预期报酬率

=(-0.1)×0.15+0.14×0.20+0.20×0.40+0.25×0.25

=0.1555

方差=1.29%

标准差=11.35%

标准离差率=0.1135/0.1555=0.73

8.

A股票期望收益率=(40%+20%+10%+5%+15%)/5=18%

A股票方差

=0.2×(40%-18%)2+0.2×(20%-18%)2+0.2×(10%-18%)2+0.2×(5%-18%)2+0.2×(15%-18%)2=1.46%

A股票标准差=12.08%

B股票期望收益率=(20%+15%+5%+8%+10%)/5=11.6%

B股票方差

=[(20%-11.6%)2+(15%-11.6%)2+(5%-11.6%)2+(8%-11.6%)2+(10%-11.6%)2]/5

=0.28%

B股票标准差=5.29%

A股票和B股票的协方差

=[(40%-18%)(20%-11.6%)+(20%-18%)(15%-11.6%)+(10%-18%)(5%-11.6%)+(5%-18%)(8%-11.6%)+(15%-18%)(10%-11.6%)]/5=0.592%

A股票和B股票的相关系数

=0.592%/(5.29%×12.08%)=0.9264

组合的期望收益率=18%×60%+11.6%×40%=15.44%

组合的方差

=60%×60%×1.46%+40%×40%×0.28%+2×60%×40%×0.592%=0.85%

组合的标准差=9.22%

9.

(1)

A期望报酬率20% 标准差 0.1

B期望报酬率22.5% 标准差 0.175

(2)

AB协方差=-0.0175

相关系数=-1

(3)

组合的期望报酬率=21.25%

组合的标准差=3.75%

(4)

Wa=64%, Wb=36%

(5)

WA=68% WB=32%

10.RA=5%+0.75×(17%-5%)=0.14

RB =5%+0.90×(17%-5%)=0.158

RC=5%+1.40×(17%-5%)=0.218

11.

(1) =2×40%+1.5×30%+0.5×20%+1.0×10%=1.45

(2)假设调整后A股票所占比重为X,则D股票所占比重为Y

2×X+1.5×30%+0.5×20%+1.0×Y=1.15

2X+Y=0.6

同时

X +30%+20%+Y=1

X+Y=0.5

X=0.1

Y=0.4

12.

V=8%×1000×(P/A,7%,10)+1000×(P/F,7%,10)=80×7.024+1000×0.508=1069.6

如果预计市场利率将提高,则愿以更低的价格购买它,如果预计市场利率将下降,愿意以更高的价格购买它。

13.

8%/2=4%

10%/2=5%

V=100000×4%×(P/A,5%,7)+100000×(P/F,5%,7)

=4000×5.786+100000×0.711

=94244>94000

值得购买

5% 94244

I 94000

6% 88828

运用插值法计算R=5.05%

IRR=10.1%

14.

(1)KS=D1/P0+g=1.32×(1+8%)/23.5+8%=14.7%

(2)V=D1/( KS–g)=1.32×(1+8%)/(10.5%-8%)=57(元)

(3) 要求的收益率<股票的预期收益率,应投资该公司股票

15.

(1)V=1.5/(16%-6%)=15(元)

(2)V=1.5×(P/A,16%,3)+1.5×(1+6%)/(16%-6%)×(P/F,16%,3)

=13.6
