NEW YORK (CNN/Money) - Major stock markets will observe the second anniversary of the Sept. 11 terrorist attacks with four separate minutes of silence, but their trading sessions Thursday will begin and end at their regular times.
According to press releases posted on their Web sites, the New York Stock Exchange and the Nasdaq will observe minute-long moments of silence at 8:46 a.m., 9:03 a.m., 9:59 a.m., and 10:29 a.m. ET Thursday, coinciding with other commemorative events in New York. The timing of the moments of silence reflects the times when two planes hijacked by terrorists on Sept. 11 crashed into the two towers of the World Trade Center and the times when the two towers collapsed.
During the moments of silence, there will be no trading activity on the NYSE and the Nasdaq has urged its members to refrain from trading as well. The Nasdaq also will not hold its regular market open ceremony and its Nasdaq MarketSite screen in Times Square in Manhattan will broadcast the city's Sept. 11 commemoration ceremony at the World Trade Center from 8:30 a.m. ET through its close, scheduled for noon.
At the NYMEX, where metals and energy futures are traded, the same moments of silence will be observed. Trading in metals futures will begin on time, but trading of energy futures will have a delayed opening at 10:51 a.m. ET. Following the fourth moment of silence, trading at NYMEX and its COMEX division will remain closed for 21 minutes in memory of each of the members and former members of the two exchanges who died in the terrorist attacks.
