Summary: This book is a disappointment
Review: As a market analyst for an oil company, I spend considerable effort in trying to find new ways and theories to "decode" the markets and overcome uncertainty. I had hoped Mr. Peters book would offer a model of analysis to test and hopefully use. Unfortunately, the deeper you get into the "meet and potatoes" of this text, the more disappointing it gets. This book offers nothing. Readers less skilled in the subject matter might attribute this to their shortcomings or lesser math skills. Readers well-versed in this subject matter will easily determine that this text is a waste of time...

Summary: Nice presentation of Hurst processes
Review: For readers with more then a passing interest in fractal geometry the first sections of this text can be skipped. However, the sections on R/S noise, Hurst exponents / processes, Levy flights et al are clearly presented to audiences with even remote knowledge of time series / market phenomena. Overall the text makes and presents a case --- and offers an alternative --- against the claim that markets are goverened by white noise processes. The alternatives of pink / brown noise presented here are both compelling and suggestive and even at times *conclusive*. Further, the author goes beyond criticism and provides alternative pricing methodologies that work from these alternative approaches. Researchers and practioners seeking non-gaussian methods are provided explicity with such methods in this text.

Summary: Superficial, mystical, factually incorrect at times.
Review: I am very disappointed with this book. In spite of the trendy words "fractal" and "chaos" the field of nonlinear dynamical systems is not new, and this book is reminiscent of a cursory overview of an advanced undergraduate mathematics class in time series analysis. The book also contains statements which are simply untrue. For example (p.19) The author claims that "Upon discovering this 'statistical memory' (inherent in a game of single-deck blackjack), casinos responded by using multiple decks, ... thus eliminating the memory". This is simply wrong, the statistical memory still exists in multiple-deck blackjack, and is exploited by blackjack players every day. Even worse, the "Fractal Market Hypothesis" itself is stated in such a general and ill-defined manner that you may be left wondering what exactly the hypothesis is. There are certainly problems with the traditional efficient market hypothesis, but this is no excuse for mystical hand-waving about "fractals". The useful information in the book could be written in a pamphlet of a few pages at most. Good luck.

Summary: awful presentation, no details, useless
Review: I am very disappointed. This book does a lot of critic of traditional finance, keeps promising a new magic approach, but, in fact, it has nothing to offer. It does talk a lot about fractals, nonlinear dynamic, lang-range dependence, but it does not go far beyond simple talks. It gives no details, no proofs, no mathematical modeling. It is just one of those books which critisize a lot, promise a new way, but, by the time you end reading, you have no idea what this new way is about. And the last thing - notation and presentation. It is the most awful presentation I have ever seen, it looks like the whole text was printed using Notepad. I simply do not understand how they could possibly publish it this way.

Summary: Good for newcomers to FMA
Review: I have found Mr. Peters book excellent. I am no mathematician and still I found it easy to read. I was interested in learning about fractal market analysis and I found what I needed in this book.

Summary: correction
Review: I have received a response from the author to my review. It would be only fair to present it here: <<Mr. Marmer: I'm curious. Why did you review my book as if its a textbook when right in the introduction I warn that the approach is "primarily conceptual?" This book was never intended as a text book and was not written for academics. As to the presentation, the book is now seven years old. At the time it was the best Wiley (or most other publishers) could offer. Ed Peters>>

Summary: Almost useless
Review: In this book, Peters explains general capital market in an interesting way; but when he gets into the Fractals - the main theme of the book, he seems to just pick things up from previous research papers and condenses them. At the end of the day you will be wondering if it is worthwhile to purchase and read the book after all. On the editing side, I think Wiley could have done better. The math in the book is typeset in a programming language style and you have to give extra effort in order to read them. The three stars is for being one of the very few works available in this field.

Summary: Hands down the best book on finance I have ever read.
Review: Reviewed by Michael P. Corning
Edgar E. Peters wasn't satisfied with the Efficient Market Hypothesis (EMH). With the publication of his first book, Chaos and Order in Capital Markets, John Wiley & Sons, New York, 1991, he went public with his concerns about its underlying assumptions and with its empirical shortcomings. That book, a manifesto really, was followed last year by Fractal Market Analysis: Applying Chaos Theory to Investment & Economics (FMA). Where his first book broke ground, FMA has laid the foundation of a new conceptual infrastructure of capital markets.
Risk From The Past
Much of Peters argument is based on two things: one hundred three years of daily Dow Jones Industrial Average data, and Rescaled Range (R/S) analysis. He begins FMA by demonstrating that capital market returns in the United States are not a truly random walk. Instead, he contends they are a biased random walk and indicate a long memory process; they are persistent. Specifically. he characterizes their short term behavior (less than 1,200 days) as a stochastic nonlinear process and their long term behavior as a nonlinear dynamic, or chaotic, process. As a result, he enlarges the definition of risk to include a phenomenon he discovered about persistent processes: they are mirrored by antipersistent ones. If persistent processes are less random than random ones, antipersistent processes reverse themselves more often than random ones. An early insight due to this discovery is that risk in not merely the deviation from an expected value, viz., standard deviation, but the velocity of the second difference of price changes.
Peters offers the Stable-Levy, or fractal, frequency distribution as a more faithful representation of capital markets. When two key variables are fixed at certain levels, the normal distribution becomes a special case of fractal distributions. To hear that the random walk is a special case should be no more surprising than to hear that visible light is a special case of the electromagnetic spectrum. It is not so much a matter of losing something; instead, vast amounts of knowledge remain invisible as long as the old assumption remains intact and tools tuned to the different frequencies remain undeveloped. Instruments tuned to gamma, X-ray, infrared, and radio frequencies have shown astronomers far more about our universe than the special case of visible light ever could.
Both these facts, that finance time series are not random and that the Gaussian assumption is a special case of fractal distributions, suggest that:
1. major rethinking about risk and diversification is necessary,
2. new statistical tools need to be created, and
3. very exciting discoveries are in store for us.
Risk in the Present
While examining the same historic data at different time scales, Peters made another discovery. He found that the frequency distributions of investment horizons ranging from 1-day to 90-day intervals had the same shape. As a result, he concluded that capital markets do not have a characteristic time scale (an important attribute of fractal systems). Instead, he suggested that this phenomenon represented what he called "self-similar risk."
In Peters' view, investors don't struggle against each other trying to attain an above average rate of return (at the expense of the seller) as much as they sustain each other and diversify each other's risk by keeping the market liquid. As long as long-term investors remain long-term investors, they are willing to step in and buy securities that are unwanted by traders on shorter investment horizons.
Risk of the Future
In spite of the highest discipline, crashes happen. The EMH demurs. Crashes and stampedes are not efficient concepts. Copernicus had a similar problem. By placing the Sun at the center of the solar system, he was able to explain the wandering behavior of the planets-except for Mars.
The EMH finds itself in a similar predicament. As long as it clings to its simplifying assumptions like a jealous lover, it will never be able to explain why crashes and stampedes happen. The FMH, on the other hand, not explains why, it begins to construct a world view which explains how they happen, as well.
In the long term, Peters conjectures, capital markets behave like nonlinear dynamic systems. Their time series have all the requisite attributes; among them, sensitivity to initial conditions, and a fractal dimension. In addition, through the use of R/S analysis, Peters can identify the nonperiodic cycles, known in chaos theory as attractors, so characteristic of chaotic systems.
It may be this latter feature that will have the greatest impact on our understanding of risk and our techniques to minimize it. Though he does not explicitly suggest it in Fractal Market Analysis, he has speculated in earlier papers that sufficient understanding of the nonlinear dynamics of capital markets may provide a theoretic basis for market timing and tactical asset allocation.
Final Thoughts
I conclude this review with a few of my own comments about risk.
First, we risk making two types of errors when faced with a new and provocative world view. Type I: We too quickly appropriate a new idea or theory. Type II: We too quickly dismiss a new idea or theory. With Type I errors we agree without understanding; with Type II: we disagree without appreciating. The former is naive, the latter is insolent. With Type I errors we are not fully utilizing our critical faculties; with Type II errors we are forgetting our intuitive. Ignorance is non-market risk. We have an obligation to our clients to diversify it away, and the best way to do that is with an open and critical mind.
Finally, at the risk of overstating it, I would have to describe both of Peters' books as inspired. I say that because they not only informed me, they enlightened me. They changed the way I see the world, and they affected me at an emotional level. I have never before encountered a book at once so intellectually demanding and accessible. For me, the measure of a great book is taken in the number of times I return to it and the degree of new understanding each reading yields for me. In my library, Peters has few peers.
