McGraw-Hill Financial's S&P Dow Jones Indices has brought in a pair of big-name stocks to replace issues on two of its signature products. After the close of trading on June 6, both the S&P 100 and the 500 will be home to General Motors (GM -0.58%). The stock replaces Heinz (HNZ +0.00%), which was recently acquired by a consortium led by Berkshire Hathaway.

Also taking a slot on the S&P 100 will be insurance giant AIG (AIG +0.40%), taking the position currently held by Baker Hughes (BHI +0.00%). The latter's total market capitalization is now below $21 billion, which S&P Dow Jones Indices says "is no longer representative of the megacap market space." The stock will, however, remain on the S&P 500.
