Meilleur commentaire critique
highly interesting but some modesty might be necessary
le 13 octobre 2009
this book is a good introduction to a fractal approach of financial markets, it introduces the concepts of dependent path, the non-efficiency of markets, it critises a "too brutal" approach of the CAPM, or other efficient market based theories.
BUT I have some regrets because the author is not what I would call modest (although he deserves more than some merits for the findings, ideas...) but enough is enough and lauding oneself adds few value to the content. In addition and more criticable is that a generous first half of the book is dedicated to basic explanations of what are the efficient market theories and why they are wrong. It turns out that it is more a conceptual critic of the standards theories than the explanation of the fractal theories and "how to implement". I regret a bit that the book is not really dedicated to the subject announced in the title, or at least not what I expected from it.
This said this is an inresting book that will fit well in your financial library and will surely enrich your knowledge.
