Current 2005 EPS estimate is $3.49/share, or almost $1-Billion. That's growth of about 150%. If you project that growth into 2006 (insane, but people rationalize stuff like this, especially with a company this young), that's about $8.75/share, or a P/E of 21 at the current price of around $190.
That's the kind of rationalization you are against when you short a cult. Until they stumble or warn, it's more like religion and less like finance.
