同学你好，A本身没有错，但是A不是CAPM模型的假设，和这个题无关。CFA考试中，很多选项并不是说它本身的说法是错误的，很多时候只不过是和题干问到不相关而已，所以要认真读题，要明白考点是什么，很明显这道题的考点是CAPM的假设。

shimin助教说A项不严谨，谁对啊？A选项的说法不严谨，风险厌恶型的投资者既可以投资无风险资产，又可以通过无风险利率融资（borrow at risk-free rate)再去投资风险资产，所以不一定是持有risk-free asset，也可以是通过举杠杆获得risk-free asset。

B.A high-risk stowhiis measurestanrviation of returns will have high expectereturns in equilibrium. C.All investors who take on risk will holthe inticrisky asset in their portfolios. C is correct.Statement C is one of the CAPM's assumptions. A risk-averse investor woulaccept more risk only when a higher expectereturn is guarantee The CAPM assumes all investors are risk-averse. 可以一下这个题吗

C可不可以翻译成，所有承担风险的投资者都持有一样的风险资产。这句话不太理解，为什么会持有相同的资产呢？具体对应capm的哪一个假设？
