NO.PZ2018110601000015问题如下 A risk parity asset allocation approais useto allocate asset classes in a portfolio. Among the five asset classes, foreign equities have the highest risk, anhave the highest covarianwith other asset class returns. In this case, the weight of foreign equities shoulbe: smaller th20% equto 20% greater th20% A is correct. 考点：risk parity asset allocation 解析：在risk parity asset allocation方法中，每个资产对于组合总风险的贡献度都是相等的，总共5类资产，因此每个资产对于组合总风险的贡献度占比都为20%。由于foreign equities在5类资产中的风险最大，因此foreign equities的权重占比应当小于20%。 老师，请问equity与其他资产cov，可否理解为equty与portfolio的cov最大？ 因为按照左边等于右边，如果cov（r1，rp）大，w1则小，右边不变。

从定量角度分析，σp一般是多少？，无法比较σp的平方和分母cov（Ri，Rp）的大小，没概念
