Episode notes
Pandemics Are Multiplicative Systemic Risks
- Pandemics are the dominant low tail-exponent risk because biological threats multiply with modern travel and connectivity.
- Nassim Nicholas Taleb argues pandemics pose far greater systemic danger than political violence like ISIS.
Assess Insurance Within The Whole Portfolio
- Evaluate an insurance strategy as part of your full portfolio, not in isolation.
- Use tail hedges to increase equity exposure because added stock exposure can offset insurance costs.
Stock-Bond Diversification Myth
- Historical stock–bond diversification relied on past high bond yields and stable correlations that no longer hold.
- Taleb warns that modern low-yield bonds and unstable correlations invalidate that old justification.
