The NASDAQ 100 index is a composite weighted index based on market capitalization with a number of different rules that govern the degree to which the larger stocks in the index influence it.

The stock is very heavily weighted with technology and biomedical stocks, although it does not contain any financial business stocks, unlike the S&P500. Corresponding futures for the index are traded on the Chicago Mercantile Exchange as both regular futures, and the newer e-mini style.
