Episode notes
Valuation Drives Long Term Equity Returns
- Long-term equity returns are driven by starting valuation and are highly cyclical.
- US equities returned ~8.5% real from 1900–2024 but that average hides long multi-decade swings like negative real returns after 1999.
US Market Performance Is Anomalous And Priced For Perfection
- Recent US equity performance has been anomalous with elevated valuations and compressed earnings yields.
- Over the last decade US equities delivered ~15% annualised and earnings yields fell from ~7% to under 5%, implying high future growth is already priced in.
Extreme Concentration Raises Crowding Risk
- Equity returns are concentrated in very few stocks, increasing crowding risk.
- Since 2020 roughly 10 stocks accounted for over half of S&P 500 returns and sector concentration sits near a 92-year high.
