Fair Isaac Drops as Pulte Lets Fannie, Freddie Use VantageScore

Shares in Fair Isaac Corp., known colloquially as FICO, declined after federal regulators said government-sponsored mortgage entities Fannie Mae and Freddie Mac will be able to use a second firm when determining borrowers’ creditworthiness.

FICO shares slid 8.9%, the most since May, to $1,703.17, the lowest in six weeks.
