"Civilian No. 955,436,725, you have been found in a restricted area. You have no more points on your criminal record. You will now be taken the camp for wayward patriots to receive reeducation!"
Facebook's earnings per share are listed on Yahoo Finance at $0.43. If the company were selling at $20 then the Price-to-Earnings ratio would be 46.51($20/$0.43).
Personally that's still too high of a PE ratio for my investment style.
