Episode notes
Rethinking Diversification's Track Record
- Diversification is traditionally seen as the biggest free lunch in investing but has not worked well for the last 30-40 years.
- This challenges the classical CAPM-based investment principles and prompts a need for reevaluation and fresh research.
US Tech and Dollar Flows Drive Outperformance
- US tech supremacy, driven by profitability and low interest rates, heavily contributed to US outperformance vs international markets.
- Large capital inflows to US equities were driven by dollar strength and growth-interest rate differentials.
Domestic Flows Key To Market Stability
- Domestic investor flows are crucial to sustained equity market returns, as seen in India where domestic investors now drive performance.
- Foreign investor dependence can cause volatility during global risk-off moments, as happened in Indian markets previously.
