Book Description

Jan. 10 2012
In this major revision of his investment classic, one of the premier investment managers introduces vitally important new findings in psychology that show why most investment strategies are fatally flawed and his contrarian strategies are the best way to beat the market.

The need to switch to a new approach for investing has never been more urgent. The Crash of 2007 revealed in dramatic fashion that there are glaring flaws in the theory that underlies all of the prevailing investment strategies—efficient market theory. This theory, and all of the most popular investing strategies, fail to account for major, systematic errors in human judgment that the powerful new research in psychology David Dreman introduces has revealed, such as emotional over-reactions and a host of mental shortcuts in judgment that lead to wild over and under-valuations of stocks, bonds, and commodities and to bubbles and crashes. It also leads to horribly flawed assessments of risk.

Dreman shows exactly how the new psychological findings definitively refute those strategies and reveals how his alternative contrarian strategies do a powerful job of accounting for them. He shows readers how by being aware of these new findings, they can become saavy psychological investors, crash-proofing their portfolios and earning market beating long-term returns. He also introduces a new theory of risk and substantially updates his core contrarian strategies with a number of highly effective methods for facing the most pressing challenges in the coming years, such as greatly increased volatility and the prospect of inflation. This is every investor’s essential guide to optimal investing.

Product Description

Review

“David Dreman is known on Wall Street as a contrarian, a label that fails to appreciate his deep knowledge of the market and research into investor psychology. In Contrarian Investment Strategies: The Psychological Edge Dreman lays bare the deficiencies of the efficient market hypothesis, the investment rationale that states stock prices incorporate all known information. He also provides decades worth of data to show the woeful inaccuracy of analysts' forecasts. With the knowledge that the Street is marching to a flawed drumbeat, Dreman offers advice on how to react when markets misprice assets. Dreman has made a career of leaning heavily against the prevailing wind and for the most part, been highly successful. For those wary of following the herd, Dreman's thinking is revealing.” –Hebert Lash, Correspondent, Reuters

There are so many strategies in the world of finance. Mr. Dreman talks about some of them, what works and what works better. The first two hundred pages make for dry reading but sets the stage for the last two hundred pages. If you intend on being a passive investor this read will optimize your passive efforts. Mr. Dreman may be contrarian but he shows how it does work over time. I have been reading investing books for quite a number of years and this is among the best.

Every serious investor should read David Dremans book, its a must read, he breaks down bubbles and crashes and talks about the falsehoods of emh and risk management. I'm a huge fan of his and would suggest anyone interested in reading David Dremans book also look at James Montier's book as well.

5.0 out of 5 stars The Role of Psychology in Investing. Jan. 10 2012
By AdamSmythe - Published on Amazon.com
Format:Hardcover|Verified Purchase
This is a substantial, well-organized work by one the pioneers in what is today called behavioral finance/investing. As he has been doing since the late 1970s, author David Dreman states his case that the academically-popular Efficient Market Hypothesis (sometimes oversimplified as the "random walk theory") doesn't adequately recognize or account for the fact that psychology plays an important part in investment decisions. To help make his points, Dreman guides the reader through major investment bubbles and panics, starting back with Holland's tulip bubble in the 1630s and progressing through the more recent real estate bubble. (Some of the important aspects of volatile markets have remained quite similar over the centuries. The reason, according to Dreman, is that while the investing environment may have changed over the years, human psychology hasn't changed nearly as much.) Dreman makes his arguments, backs them up with lots of data and discussion, and offers his views on how to (1) make volatile investment environments seem less scary, and (2) take advantage of the opportunities that develop in volatile times. You don't need degrees in finance, business, economics or psychology to enjoy this book. It is written for the intelligent lay reader, and my guess is that most people with an interest in investing will find it very readable.

This is Dreman's fifth book on investing (see below), and given the similarity of titles I wondered just how different this book would be from the earlier versions. Here's a list of his works:

Psychology and the Stock Market: Investment Strategy Beyond Random Walk, written in 1977,

Contrarian Investment Strategy, (1980),

The New Contrarian Investment Strategy, (1982),

Contrarian Investment Strategies - The Next Generation, (1998) and

Contrarian Investment Strategies: The Psychological Edge, (2012).

Having followed Dreman for a long time and read his books, here is my conclusion: The current version is substantially new and makes for an informative, enjoyable read. However, while the illustrative material and discussion are largely new, Dreman's arguments for contrarian investing are, at their root, similar to those he's made since 1977. If you haven't read his earlier books, this is an excellent introduction to and exposition of contrarian investing. If you have read his earlier books and are looking for a different investment theme, look elsewhere. If you've read his earlier books and are interested in more material on contrarian investing, there's a lot of good information in this book. I got my money's worth.

The book is organized into five parts:

Part 1: "What State-of-the-Art Psychology Shows Us." This part includes a history of manias and bubbles, with emphasis on the aspects of human psychology that contribute to these episodes.

Part 2: "The New Dark Ages." Dreman describes how the Efficient Market Hypothesis came to be accepted by many academics and how it affected the way large institutions (mutual funds and pension funds, for example) invested their money.

Part 3: "Flawed Forecasting and Poor Investment Returns." Dreman argues that economic forecasting is very difficult, and investment strategies based on developing a better forecast of next year's GDP are going to prove to be disappointing sooner or later.

Part 4: "Market Overreaction: The New Investment Paradigm." These chapters represent the core of Dreman's contrarian strategies. Simply stated, markets have a demonstrated history of going to extremes, each time with a believable "this time is different" story. However, if you can keep from becoming caught up in the conventional wisdom of the day, you can work to exploit market overreactions.

Part 5: "The Challenges and Opportunities Ahead." Dreman discusses today's specific economic and investment environments, problems and possibilities.

Don't buy this book with the expectation of discovering specific stock recommendations, because you won't find them. Similarly, don't buy this book with the expectation that the author hasn't fallen for some of the same mistakes he describes in this book, because he has. Investing is tough, and every investor is going to make plenty of mistakes. However, if you want stimulating food for thought, this is an interesting and informative book. While I wouldn't recommend it to a confirmed "technical" analyst, I do recommend it to those who are open to the concept of contrarian investing.

1.0 out of 5 stars Disappointing waste of time April 6 2012
By words - Published on Amazon.com
Format:Hardcover
I was very disappointed with this book. I work professionally in the investment industry and have my whole life, and have read dozens of books about investing, but rarely has one let me down like this one. And the reason is very simple: Dreman seems to have forgotten who this book was written FOR. It is the reader who spends their money and their time on this book, and it is the reader who should be rewarded for this. Such is not the case. At least 80% of this book is dedicated to Dreman arguing with his nameless critics, or the "academics" and EMH proponents who just aren't smart enough to see things his way. Obviously, anyone reading a book like this is interested in investing strategies--in picking up insights that help them invest successfully and perhaps even beat the market. I really didn't need to spend several hundred pages hearing about why EMH hypothesis is wrong. Anyone who picks up this book probably feels this way already, and doesn't need more than a page or two of reminding. The subject is dealt with successfully (and briefly) in other investment books, by Klarman, Greenblatt, Greenwald, etc, but NONE of those authors wasted as much time as Dreman does on it. It seems that Dreman feels himself slighted by the academic community, and he uses this book to beat that point into the ground. If this had been titled "Why the Academics Are Wrong, in 500 Pages", I personally would have saved my money and my time. The publishers should be ashamed of themselves on this one. In the end, I learned nothing here, and felt cheated by the book. I have to give this one star, and feel compelled to warn other readers that there is very little of value in this book. I hope you will save your money.

5.0 out of 5 stars Insightful Feb. 4 2012
By Behavioral Investors - Published on Amazon.com
Format:Hardcover|Verified Purchase
Having read and enjoyed his 1997 "Contrarian Investment Strategies - The Next Generation", I was pleased to see this comprehensive updated edition by longtime contrarian value investor David Dreman. By and large the content of the book is entirely new; encompassing a brief discussion of research findings in behavioral finance and their relevance to value investing, a fairly devastating critique of the widely-used conventional concepts of risk and return embodied in the efficient market hypothesis (EMH), and a thorough (though not enitrely novel) review of the significant long-term outperformance of several basic value investing strategies.

BEHAVIORAL FINANCE: THEORY AND APPLICATIONS

Readers who have followed behavioral economics may find his descriptions occasionally a little stilted, but in general Dreman provides a useful summary of several basic findings on human behavioral biases and heuristics in financial decision-making, and how these create opportunities for value investors to outperform significantly over the long term. As I think most of its practitioners would agree, at its core behavioral investing is essentially value investing: an attempt to avoid and reverse the systematically poor performance of the majority of mainstream investors by avoiding biases through an explicit focus on objective measures of business value.

As a neurologist, I was particularly interested by Dreman's mention of the role of the neurotransmitter dopamine in expectation and reward. As Dreman expostulates, a large part of the significant excess returns of value stocks are realized subsequent to positive earnings surprises, which have a systematically much greater positive effect on stocks which are undervalued using basic metrics than on their overvalued peers. The representativeness heuristic causes investors to simplistically label individual companies as "good" or "bad" investments regardless of their current valuation, developing binary and often unrealistic expectations about future results. Overconfidence and biased self-attribution lead to inaccurate perception of the accuracy of earnings estimates developed by analysts and investors themselves, making surprises both far more frequent and far more extreme than conventional investors anticipate. As a gross simplification, the neurobiology of the dopamine reward system conditions human beings to experience pleasure and pain in proportion to the degree to which their actual experiences depart from their prior expectations of them. The interaction of these biases sets the stage for extreme positive returns from upside surprises in the undervalued stocks neglected and shunned by most investors, as well as disproportionately painful downside surprises in the most popular stocks (the very stocks chased by the majority of individual and institutional investors, who coincidentally have performed so poorly while value investors have done rather well).

Dreman may somewhat overstate the degree to which a single such surprise accounts for the durable long-term outperformance of value stocks: the evidence shows that the difference in excess return between undervalued stocks experiencing positive and negative surprises becomes less significant after 3 quarters, while both categories outperform the market strongly for more than a 5 to 8 year period. However, I strongly agree that understanding the actual behavioral and neural substrates of human decision making provides a much more comprehensive and powerful framework for investment strategy than a blind reliance on convenient EMH assumptions that remain impossible for most conventional investors to abandon, yet have been thoroughly and demonstrably discredited by years of empirical evidence.

"THE NEW DARK AGES": A FRONTAL ASSAULT ON EFFICIENT MARKET ASSUMPTIONS

I have always had somewhat mixed feelings about attempts to directly attack the efficient market hypothesis in book form. The degree of commitment to assumptions of rational behavior among conventional investors is so ingrained (in the face of decades of clear evidence to the contrary) that such attempts are almost invariably preaching to the choir. From a selfish perspective, it's more profitable to personally identify and act on mispriced investment opportunities resulting from market misperceptions than to spend time proselytizing the merits of deep value investing to a general audience, many of whom will realistically never be able to embrace such a strategy for behavioral reasons. Nevertheless Dreman provides a trenchant and valuable critique, with a particular focus on instances where EMH assumptions about the nature of risk and return have been repeatedly violated. In spite of some preexisting familiarity, I came away rather amazed by the lack of good real-world evidence behind many of the financial models still being used today, and the resulting inability of conventional investors to consider factors such as liquidity, leverage, and intrinsic business value in thinking about risk and return.

Dreman is at his best when narrating his own experiences as an analyst and investor during multiple periods of optimism and pessimism, spanning multiple fascinating periods of irrationality including the Nifty Fifty, the "go-go" 1960s and subsequent bear market and rejection of stocks, the turn-of-the-century internet bubble, and so on. His clearly worded exposition of how naive EMH assumptions about the nature of volatility, risk, and liquidity contributed to the 1987 crash (and yet again the Long Term Capital Management debacle, and the 2000s mortgage securitization boom and bust) was particularly telling.

CONTRARIAN INVESTMENT STRATEGIES: THE PSYCHOLOGICAL EDGE?

In view of the above insights and the title, I was hoping for a more nuanced discussion of some of the specific applications of behavioral finance in fine-tuning a basic value investing approach. The "contrarian" strategies discussed in the book are neither particularly novel nor explicitly different from basic ratio-based value strategies (price/earnings, price/book, price/cash flow, dividend yield, and rankings of the same metrics relative to firms within the same industry) which should be familiar to any reader of Graham or O'Shaughnessy, or indeed to most market participants. There is something to be said for adhering to a rules-based value methodology that removes human bias from the equation. For example, Joel Greenblatt has recently presented evidence that most individual and institutional investors who attempted to individual stock selection based on adding their personal judgements to results of a basic "Magic Formula" screen have in general substantially underperformed a simpler mechanical strategy using raw formula rankings themselves. For most investors, an attempt to apply subjective judgement simply reintroduces the biases which a formulaic approach to value investing is meant to eliminate.

However. the fact remains that overreliance on raw reported valuation ratios can in many cases be a naive strategy with significant pitfalls for investors. As one trivial example, in recent years many investors have been seriously blindsided by investing in fradulent Chinese reverse mergers, where apparent undervaluation on reported numbers could in most cases be belied by a modicum of individual research by a seasoned value investing practitioner, however subjective this may seem. Many entirely mechanical "quant" strategies being marketed to the public as value investing have in fact backfired. To the extent that very simple ratio-based methods become popular, there will be an increasing premium for value investors who can successfully incorporate subjective judgements while attempting to consciously avoid behavioral errors. This is likely to be a difficult and nuanced task that few can realistically achieve, but is an important part of the skill set of highly successful value investors such as Warren Buffett, so it's a pity that Dreman did not discuss the many instances where behavioral finance can help guide judgements of a more subjective nature.

CONCLUSION

Apart from the basic value strategies described above, the final chapters do include some discussion of several important situational sources of market risk arising from behavioral factors. Dreman again makes points worth repeating about the intellectual bankruptcy of the traditional EMH concepts of risk based on historical volatility and beta, assumptions still in use today by all too many market participants despite repeated devastating failures in the past. Drawing insightfully on the lessons of 1987 (portfolio insurance), 1998 (LTCM leveraged arbitrage) and 2008 (mortgage securitization), Dreman correctly emphasizes the significant roles of liquidity and leverage as intrinsic sources of real risk, which are strangely not perceived as risk by the majority of conventional investors.

All in all, Dreman's book is a solid presentation of many core research findings about the long-term outperformance of basic value strategies, and draws valid parallels between basic value investing and behavioral finance, in addition to illustrating how the prevalence of EMH assumptions contribute to the development of often glaring misperceptions by conventional investors about real-world risk and return. Readers more interested in an introductory exposition of behavioral and neuroeconomic research may enjoy Jason Zweig's Your Money and Your Brain: How the New Science of Neuroeconomics Can Help Make You Rich; while those wanting a more comprehensive exploration of direct applications in behavioral finance may be interested in James Montier's Behavioural Investing: A Practitioners Guide to Applying Behavioural Finance (The Wiley Finance Series), or The Little Book of Behavioral Investing: How not to be your own worst enemy (Little Books, Big Profits (UK)) by the same author.

5.0 out of 5 stars 5 star book from a pioneer on behavioral investing and a true contrarian March 8 2012
By Brian - Published on Amazon.com
Format:Hardcover
This book is updated recently by the author, David Dreman, a pioneer on behavioral investing and a true contrarian. He used well-organized studies to argue against the Efficient Market Hypothesis and CAPM. Although EMH has been disproved by black swan events in many circumstances, it still has a large support base due to the lacking of a better theory. CAPM was rejected by Eugene Fama, father of EMH as early as 1992, who stated that "Beta as the sole variable in explaining returns on stocks is dead." Beta/volatility, although a good measure of the daily fluctuation of the stock or market risk, has limited explaining power on long term risk and return.

The author's extensive research supports that deep value stock with low P/E, P/BV, P/CF and High yield will outperform the market over the long run. He showed that a positive surprise has much more impact on low P/E stocks than high P/E stocks, while a negative surprise has much bigger impact on high P/E stocks. He also showed that compared to the initial event trigger (the surprise), a reinforcing event has limited impact to the performance. Thus continued good news has limited impact on a high flyer with high PE, but a negative surprise will hammer the stock. With this psychological factor in mind, by buying deep value stock with existing negative sentiment, an investor will have limited downside even when bad news continues but will have substantial upside gain when things turn around.

3.0 out of 5 stars Worthwile content, though a little too long Jan. 28 2013
By Glenn Corey - Published on Amazon.com
Format:Hardcover|Verified Purchase
On the one hand, I agree with much of what the one-star reviewer said in that the book is a bit long and spends too much time trying to convince the reader that markets aren't efficient. It seems like Dreman is trying to do too much: write a useful, practical book that the individual investor can use in making smarter investment decisions and at the same time establishing his academic bona fides. The second goal could have been attained by summarizing the existing literature on the topic and providing all the references a curious reader might have needed to explore the topic in more detail. I also got the impression, like the one-star reviewer, that Dreman feels slighted by the academic community for not taking him seriously when, in fact, he turned out to be right. Perhaps this is justified, but I thought it veered off course a bit without adding anything for someone simply looking for practical investment advice.

On the other hand, because psychology is so important in investing but the average investor still doesn't seem to realize that, Dreman needed to spend some time making his case for exactly why the strategies he would eventually present are effective. I think the book is organized such that an intelligent reader would be able to figure out what parts could be safely skimmed and which should be paid attention to if not all the material is of interest.

The weakest part of the book is the analysis of the ongoing financial crisis. In my opinion, the moral hazard introduced by the government, including the Federal Reserve, by bailing out the big banks is the single most important factor that created the current crisis. The Fed's big bailouts started soon after it was established and has conveyed to the big banksters that the Fed will always come to the rescue if things get bad. So go ahead and take as much risk as you want since you won't have to pay the penalty, and as long as things work out, you get to keep your winnings. And of course the most recent bailouts did nothing to lead the banksters to believe this won't happen continue. Dreman seems more optimistic about the future than I believe is warranted (not that he thinks it'll be a cake walk, but I don't believe he thinks it'll get too much worse), and he doesn't emphasize the importance of still haven't a full trading/investment plan in place with rules about when to get in and when to sell.

However, the strategies and psychological considerations make the book a worthwhile read, in my opinion. While it's not the best book on investing I've read, it's certainly not the worst, either.
