Episode notes
Mean Reversion vs. Trending
- Some financial indicators mean-revert over time, returning to historical averages.
- Others trend indefinitely, like stock prices, while some are constrained by factors like GDP.
Valuations and Mean Reversion
- Valuations, like price-to-earnings ratios, tend to mean-revert, but determining the mean can be challenging.
- The mean can vary based on the timeframe considered (e.g., 5-year, 10-year, 60-year).
Drip-Feeding vs. Lump-Sum
- Consider drip-feeding investments rather than lump-sum investing when valuations are stretched.
- This approach mitigates the risk of overpaying before a potential market correction.
