NO.PZ2018110601000021 问题如下 Which of the following statement regarng factor-baseasset allocation is least appropriate? Factors are typically baseon market premiums ananomalies A common wto construfactors is self-financing investment. Factors are typically fferent from the funmentor structurfactors used in multi-factor mols. C is correct 考点：factor-based asset allocation 解析：Fama-French三因素模型是典型的factor-baseasset allocation，既包含market premium，又包含size和book-to-market两个基本面因子（funmental factors/ anomalies）。构建这些因子的方法是self-financing investment，或者称作zero llar investment，例如：Size factor return=Small-cstoreturn−Large-cstoreturn。 请问C为什么不对呀？
