NASDAQ OMX said Tuesday it would rebalance its NASDAQ-100 stock index to reduce Apple's weight on the market. As of May 2, AAPL will move from its large 20.5 percent of the index to 12.3 percent while other companies will get more influence, including Google (5.8 percent), Intel (4.2 percent), Microsoft (8.3 percent), and Oracle (6.7 percent). The aim is to give Apple a ratio relative to its size and not simply the number of shares.
