Le Nasdaq a ferme aujourd'hui plus de 3 heures a cause d'un probleme informatique.
Nasdaq resumed trading at around 3:25 p.m. EDT (1925 GMT), after a roughly 3-hour, 11-minute shutdown of trading in Apple, Google, Microsoft and more than 3,000 other U.S. companies. The shutdown was the longest in recent memory.
All traffic through Nasdaq stopped abruptly at 12:14:03 p.m. (1614 GMT). Trading in a single stock resumed at 3 p.m., and other stocks soon followed.
Nasdaq's own stock, which was up 0.8 percent before the halt, closed down 3.4 percent, after earlier trading down as much as 5.4 percent.
The exchange blamed a problem with distributing stock price quotes for the shutdown. A source familiar with the matter described the problem as a "data feed issue."
