I too am curious. But then this reminds me of my days at Interactive Data and their use of data from the S&P pricing service and then their purchase of the service. Checking the data for accuracy was always a concern.

The other interesting question is what the effects are in a market that trades on millisecond events. It’s like turning your computer clock ahead and finding out all sorts of events had fired and you couldn’t simply turn the clock back. How many events outside of the NASDAQ purview were triggered?

Airlines Stock to Plummet -- UPDATE Google Placed Wrong Date on Story

Dave, With respect to the United story, the last few minutes of NASDAQ
had an amazing event relating to Google stock that is not reported in
today's NYT and mentioned only in passing in a very brief detail-free
summary in the San Fran Chron.

  GOOG: Stock Quote & Summary Data   had this GOODy.

  Last Sale  $320.50
  Change Net $60.50  -15.89%
  Today's High/Low $483.63 / $39   [NOT A TYPO]

In a glitch that apparently remains to be explained,
the stock price took a horrendous dive in the last
few minutes and then recovered.  Although some people
tried to profit from it, NASDAQ apparently revoked all
transactions that occurred during the downward "surge".

TheAustralian.news.com.au blames "Erroneous trades" routed
to Nasdaq sent Google shares tumbling.  Shares rebounded
in after-hours trading to $413.06.

I look forward to some detailed explanations for RISKS.

Peter
