解释：
PEG的计算，PE是否有规定要用forward还是trailing？
根据讲义，PEG是PE ratio除以expected earning growth rate。而讲义的例题给出的PE ratio也是forward PE。
若出于匹配原则，既然g是expected，所以PE也应该用forward。
如果题目没有明确指出，计PEG可否用trailing EPS？
NO.PZ2018103102000143 问题如下 Kirk, a researcher in a securities company, wants to rank the relative value of companies he covers their forwarPEG ratio. The information on companies are shown below:Accorng to the information above anranking PEG ratio, whicompany is the most attractive one anwhicompany is the least attractive one? Most attractive: Company Least attractive: Company Most attractive: Company Least attractive: Company Most attractive: Company Least attractive: Company B is correct.考点考察应用PEG进行relative value比较首先根据信息计算ForwarP/ECompany A32/1.65=19.4Company B46/1.20=38.3Company C77/3=25.7Company 10/2.5=4然后计算各自的ForwarPEGA19.4/15=1.29B38.3/18=2.13C25.7/22=1.174/7=0.57当用PEG比较时，PEG越小则代表其越被低估。因此按PEG标准，公司最好，公司B最差。 请问为什么计算的是forwarP/E呢？
您好，请问为啥解题时除g时没带百分号？
不用last 4 quarters。
