你好对于翻上去是n来除还是有点不太懂

问题如下：

Sara, a junior equity research in a small securities company, is comparing a company’s value with its peer group. The company, named HomeWithLove, operates in the real estate industry. The information about the company is shown below:

The current stock price as of Jan 2018 is $35

The information about earnings per share of the company is:

The forward P/E of the company’s peers:

Based on the information above, and using the harmonic mean of the peer group forward P/E as the benchmark, which of the following is correct?

选项：

A.

Compared with the benchmark, HomeWithLove is undervalued.

B.

Compared with the benchmark, HomeWithLove is overvalued.

C.

Compared with the benchmark, HomeWithLove is fairly valued.

解释：

A is correct.

考点：考察Forward P/E相对估值法，考察Harmonic mean的计算。

解析：

Harmonic mean的计算公式为：

$X_H=\frac n{\displaystyle\sum_{i=1}^n\frac1{x_i}}=\frac5{\displaystyle\frac1{6.7}+\frac1{7.2}+\frac1{13.2}+\frac1{4.5}+\frac1{5.5}}\approx6.51$

则比较的Benchmark为6.51

而当前Homewithlove的股票价格为35，其2018（E）年的EPS为7.0，所以其Forward P/E为35/7=5.

当前由于HomeWithLove的Forward P/E小于行业的平均Forward P/E所以公司相对被低估。
