Executive Summary
John Maynard Keynes, known primarily as an economist, was also a highly successful investor, generating 16% annual returns from 1922-1946, outperforming the UK index by nearly 6% per year.
Keynes's investment approach evolved dramatically from a macro-focused speculator who went broke twice to a long-term, concentrated value investor focused on a few high-quality businesses.
Key lessons from Keynes's career include the superiority of temperament over intelligence, the importance of distinguishing between speculation and investing, and the power of adaptability in navigating market turmoil.
A concentrated portfolio, while a key to outperformance, requires patient capital and the psychological fortitude to endure high tracking error and periods of significant underperformance.
