NO.PZ2015121810000002 问题如下 Last yethe return on Harry Company stow5 percent. The portion of the return on the stonot explainea two-factor macroeconomic factor mol w3 percent. Using the ta given below, calculate Harry Company stock’s expectereturn. Macroeconomic Factor Mol for Harry Company Stock（备注课后题原题，虽然题目形式是问答题，但是建议不用纠结题目形式，了解题目考查角度即可） In a macroeconomic factor mol, the surprise in a factor equals actuvalue minus expectevalue. For the interest rate factor, the surprise w2 percent; for the G factor, the surprise w–3 percent. The intercept represents expectereturn in this type of mol. The portion of the stock’s return not explainethe factor mol is the mol’s error term.5% = Expectereturn – 1.5(Interest rate surprise) + 2(G surprise) + Error term= Expectereturn – 1.5(2%) + 2(–3%) + 3%= Expectereturn – 6%Rearranging terms, the expectereturn for Harry Company stoequals 5% + 6% = 11%. 老师，请问为什么预期收益=5%+6%呢？怎么理解呀
