摘    要:基准组合具有某种正交特性(orthogonality properties)。把管理者组合(P)分解为基准组合(B)和积极管理的组合(A),其中基准组合不包含管理者的私人信息。用M代表市场组合,研究得出:cov(B,A)=0,cov(A,M)=0。进一步推导得出:β[P,B]=1,β[P,M]=β[B,M]。本文通过对中国开放式基金市场各基金所声称的基准进行实证检验,得出了我国基金市场开放式基金基准组合并不具有正交特性的结果。

关 键 词:开放式基金  基准组合  正交特性

Abstract:Abstract Orthogonality property is a nature of valid benchmark. Manager's portfolio (P) can be disaggregated as benchmark (B) and manager' s active investment judgments ( A ). There is no manager' s valuable information in bench-mark (B). By denoting M as the market proxy, the result is COV(B, A) = 0, COV(A, M) = 0 and β[ P, B] = 1, β[ P, M] =β[ B, M]. From empirical study of benchmark orthogonality properties of mutual funds in China, the research conclusion is that benchmark of mutual funds has no orthogonality properties in China.
Keywords:mutual funds  benchmark  orthogonality properties
