.4。代入计算得到σp≈√(0.36*324+0.16*64+2*0.6*0.4*(-72))≈√(116.64+10.24-43.2)≈√83.68≈9.15%。最接近的选项是a)8.1%。7.c解析思路：压力测试是通过模拟极端但可能的市场情景，评估投资组合在这些情景下的表现，目的是识别潜在的脆弱性和风险点，确保投资组合能够承受不利的市场冲击。8.b解析思路：VaR的一个主要局限性在于它假设回报率服从正态分布。然而，实际金融市场的回报率分布往往存在“肥尾”现象（即极端事件发生的概率高于正态分布预测），VaR无法有效捕捉这种尾部风险。9.d解析思路：限制单一行业投资比例的约束，目的是为了避免投资组合过度集中于某个特定行业，从而降低该行业特有的非系统性风险对整个投资组合的影响。10.c解析思路：在持有的股票上使用看跌期权，相当于购买了未来以约定价格卖出股票的权利，可以锁定最低卖出价格，从而在股价下跌时保护投资收益，属于对冲风险的行为。11.b解析思路：企业风险管理（ERM）是一个组织范围内的框架，用于识别、评估和管理各种类型的风险（包括财务风险、运营风险、战略风险等），以实现组织目标。这与选项b的描述最一致。12.c解析思路：根据风险控制的原则，在评估是否添加新资产时，不仅要考虑其预期回报，还要考虑其风险以及与现有资产的关联性（相关性）。将风险预算或相关性纳入考量有助于维持或改善组合的整体风险特征，而不仅仅是看回报或单一风险指标。13.d解析思路：限制投资于信用评级低于投资等级（即高收益或垃圾债券）的资产，主要是为了降低投资组合面临违约风险的可能性，从而控制信用风险。14.a解析思路：敏感性分析用于衡量投资组合价值对某个特定风险因素（如利率、汇率、股价）变化的敏感程度或影响大小。15.a解析思路：ConditionalValueatRisk(CVaR)衡量的是在VaR损失发生的情况下，额外的平均预期损失。因此，在VaR的基础上加入CVaR提供了一种更全面的风险度量，特别是对尾部风险的关注，使其通常被认为比单独使用VaR更为保守。16.c解析思路：ValueatRisk(VaR)提供了一个简洁的、易于理解的指标，表明在特定置信水平下（如99%），投资组合可能损失的最大金额。这对于向管理层
