From the FT: stock in Berkshire Hathaway, Warren Buffet’s company, jumps every time Anne Hathaway, the actress, gets a lot of media play.Really? Am I the only one who is astonished that Market Gods are robots that can't tell the difference between Ann Hathaway and Berkshire Hathaway and obviously just buy and sell on "buzz" whether it's good or bad? That's not even remotely rational.Why? The claim is that it’s the fault of robotrading algorithms, which now account for most of the market, and which sometimes rely among other things on trends in news coverage.
