Munger’s impact on the investment sphere is immense, and I’d like to briefly focus on the two pivotal contributions he’s known for.
#1 Extreme Patience, Extreme Decisiveness
Firstly, he advocated a binary approach to investing, which he described as ‘extreme patience combined with extreme decisiveness.’ This patience entails waiting for the right investment opportunity.
While easier said than done, most investors tend to be more active, reacting impulsively. How many can resist the urge to invest and stay in cash while others reap substantial returns? Most would succumb to chasing performance.
Unlike them, Charlie doesn’t invest on mere possibilities or take small positions in uncertain ventures. He either invests or he doesn’t. And when he does, he commits aggressively with substantial sums.
This philosophy is evident in Buffett’s approach as well, where he uses Ted Williams’ analogy of waiting for a ‘fat pitch’ in baseball – not swinging until a perfect opportunity for a home run presents itself.
Buffett initially practiced Benjamin Graham’s value approach and it was Munger who persuaded him to shift his investment strategy. This new philosophy led Buffett to invest in companies like Coca-Cola, Gillette, and GEICO, generating billions over his career.
Even today, Apple constitutes the single most significant investment in Berkshire Hathaway’s portfolio, accounting for nearly half of it. Such concentration demands immense confidence, patience, courage, and skill.
Concentrated portfolios can significantly amplify earnings but also pose a high risk of losses if misjudged. How do they minimize mistakes? Munger said Buffett and him categorize investments into three baskets: ‘yes’, ‘no’, and ‘too tough to understand,’ allocating each potential investment accordingly.
Buffett refers to this as the ‘circle of competence.’ Sticking to the ‘yes’ basket is crucial, and it’s acceptable to let others profit from markets outside their understanding. Diverging from their areas of expertise typically doesn’t yield success. It’s about choosing battles where one holds an advantage.
#2 Latticework of Mental Models
The second notable contribution is the application of multidisciplinary thinking to investing.
This approach acknowledges that not all investment queries can be resolved through financial knowledge alone. For instance, understanding Darwin’s theory of survival of the fittest in biology can provide deeper insights into competitive advantages. Knowledge in psychology is essential to recognize biases in oneself and in industry players. Applying engineering principles like safety factors to investing can create a valuation buffer or margin of safety. Munger believed that embracing a multidisciplinary approach enhances decision-making.
This may sound arduous, but Munger argued that grasping the major concepts from each discipline and forming mental models is key. By interweaving these into a latticework of mental models, one can more effectively apply them to various problems and situations.
Disciplines are human constructs, but real-world problems transcend these boundaries. Thus, a multidisciplinary approach is essential for clearer understanding and better solutions.
Munger lived to the remarkable age of 99, maintaining his health and mental acuity until the end. His was a life well-lived, and one could hardly ask for more. Though he may have passed, his ideas will continue to influence generations.
