S&P 500 Index

The S&P 500 Index is a free-float capitalization-weighted index, which includes 500 large-cap common stocks traded actively in the United States.

The S&P 500 index, also known as S&P 500, SP500 or Standard & Poor's 500 index, includes 500 large-cap common public stocks actively traded in the U.S. stock exchanges. After the Dow Jones Industrial Average, the S&P 500 index is the most widely followed index of large-cap U.S. stocks, capturing 75% coverage of U.S. equities. It is considered a bellwether for the American economy, as it is includes both growth stocks and the generally less volatile value stocks.

Calculation Of Index

The S&P 500 index has traditionally been market-value weighted, meaning, movements in the prices of stocks with higher market capitalizations have a greater effect on the index than companies with smaller market caps. Since 2005 the S&P 500 index is float weighted. That is, Standard & Poor's now calculates the market caps relevant to the index using only the number of "float" shares, which are available for public trading.

Selection Of Index Components

The S&P 500 index is focused on U.S.-based publicly traded companies, although there are a few legacy companies with headquarters in other countries. The stocks included in the S&P 500 are those of large publicly held companies that trade on either of the two largest American stock market companies; the NYSE Euronext and the NASDAQ OMX. The components of the S&P 500 index are selected by committee, so they are representative of the industries in the United States economy.
