Adaptive Asset Allocation
Adaptive Asset Allocation (Butler/Philbrick/Gordillo): rank the canonical 10-asset universe by 6-month total return each month, hold the top 5 weighted inversely by volatility over the same lookback, falling back to T-bills when no candidate has a positive trailing return. The published rule uses a 20-day volatility window for the weighting; v1 of the ranked primitive uses the primary lookback for both ranking and inverse-vol sizing, so the sizing volatility window here is 6-month. Documented as a v1 limitation.
