number of emerging market securities.
