FNMA commons being risky, quick summary
Hedge funds are buying preferred, US Treasury holds preferreds as bailout collateral. If, IF, the fed decides to butcher Fannie n Freddie, preferreds will be able to sell first, commons would be screwed, similar to the General Motors situation a few years ago
Ken may have the links I sent him in his archives, im mobile, tough to find it right now
Commons are very tradeable for sure in the short-mid term
IMO
