Fannie Mae-No Politics (FNMA)

[house1]

Question.........for someone wanting to invest $1,000 in either common or preferred shares of FNMA right now,
which is the better short term choice? Which type will go up the most first? Preferred because it is a safer, sure par price or common because it is priced lower with more room to grow? If an announcement releasing them from conservatorship happens in February, would the preferred shoot straight up to the $25 par price right away in the case of FNMAS ? Is it logical to think the preferred will multiply faster and then by selling at par, one could buy the commons with additional room to multiply as recap moves forward? Help please.
