Fake Doc Alan Greenspan, from Victor Niederhoffer
Fake doc Alan Greenspan's tenure at Fed began August 11th, 1987, with S&P at 330. On December 30th, 1987, market was 240. Paul Vollker's tenure began August 6th, 1979, with S&P at 1014. It closed the year at 1010. Janet Yellen saw a rise in S&P when her tenure began in Feb 2014. It seems that there is a tendency to test the new Fed chair as he begins his tenure.
Chair Bernanke's term which began on February 1st, 2006, the market only dropped 3% during the next few months. The point being that the market likes to test the new Fed chair to see if he will be bullish.
