A wave of erroneous market data appeared on several finance sites in early Asia hours on Tuesday, with Nasdaq-listed stocks such as Apple, Google, Amazon and Microsoft all showing prices of $123.47 (S$171) each.
The incorrect data was discovered on Google Finance and Yahoo Finance.
Bloomberg terminals were also showing incorrect data, according to a Dow Jones report.
A Nasdaq spokesman told CNBC that the glitch came about after some test results were wrongly distributed to the third party finance sites.
"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," the spokesman said.
Bloomberg, Yahoo and Google did not immediately respond to CNBC's request for comment.
