Two Great Investing Books Worth Reading

By Larry Swedroe | Aug 31, 2009 |

I recently finished reading two books that I highly recommend:

The Myth of the Rational Market
It’s an entertaining history of the battle of ideas between those who believe markets are efficient and investors are rational, and those who believe that markets are inefficient and investors are irrational. Fox does an excellent job of narrating the tale without taking sides. He introduces all the major players in the battle and fills the book with fascinating tales. While the book isn’t for beginners, it’s highly readable and never dull.

The basic message Fox delivers is that while markets are not perfectly efficient and investors are not always rational, the winning strategy is to invest as if they were — in other words, invest in index funds, not actively managed funds.

The Little Book of Main Street Money
There are very few journalists who actually have investor’s interests at heart. Those that do write about what might be called the science of investing, or evidence-based investing. The rest write about the noise, or what Jane Bryant Quinn called “investment porn.”

Clements was not only one of the few that truly had investor interests at heart, but he was one of the best of the group (if not the best). I considered his weekly column a must read. The same could be said of this little book. It’s only little in size. It’s giant in terms of the number of pearls of wisdom that it contains; pearls not limited to investing, but finance in general and life as well.

I highly recommend this book especially for those just beginning their financial journey — it’s a journey you shouldn’t take without this book as a guide.

    Since you're on the topic of rational markets, you really ought
    to read Jason Zweig's "Your Money & Your Brain," which gives a
    great look at why smart people do dumb things with their
    investments.
    How can markets be rational when the people who drive them
    are not?

    I read that while ago and I agree it is a great book, for those who are serious investors, and there should not be any other kind

    I also just finished Dan Ariely's new book Predictably Irrational and can highly recommend that for all investors as well. A fascinating look at field of behavioral economics and anyone can learn a lot.

    Larry,

    If we believe that investors are not rational and the market is
    not efficient, why then you advocate index investing and
    index investing only. The whole idea of index investing is
    predicated on EMH.

    You know I am being a devil's advocate here.

    Well great question.

    First there is no evidence really that markets are inefficient. In order to show there is inefficiency you should be able to show there are ways to exploit such inefficiencies. And there is no evidence of that at all. Even the behavioralists themselves say things like while the markets are inefficient you should invest as if they are efficient ----because the costs of exploiting those inefficiencies exceed the benefits.

    Even Richard Thaler, a behavioralist professor at the University of Chicago, and a founder of the Fuller and Thaler funds designed to exploit behavioral errors admitted he invests most of his money in index funds.

    Also there is a study on behavioral funds and it found that they add no alpha over a three factor model--and they are nothing more really than value funds.

    Investors certainly do make mistakes, like chasing recency and failing to diversify but that doesn't mean that other investors can exploit their errors after costs.

    Best wishes
    Larry

    Larry,

    Thanks for the explanation.

    I actually believe markets are inefficient. Academics have documented all kinds of inefficiency. As long as they are sitting before a computer crunching data, it is pretty easy to do.

    However to actually exploit the efficiency necessitates one to overcome the behavioral bias that caused the efficiency in the first place. This is a monumental difficult task. If it is easy, the market wouldn't be inefficient.

    In my opinion, David Swensen comes close to having a systematic way of exploiting market inefficiency. What do you think?

    Even the behavioralists have failed to find ways to exploit the inefficiencies they claim exist. So from an investment strategy standpoint there is no there there. Even Professor Thaler of the University of Chicago, perhaps the leading behavioralist, invests most of his own money in simple index funds.
    You can read this paper if interested:
    Prithviraj Banerjee, Vaneesha R. Boney, Colby Wright, ?Behavioral Finance: Are the Disciples Profiting from the Doctrine?? Journal of Investing (Winter 2008).

    As to Swensen. I don't agree at all. IMO Swensen has made his name by taking risks, risks that might be appropriate for an endowment with much longer horizon than individuals (for example liquidity risk). I don't believe he is exploiting inefficiencies. Just taking risks.

    I hope that is helpful
