Shares of McGraw-Hill (MHP) climbed more than 6% Thursday morning after Bloomberg said the company could be worth 40% more if it were to split into pieces.

The report, which cited research by J.P. Morgan (JPM), showed the owner of Standard & Poors could get as much as $5 billion extra for shareholders just by separating certain businesses.

Shares of the company, whose S&P business has been the target of much criticism over the last several weeks after an unprecedented downgrade of the U.S. economy, are still down 7% for the month.

Standard & Poors said it will replace current its current president Deven Sharma with Citibank (C) chief operating officer Douglas Peterson when he resigns at the end of the year.
