Fannie Mae-No Politics (FNMA)

[SREZ]

Follow up as to WHY Capital Group/PRIMECAP/Fairholme have been meaningfully exiting JPS (primarily the liquids FNMAS/FMCKJ) over the last quarter. Could it be:
(1) redeploy capital potentially into a better investment/idea;
(2) admit an investing mistake;
(3) Insider info (especially Capital Group) on Negative news from the USG/Treasury/FHFA;
(4) new portfolio management with a new perspective on a Losing legacy holding;
(5) tax reasons (i.e. gains elsewhere to offset losses 'created');
(6) to pay off some party for some future action (whether $$$, or politically)/minimize 'headline risk';
(7) or it is perceived as a truly dead-money investment that is currently priced more than what it is ultimately worth?
Again, Why seemingly NOW and AT these extremely LOW valuations?
TIA!
