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.
