Chinese Abstract: CAPM 所在的资本市场是非完全的,并且是 一 个 Hilbert 空间,我们找出了该市场中 SDF 模仿支付的显式表达式。纯风险证券的局部均衡中,CAPM 公式成立,CAPM … 等价于市场组合恰好为切点组合,并且证券价格的通解在一维空间中。给定投资者的禀赋和均值方差偏好,结合 CAPM 的价格通解,资本市场的均衡条件转化为单变量的方程,从而求得均值方差均衡价格的解析解。证券价格是内生的,全体风险证券是作为 一 个整体被定价的,貌似真实的风险决定收益是局部均衡的产物,其错误在于把市场收益率当成外生的。我们还通过数值例子,分析均值方差决策与无套利的关系,化解不可能前沿的危机,展示贝塔定价导致欧式看涨期权负价格,以及不可以使用贝塔估计权益资本成本。CAPM …English Abstract: The capital market for CAPM is incomplete and is a Hilbert space, we find out the analytic expression …

Chinese Abstract: 风险教条认为资产价格是由某种风险决定的,而均衡定价认为是由供需均衡决定的。基于 CAPM 市场均衡的解析解,我们看到贝塔不是证券的特性。我们指出学者们混淆了时序贝塔和市场贝塔,以及风险教条背离了均衡定价的整体性思想,孤立地看待证券个体的定价。最后,通过分析资产变动对贝塔的影响,我们揭示了诸如贝塔改变而期望收益率不变等与风险教条对立的情形。 … CAPM market equilibrium, we see that beta is not a characteristic of securities. We point out that scholars have confused …
