NASDAQ 100 index

NASDAQ is an abbreviation for the National Association of Securities Dealers Automated Quotation system. It is also commonly, and confusingly, called the OTC market.

The Nasdaq-100 Pre-Market Indicator and the Nasdaq-100 After Hours Indicator are based on the same calculation used by the Nasdaq-100 Index during regular market hourswith key differences:

The Pre-Market Indicator is calculated based on last sale of Nasdaq-100 securities during pre-market trading, 8:00 to 9:30 a.m. ET. And if a Nasdaq-100 security does not trade in the pre-market, the calculation uses last sale from the previous day's 4 p.m. closing price. The After Hours Indicator is calculated based on last sale of Nasdaq-100 securities during after hours trading, 4:00 to 6:30 p.m. ET. And if a Nasdaq-100 security does not trade in the after hours market, the calculation uses last sale price from that day's 4 p.m. closing. Both indicators use unique editing logic that filters any bad trades from the calculation.

The "Last Sale" reflected on the NASDAQ-100 Pre-Market IndicatorSM page is the NASDAQ Official Close Price (NOCP). Tracking over several months has shown that the Nasdaq-100 Pre-Market Indicator and After Hours Indicator are on target as gauges of market sentiment leading up to the 9:30 a.m. open and in after hours trading. The Nasdaq-100 Indicators are a meaningful tool for investors and the financial news media who want to get a sense of the market during extended trading hours.

In recent years interest in the Nasdaq-100 Index has grown tremendously, as evidenced by the increased trading volume in options and exchange-traded funds (ETFs) related to the index.

The Nasdaq-100 Index, launched in January 1985, represents the largest and most active non-financial domestic and international issues listed on The Nasdaq Stock Market based on market capitalization. The index is calculated under a modified capitalization-weighted methodology.

Nasdaq-100 Index Options. Trading in cash-settled options on the Nasdaq-100 (NDX) index began on the CBOE on February 7, 1994. Nasdaq-100 Index Tracking Stock represents ownership in the Nasdaq-100 Trust, a long-term unit investment trust established to accumulate and hold a portfolio of the equity securities that comprise the Nasdaq-100 Index. Its initial market value approximates 1/40 the value of the underlying Nasdaq-100 Index.
