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 hours�with 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 result? A more accurate reading of market trends.
The "Last Sale" reflected on the NASDAQ-100 Pre-Market Indicator^SM 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.
