It's interesting to me that they don't own the new building like they do the current one, but instead are leasing it with the option to purchase. In any event, I'm not speculating that it will go down like in the case of GM. I'm only trying to encourage people not to be so close minded about all the various options that could take place. It's been my experience that it isn't the things you are certain about that kills your investment. It's the things you haven't even thought about that does.
GM declared bankruptcy. This invalidated current share value and allowed the company to issue new shares once out of bankruptcy.
GSEs are in conservatorship. Completely different animal. If the companies go into receivership, they must, under the law stop operating. They can not then issue new shares the way GM did.
The only way capitalismforever would be right is if the GSEs declared a chapter 11, which is pretty unlikely.
