Charlie Munger: Why Quant Funds Are Stupid
By The Long-Term Investor
Key Concepts
- Machine Intelligence (AI): The application of artificial intelligence, particularly in complex tasks like Go.
- Capital Allocation: The process of distributing financial resources to various assets or projects.
- Physics Envy: The desire to apply precise, formulaic approaches, similar to physics, to complex, unpredictable fields like investing.
- Competitive Advantage Durability: The long-term sustainability of a company's edge over its rivals.
- Ecosystem Value: The comprehensive value derived from an interconnected network of products, services, and users (e.g., Apple's ecosystem).
- Circle of Competence: The area of business or industry that an investor understands thoroughly.
- Underestimation of Founders/Companies: The failure to fully grasp the potential or capabilities of certain individuals or businesses.
- Age-related Stupidity: A humorous term used to describe the limitations or blind spots that can come with age and experience, particularly in rapidly evolving fields.
Views on Machine Intelligence and its Impact
The speaker expresses a skeptical view regarding the transformative power of machine intelligence, particularly in the realm of capital allocation and investing. While acknowledging significant achievements, such as machines beating the best human Go players, he believes there is "more hype in that field than there is probable achievement." He personally feels too old to learn computer science or machine intelligence and doesn't foresee it fundamentally changing the world "hugely."
From an investment perspective, he states, "I don't really think they bring much to the table in terms of capital allocation or investing." This suggests a belief that human judgment, experience, and understanding of broader business principles remain paramount over algorithmic or AI-driven approaches for investment decisions. Charlie Munger humorously adds that much of what is presented as AI in finance might be "very fee earning twaddle," implying it often serves to generate fees rather than genuine value.
Investment Philosophy and Capital Allocation
The core investment philosophy revolves around identifying businesses "worth buying" by focusing on fundamental principles rather than complex formulas. The speaker criticizes what he calls "physics envy" – the academic tendency to seek precise, formulaic solutions for investing, akin to physics. He argues that "the world isn't like physics outside of physics," and such "false precision just does nothing but get you in trouble." Instead, he advocates for mastering "general ideas" and slowly improving one's "judgment."
A key tenet is the focus on the "durability of the competitive advantage." The investment team assesses whether their "opinion might be better than other people's opinion in assessing the probability of the durability." This involves a deep understanding of a business's long-term prospects and its ability to withstand competition.
The concept of a "circle of competence" is central. The speaker emphasizes that "there is no penalty in investing if you don't swing at a ball that's in the strike zone," as long as one eventually "swing[s] at something at some point" and "find[s] the pitch pitches you like." This means sticking to investments one truly understands. Charlie Munger confirms their shared understanding of where this circle ends and where they might have an "edge in our reasoning or our experience" to evaluate situations differently.
Notable Investment Misses and Insights
The speakers candidly discuss significant investment opportunities they missed, providing valuable insights into their decision-making process and the challenges of predicting market-leading innovations.
- Amazon: The speaker "watched Amazon from the start" and considers "what Jeff Bezos has done is something close to a miracle." However, his personal rule was "if I think something will be a miracle, I tend not to bet on it," implying a difficulty in valuing or predicting such extraordinary growth. He later admits, "I made the wrong decision on on Google and Amazon," acknowledging he "underestimated" Jeff Bezos's ability to simultaneously build Amazon Web Services and revolutionize retail with speed and effectiveness, without "enormous amounts of capital."
- Google: Bill Gates had suggested Google early on. The speaker observed Google "skipping past all of this" and wondered if anyone could surpass them. He noted that Geico was "paying a lot of money for something that cost them nothing incrementally" (referring to advertising). Despite meeting the founders (Eric, Laura, and Sergey) when they were going public, the "mystery was how much competition would come along and how effective they would be." He couldn't conclude that "at the present prices that the prospects were far better than the prices indicated," leading to a missed opportunity.
- Apple: In contrast to the misses, the investment in Apple was not driven by it being a "tech stock." Instead, it was based on conclusions about "the value of an ecosystem and how permanent that ecosystem could be and what the threats were to it." This assessment didn't require understanding the technical components of an iPhone but rather "the nature of consumer behavior" and identifying things with "a lot more permanence than others."
- Airline Business: This industry is cited as an example of how competitive factors can be "extraordinary," making it a "tough decision" to invest. It "used to be suicide" due to intense competition, even with fewer players. The profitability depends on factors like the number of operators and capacity utilization.
The Role of Experience and Younger Talent
Both speakers acknowledge the limitations that can come with age, particularly in rapidly evolving technological fields. Charlie Munger humorously notes, "we were not ideally located to be high-tech wizards" and describes Google headquarters as looking like "a kindergarten," albeit "a very rich kindergarten."
A significant point is the positive impact of integrating younger talent. Charlie Munger attributes the amelioration of "some of the age related stupidity at headquarters" to the contributions of Ted Weschler and Todd Combs. He states that they are "looking at the world with the aid of some younger eyes now" and have made "significant" contributions beyond their own investments. He concludes by telling shareholders they are "very lucky to have them... because there's a lot of ignorance in the older generation that needs removal."
Synthesis and Conclusion
The transcript reveals a pragmatic and experience-driven investment philosophy that prioritizes deep understanding of business fundamentals and competitive advantages over speculative trends or complex quantitative models. While acknowledging the impressive feats of machine intelligence, the speakers remain skeptical of its direct utility in capital allocation, emphasizing the irreplaceable role of human judgment. Their candid discussion of missed opportunities in tech giants like Amazon and Google highlights the inherent difficulty in predicting disruptive innovation and the importance of valuing an ecosystem's permanence (as seen with Apple). Crucially, they underscore the continuous need for self-awareness regarding one's "circle of competence" and the strategic value of incorporating diverse, younger perspectives to counteract potential "age-related stupidity" and maintain an edge in an ever-changing investment landscape.
