The Intelligent Asset Allocator (IAA) by William Bernstein does exactly what it says on the cover, it teaches you ‘how to build your portfolio to maximize returns and minimize risk’. However, I would recommend that 95% of readers not buy it. Come again? Instead, I would recommend the later book by the same author, The Four Pillars of Investing (review). Even though Bernstein himself refers to it as for the ‘liberal arts’ audience, I have an engineering background and I still like Four Pillars much, much more. It just feels more refined and easier to follow.
Both books seem to cover the same general topics, with IAA giving you a clearer mathematical basis for his conclusions. To me, here are the main ideas within the book:
1) There is very little evidence that, on the whole, actively managed funds outperform the market. In fact, if you just buy what’s been hot the last 5 years, history has shown that you would consistently underperform the S&P 500 afterwards. In other words, don’t chase past performance.
2) As risk increases, so does the return. But that doesn’t mean you should just go out and buy the one riskiest thing you can stomach. Your goal is to get the maximum return out of your acceptable amount of risk.
3) To achieve the goal in #2, you must construct your diversified portfolio out of multiple asset classes which will work in combination to reduce risk. The vast majority of your returns come from your asset allocation mix.
4) You can’t guarantee your future returns, or expect them to follow historical returns exactly. What you can do, is to optimize your portfolio using that data to give you the best chance at achieving the highest returns.
5) Minimize expenses and taxes by choosing no-load index funds with low expense ratios, and by carefully placing each asset where it will be most tax-efficient (taxable vs. tax-deferred accounts).
Finally, in the end, the book gives you some advice on how to choose your specific asset allocation and then implement it using Vanguard or DFA funds. Again, I found the same section in Four Pillars to be easier to follow, and I’ve found myself referring back to it instead of IAA to plan my portfolio.
Read Four Pillars of Investing first. If you like things like standard deviations and statistics, then pick up The Intelligent Asset Allocator. They are both excellent books, with different approaches to teaching the same material.
