Episode notes
Early Career & Microcap Bubble
- In 1968, Jeremy Grantham made exceptional returns in microcaps, particularly with American Raceways.
- The stock tripled quickly due to the novelty of Formula One racing, but Grantham eventually lost most of his gains.
Market Inefficiency
- Markets are historically bad at predicting the future, with peak multiples often preceding the worst economic periods.
- Examples include 1929, the Japanese market in 1989, and the 2008 financial crisis.
AI and Market Rally
- The 2023 market rally was primarily fueled by enthusiasm for AI and the "Magnificent Seven" tech stocks.
- AI is a serious development, but its impact on corporate profits and market attractiveness remains uncertain.
