Fair Isaac is trading at $676.46, down 19.55%, after FHFA announced a unified mortgage pricing grid giving VantageScore equal standing with FICO Classic for loans sold to Fannie Mae and Freddie Mac.

  • The policy raises concerns that lenders could use VantageScore instead, weakening Fair Isaac’s position in mortgage scoring.
  • Shares closed at $840.89 on September 28, extending recent weakness.
  • Multiple reports link the selloff to the announcement; broad-market moves are comparatively modest.
