Apple Inc (NASDAQ:APPL) and Amazon Inc. (NASDAQ:AMZN) shares seemingly plunged yesterday on Google Finance and Yahoo Finance after third parties provided incorrect data.
Amazon’s shares were displayed as down 87% to US$123.47 on Google Finance and down 74% to US$248.29% on Yahoo Finance after Wall Street closed early for the 4 July break. But in fact the tech giant finished the day down 1.5% at US$953.66, according to Factset.
Similarly, Apple shares fell 14% to US$123.47 on both Google Finance and Yahoo Finance. In reality the iPhone maker fell just 0.4% to $143.50, FactSet said.
Google's parent company Alphabet (NASDAQ:GOOGL) fell 86.71% to US$123.47 . In contrast, Mircrosoft Corporation (NASDAQ:MSFT) soared 80%, giving the company a valuation of more than US$1trn.
A spokesman for Nasdaq said the exchange operator was conducting a test of its pricing data feed, which was mistakenly distributed to Google Finance and Yahoo Finance by third party providers. No trades were affected by the flawed quotes.
Google’s end-of-day prices are provided by Swiss-based SIX Financial Information while the intra-day prices are provided by New York-based Interactive Data Real-Time Services, Inc.
Google and Interactive Data Real-Time Services’ parent company, Intercontinental Exchange, did not immediately respond for comment. A SIX spokesman to;d MarketWatch his company wasn’t at fault.
“We checked with our data team — our data is correct and in no way corrupted,” the SIX spokesman said in an email.
