Episode notes
Tech Dominates The S&P 500
- Eight of the top 10 US stocks are tech and they make up ~40% of the S&P 500 by market cap.
- Those firms contributed disproportionate shares of recent index gains, revenue, earnings and capex growth.
Concentration Often Precedes Corrections
- Market concentration has historically preceded big declines, as in 2000 and 1973 spikes in concentration.
- High concentration often signals hype and FOMO, which can reverse violently.
Network Effects Create Long Runs
- Some dominant tech firms can sustain leadership for decades via network effects, with Microsoft as an example.
- Durable moats mean big tech may persist rather than collapse quickly like 2000-era dotcoms.
