FICO 9 Volatility - Up and Down 65 Points

[Shooting-For-800]

This makes no sense. 

My Fico9 is like the stock market while my Fico8 has not moved more than 6 points total.

The only changes are new accounts, new inquiries, and utilization +/- maybe 5% (from 12-17%).

I have no lates, all balances are 0% promotions, no card utilization over 49%, 3-5 inquiries.

The odd part is I opened a new Navy card between the 686 and 731 so new accounts/inquiries can't be that impactful.

I am glad it snapped back after last month's nose dive, but what in the world???

Any ideas?

Data below...

 ................ FICO9 ..................... FICO8

5/10 .......... 732 ......................... 724

6/10 .......... 751 ......................... 729

7/10 .......... 686 ......................... 729

8/10 .......... 731 ......................... 730

The only one that looks odd is the 686 reported in the 7/10 report. So you need to compare 6/10 to 7/10 very carefully to see what caused the dip to 686. Then when you find it, confirm by comparing the 7/10 with the 8/10 report.

Here are some possible candidates for differences between FICO 8 and FICO 9:

-paid collections not counted in 9
-unpaid collections given more weight in 9
-medical collections given less weight in 9
-rental history counted in 9
-recent inquiries given less weight in 9
-average age of accounts given less weight in 9
-no. of accts reporting balance given more weight in 9
-premium for open as opposed to closed installment loans reduced in 9
-installment balance to loan ratio given more weight in 9
-9 more sensitive to revolving utilization

Thanks for your reply.

Not one of those areas should have affected me.

Any other ideas?

As SJ said, something is different on your 7/10 report compared to the 6/10 or 8/10 reports.  Have you compared the reports or are you just looking at the scores?  You need to figure out what that is if you want your answer.  Scores are based only on report data.  Significantly changed score means a data change happened.  Data gets fed in, a score spit out.  The only way the score is going to significant change is if the input data changes.

There are no major differences as stated above.

I have the reports.

If it had anything to do with lates, inquiries, or new accounts, it would not have rebounded the next month.

(I have no lates and my inquiries and new accounts are HIGHER now than when score was lower)

Overall balances are higher now than when score was lowest (still under 15%).

Fico 8 never went down a point.

I understand 5 points even 10 points but 65 points???

I think it was just a glitch.  A glitch that cost me an inquiry at NFCU.

Glitch or no glitch, the algorithm was seeing different data in order to produce scores 65 points apart.  If you can't see the difference, I suppose chalk it up to a glitch where the algorithm was seeing something different for whatever reason.

Surely there would be some kind of an alert for that big of score drop?

[Anonymous]

Not necessarily, because alerts are not for score changes.  Alerts are for CR changes.

For example, someone could have a very old account that's (say) 15 years old drop off their report and perhaps their next oldest account is only 7 years old.  The reduction to AoOA and AAoA if this file is relatively thin could be huge and cause a large score drop.  An old account falling off of a CR though is not an alertable event, so one may not realize that it even happened.

The weird part is that the Fico8 has no hit at all and the Fico9 bounces back within 30 days.
