2.5 yrs until 2018 zero capital level. I think there is still huge political risk here, and sadly courts move too slowly for us longs to be sure that there will be a final ruling before 2018 comes and there is zero capitalization. At that point, you know politicians will start crying for what they will call "another bailout" because doing so will serve the purpose of generating a nationwide debate and news story that will of course consist of mis-information and lies. Just the talk of "another bailout" will give more cover to the banks that want to take the GSEs' business and their for-hire politicians will push for "reform" that benefits banks and screws shareholders.
At some point before the 2018 mark, it is possible that court or other developments might bring the pps back to many shareholders' break even point or beyond. And that would be a chance to exit for anyone interested in trying to avoid a big loss. But that could be just a temporary pop before the politicians manage to succeed in this outrageous theft. It's wrong and disgusting. But there should be one or more chances to make nice profits even if the fair value of these shares is never realized because of gvt malfeasance.
