S&P Changes U.S. Market Cap Guidelines

February 16, 2011 - Standard & Poor’s is updating the market cap guidelines for its U.S. indices. Effective today, the new guidelines are: S&P 500– $4 billion or greater S&P MidCap 400– $1 billion to $4.4 billion S&P SmallCap 600– $300 million to $1.4 billion. Standard & Poor’s felt that the new market cap ranges for its U.S. indices are appropriate, based on review of recent market activity, comments from index users and the current U.S. market cap distribution. The guidelines refer to a company’s total market capitalization, not its float-adjusted cap.
