Amazon, Google parent Alphabet and two other companies saw trading on their stocks halted Wednesday, leading to a momentary WTF.

The New York Stock Exchange sent out an update that trading had been suspended for the day for Amazon, Alphabet, Booking.com and Zion Oil and Gas. There's nothing wrong with the companies. The NYSE points to a "price scale code issue" affecting trades. That's financial jargon for a trading bug that resulted in the exchange shutting down action for the day. 

A representative for the NYSE confirmed there is nothing wrong with the companies themselves. 

The halt comes during a busy earnings week, with Alphabet posting a profit and sales boost Monday and Amazon set to reported its quarterly results Thursday.
