问题如下:
Alena,CFA, was updating her firm’s projections for US equity returns.If she believed that in the long run that the US labor input would grow by 0.9% perannum and labor productivity by 1.5%, that inflation would be 2.1%, that the dividend yield would be 2.25%, and that there would be no further growth in P/E, what is likely to have been her baseline projection for continuously compounded long-term US equity returns?
选项:
A. 6.75%
5.5%
C.5.85%
解释:
A is correct
解释:
在长期,一国股票市场的增长率等于该国GDP的增长率(本题P/E增长率为0也证实了这一点)。那么本题就等于计算该国GDP的增长率。
Her baseline projection is likely to have been 6.75% = 0.9% + 1.5% + 2.1% + 2.25%
依照公式可得:. 6.75% = 0.9% + 1.5% + 2.1% + 2.25%
看了大家的问题之后,这道题我是这样总结的,但是还有一点问题。
首先这道题结合了两个知识点GDP的composition和GK模型(equity earning的composition)。
1、%△GDP=labor productivity+labor force(题目中的labor input)=0.9%+1.5%=2.4%
2、GK model:E(Re)= D/P+%△E-%S+%P/E = 2.25%+%△E-0+0 = 2.25%+%△GDP+%△E/GDP
在这里%△GDP+%△E/GDP就是%△E,我理解%△E是nominal return rate包含inflation rate,可是这个inflation rate没有直接包含在刚刚计算的%△GDP中吗?%△E/GDP也等于0吗?
2、GK model:E(Re)= D/P+%△E-%S+%P/E = 2.25%+%△E-0+0 = 2.25%+%△GDP+%△E/GDP
