The Journal of Financial Planning recommended and linked to (SFI Trustee) Michael Mauboussin's recent paper for being among the better practitioner-oriented research papers. “Fat Tails and Nonlinearity” (Michael Mauboussin, Legg Mason, December 20, 2007, http://www.leggmason.com/individualinvestors/documents/insights/D4114-FatTailsNonlinearityLMIS.pdf). (... this (is an ) excellent non-journal article. Bringing Nassim Taleb’s now well-known black swan metaphor to the worlds of investment planning, Mauboussin introduces the reader to the concept and risk associated with the complex system we call “the market.”
