Freddie Mac is trading 4.08% lower at $3.76, with no clear company-specific catalyst identified for the October 2 decline. - Major indexes were moving higher, so the drop does not appear to track the broader market. - A reported FHFA plan to move to two-bureau credit reports applies to both Freddie Mac and Fannie Mae, but coverage does not link it to the share-price move. - The September mortgage-rate update is prior context, not a confirmed cause.
