If you look at the 10K earnings releases (4th Q results) from the last 5-6 years for Fannie Mae, you will see that it is typically reported on the last Wed, Thur, or Fri of February. Freddie Mac's also is typically reported at the end of Feb or first week of March.
I'm not really sure why anyone expects these to be significantly different this year? Perhaps I can be enlightened? If your answer is Google finance (or any other website) told you so, then unenlightened I will remain.
