Composed by Standard & Poor's, the S&P 500 index was introduced in 1923. It is a market-capitalization-weighted index that is associated with many ticker symbols, including GSPC, INX, and $SPX.

The S&P 500 index includes 500 components which are stocks of large companies traded at the New York Stock Exchange (NYSE) or the NASDAQ. The S&P 500 index reflects the overall capitalization rate of these stocks. The list of companies in the S&P 500 comprises only the biggest U.S. corporations and does not include private firms and companies with insufficient liquidity. In addition, the list of S&P 500 components represents various sectors of the U.S. economy.

The main trait of the index is its role in the world economy: the S&P 500 is well-diversified and perfectly mirrors the U.S. market state.
