Mini-NDX Index Options (MNX) is 1/10th of the value of the NASDAQ-100® Index (NDX). The NASDAQ-100 Index is a modified market capitalization-weighted index composed of 100 of the largest non-financial securities listed on the Nasdaq Stock Market.

The value of the Index equals the aggregate value of the Index share weights, also known as the Index Shares, of each of the Index Securities multiplied by each such security’s Last Sale Price on Nasdaq (which may be the Nasdaq Official Closing Price), and divided by the divisor of the Index. If trading in an Index Security is halted on its primary listing market, the most recent Last Sale Price for that security is used for all index computations until trading on such market resumes. Likewise, the most recent Last Sale Price is used if trading in a security is halted on Nasdaq before the market is open. Nasdaq calculates and disseminates the NASDAQ-100® Index once per second from 09:30:01 to 17:16:00 ET. The closing value of the Index may change up until 17:15:00 ET due to corrections to the Last Sale Price of the Index Securities. The Index began on January 31, 1985 at a base value of 125.00, as adjusted.
