Charlie Munger, the vice chairman of Berkshire Hathaway Inc., has acknowledged that both he and Warren Buffett have made mistakes during their decades-long investment journey. However, Munger emphasized that these errors were not significant due to their commitment to simplicity in their investment philosophy. In a recent discussion, he reiterated that the key to Berkshire’s success lies not in complex strategies, but in the straightforward approach to business selection.
In a 2019 interview with Yahoo Finance, Munger stated, “I can’t think of a single example in my whole life where ‘keeping it simple’ worked against us.” He highlighted that while mistakes have occurred, they were not a result of their simplified strategy. Instead, he attributed Berkshire’s competitive edge to avoiding “pompous bureaucratic systems” and empowering capable managers to make decisions swiftly.
Focus on Understandable Businesses
Munger explained that this philosophy translates into a preference for investing in businesses that are easy to comprehend and resilient against failures. He and Buffett have cultivated what they refer to as a “circle of competence,” choosing to eschew investments that seem overly complex or difficult to understand. Munger described this practice as placing such investments in a mental “too hard” pile, indicating a disciplined approach to investment choices.
During the same year, while addressing attendees at the Daily Journal annual meeting, Munger shared a humorous take on his approach to investment errors. He remarked about the benefits of diagnosing failure early on, quipping, “Who is not helped by an early start in a promising activity? And what activity could be more promising than diagnosing stupidity?” This perspective reflects his long-standing belief in reducing the risk of significant mistakes rather than pursuing high-risk, high-reward ventures.
The Importance of Practical Intelligence
Munger has frequently cautioned against what he terms “deworsification,” which he defines as spreading investments into unfamiliar businesses. He emphasizes that recognizing the limits of one’s abilities is crucial for practical intelligence in investing. By staying within their area of expertise, Munger and Buffett have consistently focused on a few key areas, allowing time and the power of compounding to drive growth.
Munger’s views are echoed by other respected figures in the investment community. For instance, Jack Bogle, the founder of Vanguard, built a movement centered on low-cost index funds and the principle of maintaining discipline in straightforward investment strategies. Bogle’s philosophy suggests that simple, well-understood portfolios tend to outperform more complicated and fee-heavy approaches over time.
Munger’s insights present a compelling case for simplicity in investment strategy. His emphasis on understanding a limited number of businesses deeply, while avoiding the temptation to diversify into areas of uncertainty, highlights a pragmatic approach that has served Berkshire Hathaway well. As he continues to share his thoughts on investment philosophy, Munger’s advice remains relevant for both seasoned investors and those new to the field.
