Technical problems forced a nearly four-hour halt of trading on the New York Stock Exchange Wednesday, rattling investors and traders unnerved by volatility in the financial markets, The Wall Street Journal reported.
The exchange said on Twitter the problem “is not the result of a cyber breach”.
The shutdown was isolated to specific trading platforms, and investors could still buy and sell NYSE-listed stocks on others, such as NYSE’s own Arca exchange.
The trading suspension came in the middle of a broad selloff in US stocks that was spurred by a deepening rout in China’s stock markets.
NYSE told floor traders the problem originated in a software update it installed Tuesday night, the report said.
