The 300 Club - Death Of Common Sense - April 2012 "The 2008 market crash was the outcome of a complex set of factors. One of them was modern portfolio theory which fostered the belief that markets are always right and mean reversion towards fundamental values is the norm. This faulty thinking had profound impact on investor psyche and policy thinking. Its time to develop fresh thinking on how markets really work and highlight the issues that really matter to today's investors."
