Amazon and Google share prices were wrongly reported down more than 80% after test data went live


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 services as well as Google Finance and Yahoo Finance.

Headline price figures for Amazon and Google’s parent company, Alphabet, were displaying as down more than 80% as a result of the error, which emerged after US markets closed.

Share prices for Amazon, Google’s parent company Alphabet, Apple, and Microsoft are all being returned as $123.47. Prices for around 16 stocks were affected.

A Nasdaq spokesman told Business Insider that its unlisted trading privileges (UTP) service sent out some test data which 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. Nasdaq is working with UTP and third parties to resolve the matter,” the spokesman said.

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.
