Fannie Mae is trading 4.3% higher at $5.06 today. The rise comes amid continued expectations for large-scale MBS purchases, following FHFA Director Bill Pulte's September 18 statement authorizing up to $200 billion. Further boosting sentiment, Pulte on September 23 mandated Fannie Mae and Freddie Mac to accept VantageScore 4.0, impacting how mortgage-backed securities are scored and submitted.
