You might be shocked, and maybe commit suicide after you see what might be about to happen.
Federal reserve closed Bond markets closed
All Monday.
If your going to make big changes for the GSEs you certainly do not want MBS trading to be going on. You have to reassure the markets that everything is going to be alright.
The Federal Reserve is not going to wait for retail traders to cover shorts in FNMA and FMCC to act. Nor will they wait for retail investors on the sidelines thinking about getting into the stocks.
With a 3 day weekend for the MBS market; this is a VERY VERY bad time to be short or on the sidelines.
