NASDAQ Financial -100 Index was introduced on the same day as Nasdaq100. This explains why the financial companies were and still are excluded from the Nasdaq100 index.The usual abbreviation for Nasdaq100 is NDX and the NQ is the abbreviation for the e-mini indexes.To be included in the Nasdaq100 index a security must meet many criteria such as, it must be of a non-financial company, must not be part of a bankruptcy proceedings, only one class of security per issuer is allowed and many more.
