SPX: Standard and Poor’s 500® Index
The Standard & Poor’s 500 Index (SPX) is a capitalization-weighted index of 500 blue chip, large cap stocks from the U.S equities marketplace that represent a broad range of industry sector groups. It is a broad market index; together these 500 stocks represent approximately 75% of the U.S. equity markets. The impact of a price change in any component stock on the level of the overall index is proportional to the issue’s total market value. The S&P 500 has become the world’s leading benchmark for institutional investors, and so is widely quoted.
