What Headley Lamar said..
Your trying to over analyze this and make it too complicated. GAAP EPS is what will be used by the majority of the market.
If the few folks that want to use pre GAAP EPS to value the stock go for it.. but don't be disapointed when most don't.
This is a double whammy.. 1.) It just looks bad, shows their bookkeeping is jacked up and that their auditor screwed up 2.) EPS is down significantly.
If only 10% of shareholders sell, and the majority of the market is expecting a sell off, you should probably expect the worse.
