NO.PZ2015122801000064 问题如下 Chloe wants to use the vinscount mol anthe CAPM to value stocks. Whiof the following is most likely to crease the estimatevalue of a stoif all other factors keep constant? A.increase in the expectegrowth rate of vin. B.increase in the expectevin C.increase in the stock's systematic risk. C is correct.Other things equal, using the CAPM, increase in the stock's systematic risk woulincrease the requirereturn on equity ancrease the present value of the value of the stock. Value of sto= / (r - g).C是正确的。本题考察的是两个公式的运用红利折现模型V = /(r – g)， 资本资产定价模型 r = rf + β*（rm – rf）A，红利增长率g上升，由公式1可得股票价值上升。A错B，红利增长，由公式1得股票价值也上升。B错。C，系统性风险上升，代表公式2中β上升，则r上升。公式1和2一起可得，股票价值下降。C正确。 r = rf + β*（rm – rf）β代表系统性风险 是老师是在哪里有提到，是讲义的哪里呢

Whiof the following is most likely to crease the estimatevalue of a stoif all other factors keep constant? 正确答案是: C A increase in the expectegrowth rate of vin. B 不正确increase in the expectevin C increase in the stock's systematic risk. 数据统计(全部) 做对次数: 2859 做错次数: 1112 正确率: 72.00% 数据统计(个人) 做对次数: 0 做错次数: 1 正确率: 0.00% 解析 C is correct. Other things equal, using the CAPM, increase in the stock's systematic risk woulincrease the requirereturn on equity ancrease the present value of the value of the stock. Value of stock = / (r - g).
请问为什么A不对？
CAPM是什么的缩写简称呢？返回去翻讲义翻了半天没找到
