I wanted to plot a PE vs Time to measure the average PE value of a stock. Shall I use a historical PE or Trailing 4Q PE?
My concern is price always fluctuates with earnings of company. If company get good earnings in a quarter, stock price might surge 10%.
To keep the data accurate, I am thinking of using trailing 4Q PE.
So would like to seek for your opinion and advise on which is a better and more accurate approach. Thanks.
