Fair Isaac broke a quiet tape

Tuesday, 29 September 2026. The hundred on the software monitor. Not a price target. Not investment advice.

The hundred fell 0.14%

The size of the book move and the story of the day are different things. Fair Isaac, rank 50, is the laggard on the monitor, at $617.87, down $223.02, or 26.52%. Duolingo, rank 80, led the hundred, at $142.62, up $8.32, or 6.20%. The next gain inside the same list was ServiceTitan, rank 85, up 6.01% to $63.52. The monitor does not say why ServiceTitan moved.

Infrastructure finished up 0.23% across 44 names. Application finished down 0.44% across 56. Infrastructure led by 0.66 points, and the book finished 0.05 points ahead of IGV, which was down 0.20%. Breadth was 44 up, 51 down, and 5 unchanged. Microsoft, the largest name, was $508.96, up 0.08%. Oracle, rank 3, was the move among the largest names, $137.79, up 3.91%. Oracle’s 29 September release introduced Fusion Claw, which it calls a governed agentic execution runtime, with 25 new applications and a portfolio it counts at 75.

Without Fair Isaac, this is a quiet close. The sleeves split by less than a point, the ETF sat just behind the book, and the latest desk note is still empty.

Fair Isaac and one pricing grid

Fair Isaac is application software, number 50 of the hundred. The monitor’s last close is $617.87, down 26.52%. Investopedia reported the same day that the Federal Housing Finance Agency is changing mortgage pricing at Fannie Mae and Freddie Mac. It reported that FHFA Director Bill Pulte wrote the two enterprises are moving from two pricing grids to one, with VantageScore joining the existing FICO Classic grid. The sentence Investopedia quotes from that post is: “Instead of two separate pricing grids, which makes zero sense, Fannie and Freddie are hereby moving to ONE PRICING GRID with VantageScore joining the existing FICO Classic pricing grid.”

This is a policy headline, not a Fair Isaac earnings release. No revenue, net retention, free cash flow, or margin from a company filing was opened for this update, so none is included. No price target is included. The only market figure is the one on the software monitor.

If that account is the one the market traded, the change is the grid. A loan scored with VantageScore and a loan scored with FICO would be priced on the same Fannie and Freddie grid, instead of on two. The 26.52% decline is the hundred’s print on the day that report ran. Fair Isaac did not, in the sources opened here, put out a same-day revenue or guidance number to set beside it.

Infrastructure led by 0.66 points

The book is 100 names, 56 application and 44 infrastructure. On 29 September the application sleeve was down 0.44% and the infrastructure sleeve was up 0.23%. The hundred as a whole was down 0.14%. IGV was down 0.20%, and the book finished 0.05 points ahead of that ETF. Breadth was soft in the count and small in the average: 51 names down, 44 up, 5 unchanged.

The sleeves did not move together. Infrastructure led application by 0.66 points. The application damage was one name. Fair Isaac’s 26.52% drop is inside that sleeve. Duolingo’s 6.20% gain is inside it too, and it did not turn the sleeve positive. Microsoft did not drive infrastructure. Oracle, up 3.91%, did more of the visible work at the top of the list, and that move lines up with a product release rather than a new earnings print.

No fresh earnings figure for the book was opened for this draft. No desk note is filed. The copy line points at an Adobe item, “What Adobe Stock’s AI Partnerships Mean For Shareholders.” Adobe, rank 16, closed at $233.17, up 0.93%. The title is recorded here. The piece was not opened, so it is not summarized.
