Early Investing Experience
- Markku Kurtti bought his first stocks in 1999, losing 90% during the tech bubble crash.
- This experience sparked his interest in finance and led him to study the Kelly criterion.
Compounding Process Capacity
- The compounding process capacity, derived from information theory, is the maximum achievable geometric growth rate.
- It's achieved when volatility equals the Sharpe ratio, similar to maximizing signal-to-noise in communications.
Diversification Premium
- Diversification is negatively priced with geometric returns, meaning it incurs a cost due to the variance drag.
- This cost is represented by the diversification premium, which is the difference in growth rates between a single stock and a diversified portfolio.
