Billionaire investor Bill Ackman is stoking new speculation that the Trump administration could end one of the oldest fights on Wall Street by loosening the federal government’s grip over Freddie Mac (FMCC) and Fannie Mae (FNMA).

Shares of Fannie Mae and Freddie Mac , the mortgage giants under U.S. government control since 2008, surged to multi-year highs on Friday after federal agencies revealed a framework for their "orderly" release from conservatorship.

Why Ackman sees 2025 as the turning point for these government-backed giants--and how investors could profit big.

Bill Ackman expects U.S. President-elect Donald Trump to remove Fannie Mae and Freddie Mac from conservatorship, potentially making them private companies again, the billionaire investor said on Monday.
