OEX: Standard and Poor’s 100®Index
The Standard & Poor's 100 Index (OEX) is a capitalization-weighted index of 100 blue chip, large cap stocks from the U.S equities marketplace from diverse industry sector groups. It is a broad market index; together these 100 stocks represent over 50% of the market capitalization of the S&P 500® Index. 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. Options on the S&P 100 are used primarily by hedgers and speculators in conjunction with bullish or bearish opinions on large-cap U.S. stocks.
