The far bigger problem is the loss of less-well known but wicked smart people like Mark Coatney and Arlyn Gajilian (who used to work for me here, so I can personally attest that its a loss).
Mark Hulbert, well-known for his performance-tracking newsletter The Hulbert Financial Digest, has been tracking it since 2002, and has reported of it more than doubling the performance of buy and hold over the long-term while taking only 61% of market risk.
