Chicago, IL -- (SBWIRE) -- 07/27/2012 -- Federal National Mortgage Association (OTC:FNMA) was showing signs of life over the past two sessions, but today we watch the corporation's share price retreat to recently established support levels. Although over 1.4 shares have traded today, it seems that the bears have their claws firmly entrenched in FNMA. Share prices could have been impacted by Zillow.com reporting that housing prices bottomed out earlier this week. FNMA shows no sign of a rebound as we watch the week come to a close.
