1X股票篇的内部收益率=2/25=8%
2 19%折现率,股票投资的净现值=1.72/(1+19%)+2.5/(1+19%)^2+27/(1+19%)^2-22.2=0.0772
20%折现率,股票投资的净现值=1.72/(1+20%)+2.5/(1+20%)^2+27/(1+20%)^2-22.2=-0.2805
设置y股票的内部收益率为r,
1.72/(1+r)+2.5/(1+r)^2+27/(1+r)^2-22.2=0
R=19%,1.72/(1+19%)+2.5/(1+19%)^2+27/(1+19%)^2-22.2=0.0772
R=20%,1.72/(1+20%)+2.5/(1+20%)^2+27/(1+20%)^2-22.2=-0.2805
(r-19%)/(20%-19%)=(0-0.0772)/(-0.2805-0.0772)
R=19.22%
