New York Stock Exchange ( NYX) fell again Tuesday as the exchange edged ever closer to its imminent $14 billion merger with Europe's Euronext exchange. Shares were losing $2.63, or 2.6%, to $94.37.

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

The analyst, however, says Nelnet is likely to gain market share from the Federal Family Education Loan Program business. Shares were up $1.17, or 4.3%, to $27.82.

Medical Properties Trust ( MPW) continued to rise after an analyst with Robert W. Baird began his coverage on the real estate investment trust late last week with a buy rating. The REIT specializes in investing in health care facilities. Shares were climbing 25 cents, or 1.7%, to $15.06.

State Bancorp ( STBC) was still rising after Friday's announcement that the New York bank had raised more than $36 million in a 2.3 million share private placement. 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. Late last week the property management company said the underwriters were buying an additional 1.9 million of its shares at a price of $38 apiece. Shares were down 9 cents to $38.20.
