A is correct.Expectereturn on CAPM = 8 + 0.5(16 - 8) = 12%Estimatereturn on sto= (32 - 30 + 4) / 30 = 20%The estimatereturn is higher thexpectereturn on CAPM, incating ththe stois unrvalue investor shoulbuy it. 不是很理解market expereturn和CAPM计算出来的return分别是什么？market expereturn不是市场上大家认为的收益率么？如果大家认为应该值的更高（market expereutrn更大），那不就是股票被低估吗？怎么答案跟我想的相反
