Data glitch: Google, Yahoo finance sites display incorrect stock market prices

“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.

A Google spokesperson confirmed to CNBC that its third-party finance data provider was providing inaccurate information received from Nasdaq.

“This is currently being fixed and we hope to update our stock price data shortly,” she said.

Bloomberg and Yahoo did not immediately respond to CNBC’s request for comment.

Correction: This article has been corrected to reflect that Nasdaq indicated the incorrect data was distributed by third parties.
