McGraw-Hill Financial's (NYSE: MHFI ) 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 (NYSE: GM ) . The stock replaces Heinz (NYSE: HNZ ) , which was recently acquired by a consortium led by Berkshire Hathaway (NYSE: BRK-B ) .
Also taking a slot on the S&P 100 will be insurance giant AIG (NYSE: AIG ) , taking the position currently held by Baker Hughes (NYSE: BHI ) . 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.
