Glitch Briefly Shows Incorrect U.S. Tech Stock Prices

   By Steven Russolillo

A flood of incorrect stock-market data briefly hit traders' screens around the globe early Tuesday morning in Asia, showing wide fluctuations in shares of some of the world's biggest companies.

Nasdaq-listed securities were the victims as Apple Inc. showed a loss of 14%, Amazon.com Inc. was shown as being off 87% and Microsoft Corp. was up 79%. The prices of all three were indicated at $123.47. The apparent glitch spread across pages on Yahoo Finance and Google Finance as well as on Bloomberg terminals.

A Bloomberg spokesperson said inquiries should be directed to the Nasdaq Stock Market. A Nasdaq spokesman said: "As part of its normal process, the [unlisted trading privileges] distributed test data and certain third parties improperly propagated the data. Nasdaq is working with third party vendors to resolve the matter."

A system status message posted on Nasdaq's website said "systems are operating normally."

As of 9:20 am Hong Kong time, the issue appeared to have been fixed across Google Finance and Yahoo Finance pages.
