摘要 在尾部条件期望(TCE)基础上,考虑投资者的真实风险感受,研究了一种新的风险度量方法———Shortfall风险度量,并在一致性公理下研究了它的一些统计性质,最后在多元椭球分布下得到了证券组合的Shortfall风险,还在多元t分布下得到了证券组合的Shortfall风险的数值结果。 On the basis of tail conditional expectation, a new risk measure of portfolio called shortfall is discussed. Some statistical properties are derived under the framework of coherent risk measure. Shortfall risk of portfolio with multivariate elliptic distributions asset returns and some numerical result for multivariate t distribution are obtained.
