Software Update Could Have Caused NYSE Trading Halt

$ICE

A computer malfunction that forced the New York Stock Exchange to suspend trading for 3.5 hrs Wednesday likely was caused by a software update that went off,

The New York Stock Exchange, a unit of Intercontinental Exchange Inc (NYSE:ICE), reopened at 3:10p EDT (1910 GMT) after trading was halted shortly after 11:30a EDT. NYSE said the outage was due to an internal technical issue and not the result of a cyberattack. Other exchanges were trading normally.

The NYSE must now verify the cause and report its conclusions to the US Securities and Exchange Commission (SEC), which will use those findings to investigate whether any violation of rules occurred.

A NYSE spokeswoman said the root cause of the trading halt was determined to be a “configuration issue.”

“Trading of NYSE-listed stocks continued on NYSE Arca and other US trading venues throughout this process,” she said.

Still some media pundits have raised the specter of a cyberattach based on all of the malfunctions Wednesday and recently nationwide.
