NYSE Arca has suspended trading in eight symbols for the balance of the trading day due to a technical issue, including Amazon.com and both classes of Alphabet Inc shares, according to an alert from the exchange.
The alert stated all orders have been canceled back to customers and a spokeswoman for the exchange confirmed it was not an April Fool's Day prank.
The NYSE recently rolled out a new trading platform, called "Pillar" on Feb. 1, but it was not known if issues with the new platform had spurred the trading suspension.
Other affected stocks included AutoZone Inc and Intuitive Surgical.
Joe Christinat, a spokesman for Nasdaq, said "all our systems are operating normally" and the stocks could be traded at Nasdaq regardless of issues at another exchange.
