An apparent glitch at the operator of the New York Stock Exchange triggered volatility trading halts shortly after the open in about a dozen companies, including Chipotle Mexican Grill Inc. and Abbott Laboratories.
NYSE said it was having issues pertaining to the limit up-limit down trading bands, which typically govern when stocks are paused for volatility. The sudden disruptions come just days after a glitch last week left the S&P 500 Index without live pricing for an hour, and as the market adapts to quicker settlement times for US stock trades.
