Their P/E is 317.
I put it at 30-40.
That is 1/10th of their current price.
I don’t see them losing 90% of their value. But their stock price has to come down, or at least stagnate for a long time until the P/E becomes more sane.
UPDATE: originally posted on Sept 10, 2012. As of Oct 19, their P/E is 293.
