(Reuters) – Trading in thousands of U.S. stocks ground to a halt for much of Thursday after an unexplained technological problem shut down trading in Nasdaq securities, the latest prominent disruption to the operations of U.S. markets.
…It [Nasdaq's parent Nasdaq OMX Group Inc] said a “connectivity issue” between an unnamed exchange participant and the SIP caused the breakdown, and that the cause has been “identified and addressed.”
Thursday’s outage was the latest high-profile glitch in U.S. stock markets.
On Tuesday, a technical problem at Goldman Sachs Group Inc resulted in a flood of erroneous orders in U.S. equity options markets.
Two weeks earlier, on August 6, stock exchange operator BATS Global Markets faced a nearly hour-long outage.
