I suggest looking at both EQ FICO reports very closely. The shift from the postitive side to the negative, or vice-versa, can indicate one of a couple of things. It can indicate that something else changed on your report which pushed that once-positive factor into the negative side, which can include dropped accounts, added accounts, changes in utilization on your cards, added baddies, removed baddies, new inquiries, etc. FICO will look for the smallest things to complain about on your FICO report and maybe items that once were bad, are no longer bad and the length of history moved over to the negative side. Along those same lines, changes in your EQ report, like an older history, can also lead to rebucketing. This may or may not be the case for you as not every pos/neg factor change is the result of rebucketing, but if they're all scrambled then it could be that you were rebucketed.
