"Nasdaq Triggers Market-Wide Circuit-Breaker As AMZN [Amazon] "Crashes" 87% After-Hours... Nasdaq has issued a market-wide trading halt amid what appears to be a "glitch" that sent a number of the largest Nasdaq-listed stocks to crash or spike to exactly $123.47 per share... In a statement, Nasdaq said the glitch was related to 'improper use of test data' sent out to third party data providers, and said it was working to 'ensure a prompt resolution of this matter.'

Dunno yet Who knows what the third party data providers were trying to do with the "test data" that triggered this? But Yes -- most likely an instance of "moronware." Human error -- the omnipresent vulnerability.
UPDATE: "Finance sites erroneously show Amazon, Apple, other stocks crashing Test data from Nasdaq apparently mistakenly put onto live sites No, Amazon and Apple stock did not crash Monday. And if you held Mattel stock, you’re not suddenly rich. But incorrect stock data on the popular Google Finance, Yahoo Finance and Bloomberg sites appeared to be freaking out some investors Monday evening, after test data was apparently misinterpreted by third-party providers to those sites..." http://www.marketwatch.com/story/fi...amazon-apple-other-stocks-crashing-2017-07-03
