The New York Stock Exchange midday Wednesday suspended trading in the shares of five Nasdaq-listed companies including Google-parent Alphabet and Amazon due to a what it referred to as “a price scale code’ issue. NYSE made the announcement around 11 a.m. Eastern Time, according to its website. The companies include Amazon.com Inc. , shares of Google-parent Alphabet Inc. and , as well as Zion Oil & Gas Inc. . All of the stocks, except those for Zion Oil & Gas Inc., trade at prices over a $1,000, but details on the trading halt weren’t made clear. NYSE didn’t immediately return a call for comment. Because these securities trade on multiple exchanges a halt on one exchange isn’t expected to cause problems in trading. Shares of Alphabet Inc. shares were up 0.7%, while Amazon’s shares were off 4.1%, Zion’s shares were up about 0.5%, those for Booking Holdings Inc. (formerly known as Priceline Group) were up 0.7%. The glitch comes as the Dow Jones Industrial Average is under some pressure, down 0.1% at 24,003, and trying to avoid a fifth day of losses in a row, while the S&P 500 index was trading flat, and the Nasdaq Composite Index was little changed on the day. A report from the Wall Street Journal indicates that Wednesday’s trading snafu comes a few weeks a recent tech upgrade and after NYSE “opened its doors to trading of stocks and exchange-traded funds listed on other exchanges.” The NYSE, also known as the Big Board, is owned by Intercontinental Exchange Inc. .
