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.
As of 11 p.m. Eastern, Google Finance said Amazon.com Inc. shares were down more than 87%, to $123.47. Previously, Yahoo Finance said Amazon was down 74%, to $248.49. In reality, Amazon AMZN, -1.48% finished the day down 1.5%, at $953.66, and was up 0.1% in after-hours trading, according to FactSet.
Apple Inc. shares were similarly skewed, with both Google and Yahoo Finance saying they were down 14%, also to $123.47. Actually, Apple AAPL, -0.36% ended the day down just 0.4%, at $143.50, according to FactSet, and was up slightly in after-hours trading.
$123.47 — or amounts close to that — appeared to be the common denominator for the test data, wildly skewing some stocks down to that level while others skyrocketed up to it. For example, the test data sent eBay Inc. EBAY, -0.92% soaring 253%, Mattel Inc. MAT, -2.51% skyrocketing 473% and Microsoft Corp. MSFT, -1.10% up 79%.
Page views to MarketWatch’s stock pages — which remained accurate — soared as investors double-checked exactly what was going on Monday evening.
A spokesman for Nasdaq put the blame on third-party data providers.
“As part of its normal process, the UTP distributed test data and certain third parties improperly propagated the data. Nasdaq is working with third-party vendors to resolve the matter,” a Nasdaq spokesman said late Monday.
The spokesman speculated that the day’s early close might have caused confusion with some closing prices for a number of third parties, including Bloomberg and Yahoo, but emphasized that no trades were affected by the erroneous quotes.
Yahoo Finance and Bloomberg appeared to be showing correct ticker data as of 11 p.m. Eastern, but Google Finance was still showing the test data.
Google’s website says Swiss-based SIX Financial Information provides end-of-day prices, and New York-based Interactive Data Real-Time Services, Inc. provides intra-day prices. Google, SIX Financial Information and Interactive Data Real-Time Services’ parent company, Intercontinental Exchange, did not immediately respond for comment.
