Weekly Roundup: FICO Jumps, Carnival Slides, Pfizer Soars

On this episode of Stock Movers, we take a look at some of this past week's biggest gainers and decliners:

- Fair Isaac (FICO) surged after the credit scoring company unveiled new pricing models that will allow mortgage lenders to calculate and distribute FICO Scores directly to borrowers. Lenders currently rely on the three nationwide credit bureaus, TransUnion, Equifax and Experian, to provide FICO scores. Under Fair Isaac's new offerings, lenders can choose to avoid credit bureaus' markup fees, though they would pay Fair Isaac $33 per borrower per score when a FICO-scored loan is closed.

- Carnival (CCL) shares slumped this week following the release of third-quarter earnings. The cruise line's net yields guidance for the fourth quarter trailed some expectations, and comments on cost headwinds in 2026. Still, analysts defended the stock, and see opportunities to offset cost pressures. Shares had been up 23% this year heading into Monday's print.

- Pfizer (PFE) helped lead pharmaceutical stocks to their best week in 23 years as a drug-pricing and tariff deal with the US government helped ease an overhang that’s been weighing on the sector for most of the year. Pfizer spurred the group’s advance on Tuesday when it agreed to slash some of its drug prices for Americans enrolled in the Medicaid insurance program in exchange for a three-year reprieve on import tariffs. The New York-based company also agreed to invest $70 billion in the US as part of an agreement with President Donald Trump.
