The expectereturn of market portfolio is 3%*(10%) + 12%*(45%) + 14%*(0.45) = 12%. Accorng to the CAPM, the expectereturn on the risky asset is 5% + 1.2*(12% - 5%) = 13.4%. Because the analyst's forecast return on the risky asset is less thits expectereturn rivefrom CAPM, the asset is overvalueanthe analyst shoulsell it.可以一下吗。。。。
