Book Review – Books on Risk (and two podcasts)
A theme you’ll hear on this blog about investing is the idea that the markets are not predictable. You may believe that I’m referring to the idea that you can’t predict returns on investments ahead of time and that’s partially true. The other part though relates to extreme risks that sweep through the markets in unpredictable ways with unpredictable results.
Aside from standard market risks, when you look at your investments it’s also important to always ask yourself: “What if I’m wrong?” Because, odds are, you will be wrong eventually. It’s just a question of degrees on how wrong it will be: A little or a lot.
The Permanent Portfolio has protection against unpredictable market risks and being wrong. If you’re wrong, you’re not going to be wrong so much that you take a crushing blow to your portfolio (because your asset allocation is widely diversified in relatively small chunks). We should also understand though that all investments have risk. Without risk, you will not get rewards. So risk must be taken to grow a portfolio, but it must be done with specific goals in mind. We need profits, but we also need defenses against an unknown future.
In this light, I’d like to share with you some books and podcasts that I think really hit at this problem of risk, uncertain futures and protecting yourself against being wrong. They may help you understand why diversifying and eliminating unnecessary risks in your portfolio is so important and why being wrong does not have to be fatal if you handle it correctly.
First there is John Allen Paulos and his book A Mathematician Plays The Stock Market. This 2003 title is one of a series of excellent books written about his worldly observations as a mathematician. In this case, the book details his own personal story of losing money in the stock market and how uncertainty rules. It’s an interesting look at many concepts you see in the investing world with respect to stocks vs. bonds, efficient market hypothesis, chaos theory, etc. And, best of all, it’s a very easy and fun read with almost no math but high level explanations of many concepts with real-world examples. He has a number of books written in his “A Mathematician” series exploring everything from innumeracy in society to his experiences investing (and losing) lots of money in Worldcom as he discusses in this book. The bottom line is that risk is real, markets are random, and trying to beat it can be very costly. His dedication reads:
To my father, who never played the market and knew little about probability, yet understood one of the prime lessons of both. “Uncertainty,” he would say, “is the only certainty there is, and knowing how to live with insecurity is the only security.”

Now that’s a dedication I can get behind! That is the core philosophy of how the Permanent Portfolio is designed to operate.
Next, there is Nassim Nicholas Taleb and his series of books on chance. First there was Fooled By Randomness followed by The Black Swan. Both of these books explore the idea of unpredictability in the world. While his advice is largely being linked to finance today (he was a former trader), his observations come into play in many areas of life. His book, The Black Swan, pre-dated the 2008 crash involving Fannie Mae but said this in one of his footnotes:…the government-sponsored institution Fannie Mae, when I look at their risks, seems to be sitting on a barrel of dynamite, vulnerable to the slightest hiccup. But not to worry: their large staff of scientists deemed these events “unlikely.”
Nassim Taleb – The Black Swan Pg. 225
I’d say he certainly called that one correctly.
I also think you’ll enjoy these two podcasts from Nassim Taleb. One recorded in 2007 talks about his book The Black Swan. The second was recorded in 2009 after the market meltdown as an after-action report on what he had written and said before:
Taleb on Black Swans – April 30, 2007
Taleb on the Financial Crisis – March 23, 2009
One thing about Taleb is while he has disdain for most fields of economics (and especially the very silly Keynesians), he does have an affinity for the Austrian Economic School and their dislike of the over-application of mathematics in economics for what is, essentially, a human behavioral problem (aka. scientism). Why does this matter? For one, you cannot model risks accurately with standard statistical methods because human behavior is not predictable. Secondly, Harry Browne was a firm believer in Austrian Economics and the Permanent Portfolio design, at its absolute core, is based on the Austrian School’s theory on monetary cycles (a lengthy topic for another day) and embracing unpredictability in the world. In fact, I think that one of the reasons the Permanent Portfolio is good at dealing with market risk is because the Austrian Economics school is right about a great many things. This outlook helps to drive the portfolio down the right path over time avoiding serious pitfalls and dangerous assumptions about the future.
With these three books and two podcasts you will understand more about market risk than most professional investors and economists. Seriously. Combine that with Harry Browne’s podcasts, and his own previous books, and you’ll be well versed in the dangers of the unpredictable in the investing world and how to position yourself to deal with them.

I really enjoyed the Paulos book, in fact, even more than I liked The Black Swan. Thanks for the great tips.
