下列关于CAPM和APT的区别错误的是( )。

A．APT强调的无套利均衡原则，其出发点是排除无套利均衡机会，若市场上出现非均衡机会，市场套利力量必然重建均衡；而CAPM是典型的风险收益均衡关系主导的市场均衡，是市场上众多投资者行为结果均衡的结果

B．CAPM是建立在一系列假设之上的非常理想化的模型；而APT的前提假设则简单得多，从而使得APT不但大大减少了CAPM有效前沿的计算量，而且使APT更符合金融市场运行的实际

C．CAPM不仅考虑来自市场的风险，强调证券的风险时用某一证券的相对市场组合的β系数来解释，这只能告诉投资者风险的大小，但无法告诉投资者风险来自何处。而APT不仅考虑了市场本身的风险，而且考虑了市场之外的风险，尤其是多因素套利定价理论考虑证券收益受到多个因素的影响，这对证券收益率的解释性较强

D．APT强调无套利原则，这种无套利均衡定价是通过充分分散化的投资组合的分析而得到的，对单项资产的定价结论并不一定成立；而根据CAPM强调的市场均衡原则，当单项资产在市场上失衡时，在CAPM条件下所有的投资者都会同时调整自己的投资头寸以重建均衡
