This review is from: The Missing Risk Premium: Why Low Volatility Investing Works (Paperback)
Over the last 60 years, the concept of risk premium has embedded itself so deeply in finance that it is hard to think of investing without relying upon it. It's important to separate this idea from merely keeping expected value constant. If a risk-free bond pays 5 percent interest, a bond that might default must pay more than 5 percent just to have the same expected return. So the fact that junk bonds pay higher yields than investment grade bonds does not prove that there is a risk premium. We would need to show that portfolios of junk bonds had higher long-term average returns than portfolios of investment grade bonds, after subtracting out losses from default.

Falkenstein argues that there is no risk premium, and never was, so conventional investing advice is misguided. He has developed a consistent and plausible alternative explanation. This is a valuable argument, even if it is ultimately not correct. You cannot understand risk premium if you think it is obvious, you need to see why it might not exist to see how to look for it.

The book also describes an investment approach, a version of what is generally called low-volatility investing. The author is among the pioneers in this area and he advocates a reasonable version of it.

When I reviewed the author's first book, Finding Alpha, I complained about the $95 list price and suggested it should be $25 list to sell for $15 at Amazon. I don't know if he was paying attention, but if he was, he traded through my bid by a nickel. Unfortunately he didn't listen to my complaints about the copy editing and production values. There are numerous typos, including at least one where he reverses the meaning in a manner that will confuse most readers and destroy the point he's trying to make. The graphs and tables are important to the argument, but low-quality, and they assume the reader can guess what things like AnnStDev or AvgGeoRet mean. There's not a lot of jargon compared to many books, but too much given the simple elegance of the argument. There is no index.

Falkenstein retells the story of the development of Modern Portfolio Theory, the Efficient Markets Hypothesis and the Capital Asset Pricing Model, armed with a skeptical mind and knowledge of subsequent discoveries. It is a selective account, as it has to be to fit into half of a small book, but it is not unfairly selective. That is, while he leaves out many nuances and simplifies much of the history, he does confront the strongest points in favor of a risk premium. This gives a fresh look at the formative years of modern finance. I wish it had been higher-minded. I thought the low point of this account is when Falkenstein mentions unnamed people who consider Eugene Fama to be a "lightweight," and implies but does not state that he agrees. That appeared to be a smear, but in his comment and an email he explained he did not share the opinion, and disagrees with it. Nevertheless, his book gives the impression that many efficient market researchers were less open-minded, skeptical and willing to challenge their ideas than I believe they were.

Next, Falkenstein surveys 31 asset classes and investment spreads and finds evidence for positive risk premium in only 4, while 14 show a clear negative return premium. The book moves on to a more general historical and philosophic context. Why should mere exposure to risk be rewarded? There are always lots of people willing to do it. Some may even like it, after all, people gamble apparently for pleasure in casinos and dangerous sports and bar fights and lots of other areas in life. But even if everyone found risk distasteful, if people got paid for doing distasteful work then people who clean toilets would make more than professional athletes and movie stars.

Even if people did get paid for taking risk, it would not be for well-understood statistical risk like buying a volatile stock. Real risk is walking into complicated and uncertain situations, for which probability distributions are unknown. And losing money (especially other people's money) is nothing like the pain of being thought an idiot. Defying convention, underperforming the benchmark, being wrong while looking stupid; these are the unpopular forms of pain.

The single most important message in the book, which is also in Finding Alpha, is that expected return is not something you get for passive exposure to known unpleasantness, it is a niche in which you have advantages over other people. Success does not come from combining well-known bets a little better, it comes from making your own bets.

Finally, Falkenstein works out the mathematics of a market in which risk consists of underperforming the average rather than poor gross returns. He justifies this with a variety of arguments, and shows that it results in a zero premium for risk.

Even more interesting, he addresses the flaw that sinks most models without risk premia, he shows that rational, risk-averse investors will not offset the actions of irrational or risk-loving investors.

This is an important book. At worst, the effort you expend to refute its claims will deepen your understanding of conventional models. At best, it will be a breakthrough to a new understanding of financial markets and better investment results. I suspect you'll end up somewhere in the middle, which is a good place to be, especially if you hate to deviate from the benchmark.

Thanks for the review Aaron, very thoughtful. The only response I would like to make is that I personally hold Fama in very high esteem and regret it wasn't clear what I was trying to say. I wanted people to realize that pre-1992 he wasn't considered top shelf at Northwestern because he wasn't into the rigor of Gibbons, Shanken, or Ross. That methodology that prioritized rigor I find profoundly flawed, and the lack of Fama appreciation merely one of many symptoms of its deleterious effects. Good ideas in finance are rarely from abstruse math that the search for the risk premium exemplifies in major journals. So, the reference was part of my anti-rigorous-emphasis argument, not a slam on Fama, as clearly those Fama critics have egg on their face. I'm sure he'll win a Nobel prize, and be very deserving. I pay him the greatest respect by reading almost all his papers.

Rereading the book, I can see this interpretation. I'll amend the review.

I haven't read this, but isn't the core of it simply a rehash of Bob Haugen's "The New Finance?"

Haugen's book covers many different perceived inefficiencies, and only briefly the overpricing of volatile stocks (volatility/beta are relevant to about 5 out of his 70 factors, I forget exactly). His central critique of the CAPM is based on his rejection of rationality and the efficient markets hypothesis (EMH), whereas I focus on a different utility function (where, given this, the results are rational and consistent with the EMH, though not the CAPM). He focuses on over and under-reaction, where I ignore those theories and their related empirical patterns. Haugen focuses on cross-sectional equity patterns, and in this book I survey about 25 different asset-pricing anomalies, many outside the standard CRSP tapes (eg, penny stocks, junk bonds). So, they both address the failure of the CAPM, but other than that these are different books.

Thanks! I'm mostly a numbers guy, so I'll probably pass on your book and keep plugging into the market microstructure stuff.

Eric gave you a very detailed answer. A shorter version is that Haugen's book has many observations superficially organized as a thesis. The Missing Risk Premium has a clear thesis, with a lot of supporting evidence.

If you like Haugen's book, or want something like it, I think Antti Ilmanen's Expected Returns is much superior, especially for a numbers guy.

If you want something like The Missing Risk Premium, there are no second choices.

Dong Song says:
Prof Haugen shares something in common with Prof Fama. they make great observations and draw meaningful analysis that others had not been able to. Haugen's thesis is not superficial. He just would not like to participate in the modern finance theory too much because he does not trust it . I like his thesis and enjoy Fama's paper. I really like Eric F 's books. I believe in Haugen's thesis, finance is about psychology , statistics, and complexity. My university degree is math finance, but I never believe finance can be mathematicalized . It seems closed to physics, but it does at most partially.

A well stated case for the affirmative.
