In the week before 2026-10-11, Michael Burry made a trade move in both Fannie Mae and Freddie Mac stock.

The test is whether Burry made a trade or position change in both Fannie Mae and Freddie Mac securities (buying, selling, or trading options) during roughly 2026-10-04 to 2026-10-11. Burry's own post saying so is not enough on its own. Corroboration would be a regulatory filing, broker or fund records, detailed contemporaneous trade disclosures, or independent reporting confirming the trades. TRUE: corroborated evidence of a move in both stocks during that week. MOSTLY TRUE: moves in both are corroborated but fall slightly outside the week (within a few days). MIXED: a move is corroborated in only one of the two. MOSTLY FALSE: the moves happened, but well outside that week. FALSE: positive evidence shows no change in his positions in either stock during the period, such as filings or his own later statements.

7. E7 Burry cites treasury dilution risk in shift to Fannie and Freddie preferred stock TradingView (Seeking Alpha news) · 12 October 2026

   “'The Big Short' investor Michael Burry is switching from common stock holdings of Fannie Mae FNMA and Freddie Mac FMCC to junior preferred shares amid dilution concerns.”

Several outlets report that Burry said he sold his Fannie Mae and Freddie Mac common stock and bought preferred shares around October 11 (E2, E3, E5, E6, E7); E1 reports only that he said he made a move in both. Several reports attribute the trades to Burry's own Substack or X posts and replies (E1, E2, E5, E6); none of the evidence cites filings or broker records. None gives trade dates (E3, E4). The criteria say Burry's own post is not enough, and no evidence cites a filing, broker record or other documentary confirmation of the trades or their dates, so the claim cannot be resolved.
