Widely regarded as the best single gauge of the U.S. equities market, this world-renowned
index includes 500 leading companies in leading industries of the U.S. economy. Although the
S&P 500 focuses on the large cap segment of the market, with approximately 75% coverage of
U.S. equities, it is also an ideal proxy for the total market. S&P 500 is part of a series of S&P
U.S. indices that can be used as building blocks for portfolio construction.
S&P 500 is maintained by the S&P Index Committee, a team
of Standard & Poor’s economists and index analysts, who
meet on a regular basis. The goal of the Index Committee
is to ensure that the S&P 500 remains a leading indicator of
U.S. equities, reflecting the risk and return characteristics
of the broader large cap universe on an on-going basis. The
Index Committee also monitors constituent liquidity to ensure
efficient portfolio trading while keeping index turnover to a
minimum.
The S&P Index Committee follows a set of published
guidelines for maintaining the index. Complete details of
these guidelines, including the criteria for index additions
and removals, policy statements, and research papers are
available on the Web site at www.indices.standardandpoors.
com. These guidelines provide the transparency required and
fairness needed to enable investors to replicate the index and
achieve the same performance as the S&P 500.
Criteria for Index Additions
- U.S. Company. Determining factors include location of the
company’s operations, its corporate structure, its accounting
standards and its exchange listings.

excess of US$ 3 billion. This minimum is reviewed from
time to time to ensure consistency with market conditions.

quarters of positive as-reported earnings, where as-reported
earnings are defi ned as GAAP Net Income excluding

annual dollar value traded to market capitalization for the
company should be 0.30 or greater. Very low stock prices
can affect a stock’s liquidity.

line with the sector composition of the universe of eligible

Closed-end funds, holding companies, partnerships,
investment vehicles and royalty trusts are not eligible.

Continued index membership is not necessarily subject to
these guidelines. The Index Committee strives to minimize
unnecessary turnover in index membership and each removal
is determined on a case-by-case basis.
Criteria for Index Removals
- Companies that substantially violate one or more of the
criteria for index inclusion.
- Companies involved in merger, acquisition, or signifi cant
