It did not take much more than a weekend social media post from one of Wall Street’s most closely watched voices to send two of the mortgage market’s biggest names into a sharp rally. Shares of Fannie Mae and Freddie Mac each surged more than 30% in Monday trading after billionaire investor Bill Ackman published a pointed and bullish assessment of both companies on X, drawing immediate attention from investors who have been monitoring the pair’s turbulent year.
What Ackman said
Ackman’s post was characteristically direct. He described the two mortgage finance giants as “stupidly cheap,” framing the investment opportunity as a case of asymmetry at its best — a situation where the potential upside significantly outweighs the downside risk. He went further, suggesting the stocks could rise tenfold from current levels and that such a move could happen soon, a timeline that added particular urgency to his remarks.
He also placed his comments about Fannie Mae and Freddie Mac within a broader observation about the current market environment, arguing that some of the highest quality businesses in the world are presently trading at extremely attractive valuations. In his assessment, this represents one of the best buying opportunities for quality stocks in a considerable stretch of time.
Context behind the rally
Monday’s surge, while dramatic, does not fully erase the difficult stretch both stocks have endured. Despite the day’s gains, Fannie Mae and Freddie Mac shares remain approximately 60% below the peaks they reached in mid-September 2025 — a decline that reflects a steady erosion of investor confidence surrounding the Trump administration’s plans to release the two companies from government conservatorship.
Fannie Mae and Freddie Mac have been under federal government control since 2008, when they were taken into conservatorship during the financial crisis. In the years since, periodic speculation about their eventual release into private hands has driven significant swings in their share prices, as investors attempt to price in an outcome that has repeatedly been discussed but never delivered. The fading of optimism around that process over recent months contributed heavily to the sell-off that preceded Monday’s bounce.
What it means for investors
Ackman’s intervention has clearly reignited interest in both stocks, at least in the short term. Whether that interest translates into sustained momentum depends on factors well beyond any single investor’s opinion — most notably, whether the political and regulatory conditions for a genuine privatization of the two companies begin to take shape in a more concrete way.
For now, Monday’s trading reflects the degree to which markets remain highly sensitive to influential voices when it comes to stocks that carry significant event-driven risk. Fannie Mae and Freddie Mac are not conventional investments, and the path of their share prices will continue to be shaped as much by Washington as by Wall Street.
Anyone considering a position in either company should weigh the full picture of uncertainty that comes with that territory carefully.
