Thoroughly useless
|
|
This book looks like a sales pitch for someone getting into the consulting business. It is neither particularly insightful nor detailed, and is certainly not useful for portfolio construction and risk management. It lies well outside the mainstream practice and thinking within the industry, and serious alternatives are plentiful. Avoid.

Not for the asset allocation user (vs. creator)
|

I would agree with the comments of the first 2 reviewers. That is, the book is honest, concise and thorough in addressing the pitfalls of using Mean-Variance optimization techniques for finding optimum asset allocations (i.e., minimum risk for given expected return). However, if you don't do your own asset allocation calculations (i.e., process historical trends to find the "efficient frontier") the only value of the book is to make you aware of the issues around using Markowitz mean-variance techniques and, therefore, be questioning of any asset allocation models you come across. In other words, for the user (vs. creator) of asset allocation models be aware that if the creator wasn't careful in his statistical techniques the models could be wrong. Also, what I also got out of the book was, in many cases, rebalancing of a portfolio may not be needed as frequently as many suppose as the efficient frontier is more of a cloud then a line.

Raises important questions

Michaud raises several important issues that one is sure to encounter in portfolio optimization. Michaud exposes the fallibility of mean-variance optimization and suggests several techniques to obtain more reliable results. His conclusions merit consideration. Props for increasing the breadth of statistical scope of efficient asset management. Michaud is also a fluid writer. My largest complaint is that the majority of his work utilizes sign-constrained (long-only) optimization. If you manage, advise or consult on portfolio management and you utilize optimization techniques or have considered them, you should become knowledgeable with the contents of this book.

This short, simple book offers a synthesis of research about the uses and practical problems associated with Markowitz optimization procedures. It will give you a good opportunity to see in a few interesting hours what can go wrong in implementing MV optimization and what to do to improve the process. Things that are relatively obscure, but have a direct practical relevance, such as considering the efficient frontier as having a variance, and offering some pointers on where to get arcane Stein-like estimators for the variances and covariances (Ledoit estimators). There is no math entrance barrier (almost no equations), so this book will be of benefit to users of MV optimization who want to understand the issues deeper and not just press on a button and assume that the weights they get make sense. It is to be noticed that this is not the book for those interested in quadratic programming algorithms per se, as the focus is more from a user point of view. Also notice there are no new results in the book and that sometimes I wished some discussions were more detailed - but they may be too detailed for some other readers as well. In brief an honest book, not too dumb and not too hard. An interesting and useful reading for all users of MV optimization. Also, a perfect book to complement an undergrad education in finance. NOTE: Although the presentation, printing and binding is similar to the infamous NYSE "technical" books or Wiley trader's advantage series, this is actually a good vulgarization book written by somebody having an academic training. No chaos, technical analysis or other arbitrary opinions are to be found here. In case you'd be scared by the look of it...
