您好,我想问一下这道题用计算器算npv这样算对吗?CF0=3,CF1=3*1.08,CF2=3*1.08的二次方,CF3=33,I=15%,cpt npv,这样算出来和答案的数字有点出入,所以想来问问这计算过程对不对?谢谢!
老师,能否详细解释一下书本151页,第十三题答案是什么意思?This results from the fact that the factors typically represent what is referred to as a zero (dollar) investment or self- financing investment, in which the underperforming attri-bute is sold short to finance an offsetting long position in the better- performing attribute. Constructing factors in this manner removes most market expo-sure from the factors (because of the offsetting short and long positions)不太理解?为什么会和zero investment,self-financial investment long/short 有关系?
