“Markets aren’t supposed to work this way,” said Jamie Selway, managing director of White Cap Trading LLC in New York and a former chief economist at NYSE Arca, a unit of NYSE Euronext. “There was a mad rush for the exits. We just don’t know whether it was accidental or intentional.”
Computer programs that increase sell orders when stocks are falling may have exacerbated yesterday’s plunge, said Nick Colas, chief market strategist at BNY ConvergEx Group LLC in New York. Programs that may have smoothed out trading during periods of low volatility can “make market moves a lot worse” when equities are plunging, he said.
“This was like what we saw happen on the worst days of the financial crisis in late 2008 and early 2009,” Colas said. “This is not a healthy dynamic. The markets need to work efficiently and properly, particularly during periods of stress.”
