Google Trends and Mr. Market, from Rocky Humbert
The google trend for "Nouriel Roubini" peaked just as the economy and markets bottomed. I don't think this was a coincidence.
In the short-term, Mr. Market is a voting machine. And google searches reflect those votes. It provides a coincident snapshot of the first and second derivatives of votes. Whether it leads or lags, market prices are an exercise left to the reader.
In the long-term, Mr. Market is a weighing machine. And all of this stuff is noise. And in the really long term, we are all dead.
