In the famous simile of the cave, Plato compares men to prisoners in a cave who are bound and can look in only one direction. They have a fire behind them and see on a wall the shadows of themselves and of objects behind them. Since they see nothing but the shadows, they regard those shadows as real and are not aware of the objects. Finally one of the prisoners escapes and comes from the cave into the light of the sun. For the first time, he sees real things and realizes that he had been deceived hitherto by the shadows. For the first time, he knows the truth and thinks only with sorrow of his long life in the darkness. -- Werner Heisenberg, Physics and PhilosophyLast year's surprise list had relatively poor results. Only about 40% of my surprises were achieved in 2010, well under the success ratio in previous years. By means of background, about 50% of my 2009 surprises were realized, 60% in 2008, 50% in 2007, one-third in 2006 , one-fifth in 2005, 45% in 2004 and one-third came to pass in the first year of our surprises in 2003. While my surprise list for 2010 hit on some of the important themes that dominated the investment and economic landscape this year, I failed to expect the announcement of further quantitative easing and did not accurately gauge investors' animal spirits that followed the proclamation of QE2.
