Episode notes
Match Trading Bias To Your Overall Portfolio
- Maintain directionality aligned with your broader portfolio: don't arbitrarily make equities long-only if your portfolio already holds long equities.
- If your account is your only equity exposure, a long bias may make sense; otherwise allow shorting to hedge overall exposure.
Use Simple Entry With Volatility Sized Stops
- Avoid overfitting by mixing many bespoke entry and stop rules; use simple entries and volatility-sized trailing stops.
- Carver recommends one entry (e.g., recent return) and a volatility-calibrated trailing stop sized to holding period.
Trends Work Best At Multiweek To Year Horizons
- Trend effectiveness clusters at multi-week to ~1-year horizons; much shorter horizons show noise or mean reversion.
- Carver notes equity fast-trend effectiveness declined ~25 years ago; choose multiple trend lengths rather than over-optimizing one.
