The Big Short: How Bill Ackman and Michael Burry Threw a Spotlight Back on Fannie Mae—and What It Means for Investors
On Monday morning (ET) an image circulated among traders: a quote from Bill Ackman on X and the Federal National Mortgage Association (FNMA) slipping above its 20-day moving average. The shared screenshot, Ackman’s blunt language calling the stock “stupidly cheap, ” and a visible technical shift combined to lift FNMA shares meaningfully in a matter of minutes — a small scene that captured a larger tug-of-war over the future of America’s mortgage backstop and the mood of the market around it. The big short echoes through the conversation as Michael Burry, identified with the phrase, added his voice to the debate.
Why did FNMA jump and why are investors listening now?
The immediate lift in FNMA followed Bill Ackman’s public post labeling Fannie Mae shares a “10x opportunity” and calling the valuation “asymmetry at its best. ” That message attracted momentum traders, value investors and speculators, shifting interest into the over-the-counter stock. Technical indicators also shifted: the stock vaulted above its 20-day moving average and its 14-day relative strength index sits at 56, signaling room to the upside. At the same time, FNMA remains more than 35% below its level at the start of the year, and broader commentary notes that Fannie Mae and Freddie Mac have each fallen roughly 40% this year — numbers that help explain why a high-profile endorsement reverberated so loudly.
What does The Big Short’s Michael Burry add to the conversation?
Michael Burry, known for his association with The Big Short, replied to Ackman’s comments with his own bullish signal, writing that the market reaction was unusually rare. Burry’s involvement has a particular resonance: he previously criticized the two mortgage giants for their role in the 2008 housing collapse but disclosed a sizable stake in both Fannie and Freddie in December 2025. His public shift, alongside Ackman’s stance, reframes how some investors are thinking about the firms and draws renewed attention to the possibility that deeply discounted valuations could produce outsized returns.
Could a re-listing or policy change unlock value, and what are the practical steps?
Investors are betting on structural outcomes that would change the companies’ profiles: speculation centers on a potential exit from government conservatorship and a re-listing to a major exchange, moves that would require massive recapitalization and could include a partial initial public offering. The Federal Housing Finance Agency (FHFA) is described as moving toward a utility-type model; if Fannie Mae were to operate again as a private, dividend-paying entity, that is framed as an ultimate bullish catalyst. Market participants are assessing those scenarios alongside everyday trading signals: Barchart lists the consensus rating on FNMA as “Moderate Buy, ” with a mean target of about $13 — a figure that implies roughly 90% upside from recent levels, on its face a powerful numeric argument for buyers weighing the risk-reward trade-off.
But the path to any of those outcomes involves complex steps. Recapitalization at scale, regulatory clearances, and the logistics of a re-listing are cited as prerequisites; investors are watching how commentary from influential managers and shifts in market technicals translate into sustained buying or merely a short-term repricing.
Back on the trading desk where Monday’s screenshot first spread, the mood remained a mixture of cautious optimism and skepticism. A portfolio manager who had been watching mortgage-related names noted the unusual combination of public endorsements and technical strength that can amplify flows into an already volatile corner of the market. Bill Ackman’s refrain — that high-quality assets can be exceptionally cheap in choppy markets — and Michael Burry’s rare public affirmation have together forced a reappraisal of Fannie Mae’s prospects.
As the day closed, the scene that opened this story had shifted in meaning: a single social-media post no longer felt like noise but like a signal in a larger policy-and-market experiment. For traders who remember the big short as a paradigm for contrarian profit, that history now acts as both a caution and a prompt. The question left hanging is whether this renewed spotlight will produce a sustained remaking of Fannie Mae’s market position or remain an episodic surge driven by high-profile conviction.
