Nasdaq says it is investigating how wildly inaccurate share-price information for a range of major US tech stocks went live on large consumer information services, including Bloomberg’s trading platform as well as Google Finance and Yahoo Finance.
Headline price figures for Amazon and for Google's parent company, Alphabet, were displaying as down by more than 80% as a result of the error, which emerged after US markets closed.
Share prices for Amazon, Alphabet, Apple, and Microsoft are all being returned as $123.47. Prices for about 16 stocks were affected.
A Nasdaq spokesman told Business Insider that the exchange's unlisted trading privileges service sent out some test data that was wrongly sent live on Bloomberg.
“As part of its normal process, the UTP distributed normal test data, and certain third parties improperly consumed and propagated that data," the spokesman said. "Nasdaq is working with UTP and third parties to resolve the matter."
Bloomberg has been contacted for comment.
Here are the (somewhat terrifying) screenshots. (To repeat: the prices are wrong!)
Google: being marked down 86%
Amazon: down 87%
Apple: relatively unscathed, down 14%
Microsoft: soaring almost 80%
Other listed companies including Facebook, Netflix, Atlassian, and Twitter appear unaffected.
