Updated every sixty seconds after the official 4:00 p.m. Eastern Time (ET) close of the market, The Nasdaq After-Hours IndicatorSM calculates the last sale prices of the Nasdaq-100® stocks during after-market trading, 4:00 p.m. - 6:30 p.m. For those securities that did not trade in the after-market, prices are calculated using the last sales price from that day’s 4:00 p.m., (ET) closing. It can also be seen on the Nasdaq MarketSiteSM multi-media wall in Times Square.
The Pre-Market IndicatorSM, which tracks stock movement of the Nasdaq-100 stocks in the 8:15 a.m. to 9:30 a.m., (ET), pre-market hours, has become a widely used instrument to gauge investor sentiment prior to the official Nasdaq market open at 9:30 a.m.
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. The Pre-Market and After-Hours indicators aim to take this one step further. Tracking over several months has shown that the Nasdaq-100 Pre-Market Indicator and After-Hours Indicator are on target in assessing market sentiment leading up to the 9:30 a.m. open and in after-hours trading. The uniqueness of the PMI and AHI is in the advanced, patent-pending filtering/edit checking that is done to filter out erroneous trade reports. This allows for indicators that have a nearly 1 to 1 correlation with the Nasdaq-100 Index
"Historically, information on market sentiment during extended trading has been primarily limited to observation of activity in individual stocks or futures contracts," said Don Bosic, Senior Vice President, Nasdaq Interactive Services. "Now, with the Pre-Market and After-Hours Indicators, it’s possible to get a bigger and more accurate picture based on actual trading data. Since its introduction last October, the Nasdaq-100 Pre-Market Indicator is the fastest growing area of our Web site."
