The New York Stock Exchange (NYSE) has completed an investigation into “irregular trading” after a series of unusual swings in some stocks.
The NYSE identified 140 stocks with higher-than-normal trading volumes, including popular stocks like Citigroup and American Airlines.
But they cancelled trades on only six stocks.
The moves brought back memories of the “flash crash” of 2010, when the Dow Jones index fell 10% in just minutes.
“The NYSE and NYSE MKT are currently reviewing irregular trading identified by our people and systems” in 140 stocks between 9:30 am EST and 10:15 EST on Wednesday, the exchange said initially.
