NYSE Arca Glitch Impacted ETF Trades

NYSE Group sowed confusion among traders after a technical error hobbled one of its exchanges on Monday.

NYSE Arca, the largest U.S. listing venue for exchange-traded funds, shifted to backup methods for calculating the closing prices for most securities, according to a series of trader alerts. The exchange closed early for its after-hours session, saying it wouldn’t resume trading until 4 a.m. New York time on Tuesday. Kristen Kaus, a spokeswoman for NYSE, declined to comment beyond the trader alerts.
