问题如下：
With respect to return-generating models, the intercept term of the market model is the asset’s estimated:
选项：
A.
beta.
B.
alpha.
C.
variance.
解释：
B is correct.
In the market model, Ri =αi +βiRm +ei, the intercept, αi, and slope coefficient, βi, are estimated using historical security and market returns.
是否可以这样理解：return generation model 属于一个大的概念范畴，multifactor models和market model都属于这个大概念，而market model属于multifactor models的特例。若考察多个β，就属于multifactor models，若考察一个系统性风险影响的β，就属于multifactor models中的特例capm模型；若考察系统性风险β与非系统风险α的影响，就属于multifactor models中特例market model。
