Because of rising loan amounts and interest rates, a worrisome trend has emerged: Loans where the borrower can make only partial payments or has gotten a delay are up to 6.4% from 4.7% a year ago. (Borrowers start repaying after graduation.) Meanwhile, Sallie Mae has suffered earnings reversals, mainly from fumbled derivatives, which have pulled the stock down a tad.
