Q&A for Extended Trading
What is the Nasdaq-100 Pre-Market IndicatorSM?
A question asked every day by investors and the financial news media is “Will the market open up or down today?” The Nasdaq-100 Pre-Market Indicator is an index of trading activity based on pre-market open prices. The PMI was developed by nasdaq.com to help gauge pre-market trends leading into the trading day as a predictor of opening prices.
What is the Nasdaq-100 After Hours IndicatorSM?
The Nasdaq-100 After Hours Indicator is also an index of trading activity. The AHI is based on extended trading prices during the after hours market, 4:00 to 6:30 p.m. ET.
How would the Nasdaq-100 Indicators be used?
Historically, limited information sources have been available to gauge market sentiment during extended trading, leading into or after regular market hours trading. Resources have been pretty much limited to observation of trading activity in individual stocks or futures contracts.
Now, with the PMI and AHI, it’s possible to get a big pre-market or after hours market picture based on actual trading data.
How representative of the market as a whole are the Nasdaq-100 Indicators?
The Nasdaq-100 Index has, since its inception, been one of the most frequently used gauges of the marketplace and is widely considered to be a good barometer of the market as a whole. With the same calculation as the Nasdaq-100 Index but using pre-market or after hours prices, the Nasdaq-100 Indicators offer a helpful measure — indicating extended trading trends.
How are the Nasdaq-100 Pre-Market and After Hours Indicators calculated?
The Indicators are minute by minute calculations during extended hours trading, using the same calculation used for the Nasdaq-100 Index during regular market hours.
- The Pre-Market Indicator is calculated based on last sale prices of Nasdaq-100 securities during pre-market trading, 8:00 to 9:30 a.m. ET. If a Nasdaq-100 security does not trade during the pre-market, the calculation uses last sale from the previous day 4 p.m. closing price.
- The After Hours Indicator is calculated based on last sale prices 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.
How was the quality of the Nasdaq-100 Pre-Market and After Hours Indicators evaluated?
Nasdaq Economic Research performed an analysis of the methodology for calculating the Indicators’ values and determined that the methodology is consistent with calculation of the Nasdaq-100 Index during regular market hours and has shown good continuity with prices at open and close of regular market hours.
