Concentrated Investing


Conscientious employment, and a very good mind, will outperform a brilliant mind that doesn't know its own limits.

-Charlie Munger 1

Concentration value investing is a little-known method of portfolio construction used by famous value investors Warren Buffett, Charlie Munger, long-time Berkshire Hathaway lieutenant Lou Simpson, and others profiled in this book to generate outsized returns. A controversial subject, the idea of portfolio concentration has been championed by Buffett and Munger for years, although it moves in and out of fashion with rising and falling markets. When times are good, portfolio concentration is popular because it magnifies gains; when times are bad, it's often abandoned-after the fact-because it magnifies volatility. Concentration has been out of favor since 2008, when investment managers began in earnest to avoid what they perceive as a risky business practice.

It is time to re-visit the subject of bet sizing and portfolio concentration as a means to achieve superior long-term investment results. We will start by examining some of the academic research on concentration versus diversification on long-term investment results. One central feature of the discussion surrounding concentration is the Kelly Formula, which provides a mathematical framework for maximizing returns by calculating the position size for a given investment within a portfolio using probability (i.e., the chance of winning versus losing) and risk versus reward (i.e., the potential gain versus the potential loss) as variables. The Holy Grail for any investor is a security with a high probability of winning and also a large potential gain compared to the potential loss. Given favorable inputs, the Kelly Formula can produce surprisingly large position sizes, far larger than the typical position size found in mutual funds or other actively managed investment products. In addition, some academic studies point to the diminishing advantages of portfolio diversification above a surprisingly small number of individual investments, provided each investment is adequately diversified (no overlapping industries, etc.). Also, portfolios with a relatively smaller number of securities (10 to 15) will produce results that vary greatly from the results of a given broadly diversified index. To the extent that investors seek to outperform an index, smaller portfolios can facilitate that goal, although concentration can be a double-edged sword.

Investors can employ the traditional value investing methodology of fundamental security analysis to identify potential investments with favorable Kelly Formula inputs (a high probability of winning, and a high risk/reward relationship), in order to maximize the chances of significant outperformance, as opposed to significant underperformance, with a concentrated portfolio.

We have unparalleled access to investors in Warren Buffett's inner circle. Interviews with several highly successful investors who have achieved their success employing a concentrated approach to portfolio management over the long term (at least 10 to 30 years) will be incorporated throughout this book. One common feature of these investors is that they have had permanent sources of capital, which has changed their behavior by allowing them to endure greater volatility in their returns. Most people seek to avoid volatility in general because they perceive increased variance as an increase in risk. The investors we examine, however, tend to be variance seekers. At the same time, however, they are able to produce returns with low downside volatility compared to the underlying markets in which they invest.

This book profiles eight investors with differing takes on the concentration investment style. The investors and the endowment interviewed are contemporary. One of the investors profiled, Maynard Keynes, is now a historical figure, but was the early
