NO.PZ2018062002000178 问题如下 Peter collects the following information from three companies in the same instries,Whiof the companies is most likely to unrvalue A. B. C. C is correct.Relative to the others, hthe lowest P/E multiple anthe P/B multiple is tiefor the lowest with Given the lof one price, similcompanies shoultra similP/B anP/E levels. Thus, baseon the information presente C is most likely to unrvalue考点PriMultiple Approach处在相同行业的三家可比公司即规模、行业、发展情况差不多的三家公司，根据一价定律他们的交易价格应该相似，通过相对估值法我们看到C的PE\PB都是最低的，说明他的价格被低估了。 老师，请以此题为例，讲一下什么是一价定律，李老师在视频里一句话带过，根本没讲明白。此题三个公司从什么角度来比较被高估还是被低估啊？
