Fannie Mae


Freddie Mac

were once again the worst performers of the financial sector Thursday, one day after U.S. regulators instructed the government-sponsored enterprises to delist from the

New York Stock Exchange


Fannie and Freddie

shares fell more than 20% after the Federal Housing Finance Agency (FHFA) said Wednesday it has directed both to delist from the NYSE.

The FHFA said the determination to direct delisting is related to stock exchange requirements for maintaining price levels and curing deficiencies, and "does not constitute any reflection on either enterprise's current performance or future direction, nor does delisting imply any other findings or determination on the part of FHFA as regulator or conservator."

Fannie and Freddie expect that the delisting of their common and preferred stock from the NYSE will be effective 10 days after informing the

Securities and Exchange Commission

, which would come on July 8. After delisting from the NYSE, both stocks will move to the over-the-counter market, the companies said.
