9)R=10%+1.5*(18%-10%)=22%
D(1)=8*(1+8%)=8.64
股票价值=D(1)/(R-g)=8.64/(22%-8%)=61.71

8)(10-0.6)/(1+0.3)=7.23

7)???

6)2*(1+5%)/(10%-5%)=42

5)预期收益率=18%*70%+8%*30%=15%
标准差=???

4)R=10%+1.5*(18%-10%)=22%
D(1)=8*(1+8%)=8.64
股票价值=D(1)/(R-g)=8.64/(22%-8%)=61.71

3)(12+0.2*4.50)/(1+0.2+0.2)=8.64

2)期望收益率=60*25%+50*50%+30*25%=47.5
(25%+50%+25%)/3=33%
标准差={[(25%-33%)^2+(50%-33%)^2+(25-33%)^2]/2}^0.5=0.14

1)???

以上计算结果均可能出现差错,请慎用。
