同学你好,因为这道题本身就是以一个季度为一期的,所以不需要先换算成EAR。

如果换道题目,以一年为一期,PMT发生在每年末,但是按季度复利,就要先换算成EAR进行计算,注意这里也不需要再除以4了,因为EAR本身就是代表按季度复利的有效年利率了,直接拿来计算即可。

If the requireannurate of return is 6% compounquarterly, the stock’s present value is closest to: A.$31. B.$126. C.$133. B is correct. The value of the perpetuity one yefrom now is calculateas: PV = A/r, where PV is present value, A is annuity, anr is expressea quarterly requirerate of return because the payments are quarterly. PV = $2.00/(0.06/4) PV = $133.33. The value toy is (where FV is future value) PV = FV(1 + r)–NPV = $133.33(1 + 0.015)–4 PV = $125.62 ≈ $126 /sp12 /sp\frac12 /sp21​ 请问这个两阶段模型,第一阶段是后续永续增长的利息折现到t=5,然后用P5再向前折现对吗?P5向前折现为什么不是5次方呢?
