S&P 100

In 1983, the CBOE created the first index options, based on its own index, the CBOE 100. In 1993, CBOE created the Chicago Board Options Exchange Market Volatility Index (VIX), which was computed based on the price of S&P 100 options (at the time these were by far the most heavily traded index options). Then in 2003, they changed it to be based on the S&P 500. == Record values ==

The mean free float market capitalization of the S&P 100 is over 3 times that of the S&P 500 ($135 bn vs $40 bn as of January 2017); as such, it is larger than a large-cap index. The "sigma" of companies within the S&P 100 is typically less than that of the S&P 500 and thus the corresponding volatility of the S&P 100 is lower. However, the correlation between the two indices is very high. ==Investing==

This index is tracked by the exchange-traded fund iShares S&P 100 Index (). == Annual returns ==
