(NEW YORK) — A technical problem shut down operations in the Nasdaq for nearly three hours Thursday before trading returned to normal.
“This is not something that I think we have ever seen,” said Art Hogan of Lazard Capital Markets. “There will be times when exchanges will have to halt for a short period of time [but we’ve] never seen such a large shutdown.”
The glitch affected the stock exchange’s electronic system that links 13 exchanges as well as connects bids and offers, Hogan said. The Nasdaq had to request that trading of its stocks be stopped.
The move hit many companies that most Americans hold in their retirement savings — Google, Apple, Microsoft and Facebook.
Fortunately, when the stock exchange resumed, it closed higher, so while it created a lot of anxiety, it did not hurt savings. The New York Stock Exchange remained open.
“The only silver lining is that it is a slow day,” said Jonathan Caropina of Meridian Equity Partners. “But that is not much of a silver lining. … The bigger issue here is that once again we have a technology fault that is impacting investors big and small. Markets have become too fragmented and too mechanical.”
Law enforcement officials told ABC News that the glitch was not a hack attack or caused by an outside influence.
FBI Director Robert Mueller, however, said that one of the main things that kept him up at night were cyber-threats to U.S. financial markets.
President Obama was briefed Thursday on the shutdown and the Securities and Exchange Commission, the FBI and the Treasury Department are investigating the incident.
“If it were another day, a busier day maybe, we would have had a more significant impact,” Hogan said. “It’s still certainly concerning.”
