Behavioral Portfolio Management: Description
The investment industry is on the cusp of a major shift, from Modern Portfolio Theory (MPT) to Behavioral Finance, with Behavioral Portfolio Management the next step in this transition. Behavioral Portfolio Management focuses on how to harness the price distortions that are driven by emotional crowds and use this to create superior portfolios. Once markets and investing are viewed through the lens of behavior, and portfolios are constructed on this basis, investable opportunities become readily apparent.
Mastering your emotions is critical to the process and the insights provided by Tom Howard put investors on the path to achieving this. Forty years of Behavioral Science research presents a clear picture of how individuals make decisions; there are few signs of rationality. Indeed, emotional investors sabotage their own efforts in building long-horizon wealth. When this is combined with the misconception that active management is unable to generate superior returns, the typical emotional investor leaves hundreds of thousands, if not millions, of dollars on the table during their investment lifetimes.
Howard moves on to show how industry practice, with its use of the style grid, standard deviation, correlation, maximum drawdown and the Sharpe ratio, has entrenched emotion within investing. The result is that investors construct underperforming, bubble-wrapped portfolios. So if an investor masters their own emotions, they still must challenge the emotionally-based conventional wisdom pervasive throughout the industry. Tom Howard explains how to do this.
Attention is then given to measureable and persistent behavioral factors. These provide investors with a new source of information that has the potential to transform how they think about portfolio management and dramatically improve performance. Behavioral factors can be used to select the best stocks, the best active managers, and the best markets in which to invest.
Once the transition to behavioral finance is made, the emotional measures of MPT will quickly be forgotten and replaced with rational concepts that allow investors to successfully build long-horizon wealth. If you take portfolio construction seriously, it is essential that you make the next step forward towards Behavioral Portfolio Management.
Behavioral Portfolio Management: Review
In spite of the fact that most current investment thinking is built around models like the Efficient Market Hypothesis, Modern Portfolio Theory, and other models the research that I and others have done does not support these theories. As a result most popular investing currently in vogue is sub-optimal on a good day. The author discusses the weaknesses in the current models drawing heavily on the work of Robert Haugen and his own research. He also brings in a large dose of behavioral finance drawing heavily on the work of Daniel Kahneman. The result is a good summary of the slow disintegration of the old thinking and insights into where investment thinking is headed.
However, Behavioral Portfolio Management: How successful investors master their emotions and build superior portfolios [ is more than that. If you are willing to actively participate in his 12-step program you can discover ways to significantly increase your investment returns. You will read about things like Myopic Loss Aversion (MLA) and how it effects your investments. How diversification may not be the best thing for you. Just to name a few issues.
In summary I found the book absolutely fascinating. With that said be aware of 2 issues: 1) although the book is particularly quantitative much of the work challenging old theories is fairly quantitative. 2) If you are firmly attached to the old theories of MPT and EMH you will find the ideas in this book to be very different and very disquieting.
