Computer glitch lists several Nasdaq tech stocks at same price

Posted July 05, 2017

Share prices for Apple, Google parent company Alphabet, Amazon, and Microsoft all appeared at $123.47, which would've marked a whopping crash if it were true.

Many Nasdaq-listed share prices were displayed incorrectly, to exactly $123.47 or thereabouts, on stock price resources such as Google and Yahoo Finance, and Bloomberg terminals.

Google's website says Swiss-based SIX Financial Information provides end-of-day prices, and New York-based Interactive Data Real-Time Services provides intra-day prices. But yesterday a data glitch resulted in the Nasdaq reporting incorrect share prices for many high profile U.S. tech stocks. Nasdaq is working with UTP and third parties to resolve the matter.

Apple (AAPL) shares rose 348% to $645.71 in late trading Monday, according to dubious data appearing on Yahoo Finance. An 87% plunge in Amazon stock would have wiped almost $400 billion off the company's market capitalization.

Nasdaq, the world's second largest stock exchange, said in a statement it was investigating the improper use of test data distributed by third parties.

The problem lay behind routine test data sent out by United States exchanges including Nasdaq (NASDAQ:NDAQ), which was taken to be live figures. Despite sporadic claims of some trades being made at the $123.47 price, Nasdaq told the FT that it did not affect market trading.

A spokesman for Nasdaq put the blame on third-party data providers.

The NASDAQ's own website did not display any irregularities, and a system status message showed that the system was operating normally. It appears that market trading was not affected, including pre-market trading.
