How to calculate/reconcile conflicting P/E ratios?
The user who wrote the Zerohedge item: The CBS article: The Quora estimate is similar to the Zerohedge one (estimated a round value of 1000 PE and a price of 70-80). Note that it was 30 days after the first 2 items you quoted. You used the CBS numbers except you used the zerohedge price.  It depends on which earnings were for each calculation. Past or future. The CBS numbers make the most sense because you can trace where they come from based on the links in their article.  CBS based their price on the estimates made the day before the stock went on sale. The price in the zerohedge item was based on the early trading numbers.
