This book is different, and is a much better book. It also seems to me that the sector analysis coverage is a little more thorough (although I have not opened them up side by side to tell).
The only downside of this book is I don't think it gives you as many practical tools for tracking the business cycle and sector rotation as Pring's book, how to select stocks using technical analysis. It will give you the basics though, relying heavily on comparative relative strength.
If you want to see the big picture and understand how the markets are tied together, I can without hesitation recommend this book. There are several other books that complement this one as well.
Although I respect Mr. Murphy's work, he, like most technical analysts, can tell you with 100% accuracy exactly what happened.........yesterday. He really did do a good job on a very difficult topic, but the historical analogies referenced imply that the interrelatedness is rudimentary and predictable.
After a very detailed history of the four major market relationships, Murphy finally concludes that some of the historical tendencies are currently being challenged and that only time will tell if a new relationship has emerged or if history will again be proven right.
In the interest of disclosure, let me say that I do not know Mr. Murphy; nor has he or his publisher solicited this review. His editor at Wiley, Pamela Van Giessen, also edited a book I wrote on The Psychology of Trading. Knowing Ms. Van Giessen's integrity in a business that too often lacks that virtue, and having enjoyed Murphy's first book on the topic, I was eager to give "Intermarket Analysis" a thorough read.
Murphy begins with a review of the markets from the 1980s, recapitulating themes from the first book, including the close linkages among the currency, bond, commodities, and stock markets. His discussion of the role of oil and gold in economic slumps and booms is first rate, as he traces the interplay among these markets during the first Persian Gulf War and then during the "stealth bear market" of 1994. Throughout these presentations, Murphy captures qualitative relationships between markets that provide inspiration for traders interested in quantitative modeling. For example, the relationship between oil stocks and crude oil prices and the CRB/Bond Ratio are promising tools in capturing shifts in commodity prices that tend to impact the stock indices. I was particularly intrigued by his presentation of sector relationships during economic/market cycles, including the relative performance of cyclical and consumer stocks.
Where Murphy's book really shines, however, is in its explanation of intermarket relationships in a deflationary environment. He captures these relationships in his account of the recent bear market, drawing upon such diverse intermarket relationships as semiconductor stocks, Japanese markets, the Australian dollar, and the yield curve. This alone is a major advance over his previous text. At the end of the book, he traces the start of the recent bull market, illustrating the transition from a deflationary environment to an inflationary one--a pattern that also occurred after the great bear market of the 1930s.
Weaknesses in this book, from this reviewer's perspective, include an overemphasis on charts and visual data at the expense of quantitative treatments and a glib treatment of the Kondratieff Wave (long-term economic cycles). That having been said, this is an excellent market book. The presentation of sector rotation during economic cycles alone provided enough ideas to keep me busy with modeling efforts. Chart-based technical analysts and quants alike can find value in Murphy's work.
