Mayfield's Economics Blog: NASDAQ 100: Rebalancing

Nasdaq OMX is rebalancing the Nasdaq-100 index (QQQs), which currently has one company — Apple (AAPL) as more than 20% of the index.

The WSJ notes “Apple’s market capitalization is roughly $300 billion, twice that of Google. But its weighting in the index was five times that of Google. After the rebalancing, Google’s share of the index will be 5.8% compared to Apple’s 12.3%. Apple will remain the largest component of the index.”
