Ein sehr kurioser Fall! United Airlines musste am 08.09. einen dramatischen Verfall seines Aktienkurses von 12 USD auf 3 USD beobachten, obwohl geschäftlich kein Grund vorlag. Doch es stellte sich im Verlauf des besagten Handelstages heraus, dass der Kapitalmarkt auf Basis einer 6 Jahre alten Meldung fehlgeleitet wurde, die über das Web gestreut wurde!! Wie das passieren konnte? LA Times:
UAL blamed the mess on a posting of a 2002 Chicago Tribune article on the South Florida Sun-Sentinel’s website. The story then was picked up by Income Securities Advisors, a Florida investment newsletter, and disseminated as a one-line brief over Bloomberg News — triggering a wave of panic selling. Tribune Co., the owner of the Sun-Sentinel (and also the parent of The Times), initially pointed a finger at Google Inc., saying it appeared that the search engine highlighted the story out of the Sun-Sentinel’s archives over the weekend, which generated traffic and caused the newspaper’s computer to move the story to a page of most-viewed articles. But Google said the only reason its search engine „crawler“ bothered with the story was that it was listed on the Sun-Sentinel page of most-viewed stories — and with the weekend date on it, instead of the 2002 date. To the crawler, „it was a new item that said, ‚Hey, look here,‘ “ Google spokesman Gabriel Stricker said.
Merke, das Datum sollte egal bei welcher Information hinterlegt sein:) Und zwar das genaue Datum:))
