Nelnet ( NNI) rose after an analyst with J.P. Morgan Chase reiterated his overweight rating on the student lender.

Shares were up 41 cents, or 2.1%, to $19.76. Brookfield Properties ( BPO) slipped again following the news that the underwriters of its recent $1.14 billion stock offering have exercised their over-allotment option.
