1204 ET - Fair Isaac is dealing with two key negative developments, Deutsche Bank says in a note. Analyst Faiza Alwy says FHFA director Bill Pulte indicated that competitor VantageScore's 20 point discount to FICO has been removed and both scores will now be treated the same by the GSEs. "This would likely in and of itself result in higher number of mortgages that will see favorable pricing with VS4 vs. FICO Classic," Alwy says. Additionally, Rocket Mortgage said it will become the first mortgage lender to use VantageScore 4.0 as its preferred credit scoring model for all eligible loans, and during 4Q will default to VS4 for mortgages delivered to the federal housing agencies, VA home loans and any other eligible mortgages, according to Alwy. Fair Isaac tumbles 27%.
